The Arctic Cooking Pot: Why Was It Adopted?
ABSTRACT Cross-culturally, clay cooking pots are correlated with societies situated in warm and dry climates and reliant on foods
that benefit from prolonged moist cooking. Neither of these conditions, however, characterized the aboriginal coastal Arctic, where clay
cooking containers were produced and used for more than 2,500 years. We explore the factors that encouraged pottery use in the Arctic
and conclude that the adoption of cooking pots resulted from the interplay of social and functional factors. We propose that it was
adopted (1) to meet the needs of socially constructed preferences for cooked foods and (2) to overcome specific problems associated with
other cooking methods within the local social and environmental context. We demonstrate the importance of adopting an integrated
perspective in the study of technologyone that considers how cultural values and social practices interact with environmental and
economic factors to shape technological decisions. [Keywords: adoption of ceramics, food-preparation techniques, pottery, Arctic,

A LTHOUGH FEW ARCHAEOLOGISTS think of theArctic region when they think about clay cookingpots, such vessels were important components of daily life
for the Arctic people along the western Alaskan and east-
ern Siberian coasts. Ceramic cooking vessels first appeared
about 2,500 years ago, and they remained in use until they
were replaced by metal pots in the historic period. Although
the advantages of clay containers for food processing arewell known (Arnold 1985:128144), their adoption by pre-
historic and early historic people was far from universal. In
fact, cross-cultural studies indicate that outside of seden-
tary, agriculturally based groups, most prehistoric people
found other ways to cook their foods. Despite their many
advantages, then, it is clear that the use of clay cooking pots
posed challenges to the people that used them. These chal-
lenges would have been particularly significant to the peo-
ple living in the Arctic region. Furthermore, the advantages
most commonly associated with the use of clay cooking
potsspecifically, the increased digestibility of foods pre-
pared with this technologywould have been irrelevant in
the Arctic. In this article, we explore these apparent contra-dictions and offer an alternative explanation for the adop-
tion of pottery in this region, one that relies not on dietary
food-processing requirements but on the culinary prefer-
ences of the Arctic people and the problems associated with
the use of other cooking techniques in this area.

ANTHROPOLOGICAL PERSPECTIVES ON THE ADOPTION
OF CERAMICS
Scientists have long speculated on how the discovery of
ceramic technology might have come about (i.e., Amiran
1965:242; Childe 1936:89; Moore 1995:4546; Morgan
1978:14; Vandiver 1987), but until the 1980s there existed
little research into the question of why this technology
might have been adopted. This apparent lack of interestpresumably stemmed from the rather obvious advantages
of potteryin particular, its durability compared to other
containers.
But despite their advantages, ceramic containers were
not universally used by all societies, even those in which
knowledge of the technology clearly existed. There are
many reasons why a society might choose not to produce or
use ceramic containers, but the primary drawbacks have to
do with the bulky and fragile nature of pottery and with the
challenges associated with their manufacture. Compared to
other types of containers (e.g., baskets, gourds, or bags made
of textile, leather, or animal skins), pottery is heavy, diffi-
cult to transport, and easily broken. These characteristics
can create problems for people in any type of society but
would be especially problematic for those with mobile or
semimobile lifestyles.
A second, and perhaps even more serious problem,
has to do with the challenges associated with pottery

manufacture. Ceramic production requires the presence of
water and suitable clay, enough time in one location to
produce the pot, and (in general) a climate that is warm
and dry enough to allow wet pots to dry sufficiently beforefiring (Arnold 1985:119). As with the fragility of pottery,
these requirements are likely to pose more problems for
mobile than for sedentary people. This is because mobile
populations are less likely to be near the required resources
(i.e., suitable clays) at the appropriate time of the year (i.e.,
when the weather is warm and dry), and because they may
not be able to remain in one location for the number of
days needed to acquire the clay, prepare it (through grind-
ing, levigation, aging, etc.), mold the wet vessel, allow the
pot to dry, and then fire the dried product. Of these various
problems, Dean Arnold (1985:123) suggests that cold and
wet weather are the largest obstacles to the production and
use of pottery. Because of this, pottery production tends
to be strongly associated with temperate climates (e.g., see
Figure 1). The effect of climate appears to be even strongerthan the effects of sedentism, as indicated by the historic
absence of pottery among the sedentary communities of
the Northwest Coast and its presence among the nomadic
tribes of the Great Basin (Arnold 1985:123).
In recognition of the various challenges described
above and of the fact that many preindustrial societies
never used ceramic containers, archaeological research into
the origins and adoption of pottery has witnessed two
important shifts over the last few decades. First, rather
than taking for granted the presumed advantages of pot-
tery, archaeologists have began to scrutinize more carefully
8/11/2019 The Artic Cooking Pot. Why Was It Adopted (Harry)
3/14
332 American Anthropologist Vol. 111, No. 3 September 2009
the specific benefits and drawbacks associated with its use
in particular settings (e.g., see Arnold 1985; Barnett and
Hoopes 1995; Rice 1999). Second, archaeologists have be-
gun to explore the role that social, as opposed to purely
functional, factors may have played in decisions to adopt
pottery. Most social models having to do with the adop-
tion of ceramics, however, are restricted to vessels hav-ing noncooking functions such serving or specialized ritual
purposes (Hayden 1995; Heidke 1999; Hoopes 1995; Vitelli
1995, 1999). The single notable exception to this pattern is
the model presented by Kenneth Sassaman (1992, 1995),
which considers the role that social relations may have
played in decisions on whether or not to adopt cooking
vessels in the southeastern United States.
In the following section, we summarize what is known
concerning the functional advantages associated with the
use of ceramic vessels. Because the focus of the research
presented in this article is on the adoption and use of
the Arctic cooking pot, we confine our discussion to the
advantages of cooking containers. Furthermore, becausesocial advantages are likely to be culture specific, our
discussion is restricted to an examination of functional
advantages.
WHY CERAMIC COOKING POTS? A CROSS-CULTURAL
PERSPECTIVE
The use of a ceramic cooking technology offers several pos-
sible advantages over other cooking methods. These advan-
tages, which have been summarized by Arnold (1985:128
144), include an expansion of resources in the diet, an in-
crease in the nutritive value recovered from foods, and an
increased efficiency in terms of the amount of time and la-bor needed to prepare meals. All of these advantages result
from the unique characteristics of ceramic containers: that
is, because they are both waterand fire resistant, they can be
used to cook foodsfor long periods of time, in liquids, and at
relatively high temperatures. The boiling process can steril-
ize or detoxify foods, making previously toxic foods safe for
human consumption. Additionally, simmering and boiling
can structurally breakdown the components of many foods,
making them easier to digest and utilize nutritionally. Fi-
nally, when preparing foods that require prolonged cooking
in liquids, pottery is more efficient in terms of labor require-
ments than other types of containers. As James Skibo and
Eric Blinman have stated:
Compared with other cooking containers, pottery ves-sels permit direct heating with less constant attention.Although indirect heating of water with hot rocks (as inbasketboiling)is an effectiveway to reach boiling or near-boiling temperatures, it requires continuous attention toavoid boil-over and to maintain those temperatures forlong periods of time. When ceramic containers are used,once the relationship between the heat source and thepot is established (nestled in coals, supported over thefire, etc.), constant temperatures can be maintained byoccasionally tending to the fuel. [1999:172]
Given the problems and benefits that accompany the
use of ceramic cooking technology, we might expect clay
cooking pots to be found primarily among sedentary, or
at least semisedentary, groups and among groups reliant
on food resources that benefit from the use of prolonged,
moist-cooking techniques. That such a correlation does in-
deed exist is demonstrated by both ethnographic and ar-chaeological data. For example, of the 35 fully sedentary
societies examined by Arnold (1985:112119), 32 (> 90 per-
cent) produced pottery, compared to only two of the eight
(25 percent) nomadic groups in his sample. Furthermore,
the ethnographic (Driver and Massey 1957:231) and archae-
ological records demonstrate a strong correlation with ce-
ramic cooking technology and agriculturally dependent so-
cieties, a correlation that probably has as much to do with
the foods being consumed as with the increased seden-
tism that accompanies food production. Most cultivated
plant foods around the worldor at least those (such as
wheat, rice, corn, and beans) that comprise the major di-
etary staplesare made more digestible through prolongedboiling.
Despite the near universal use of ceramic cooking tech-
nology in preindustrial agricultural societies, the produc-
tion and use of clay containers by hunting and gathering
societies is not unknown. In fact, we now know that in
most areas of the world the adoption of pottery preceded
the adoption of agriculture (Pavlu 1997; Rice 1999). Reasons
why hunter-gatherers might elect to cook in ceramic con-
tainers are similar to the reasons identified for agricultural-
ists: that is, we see ceramic cooking technology adopted by
hunter-gatherers who are dependent on foods that benefit
from prolonged boiling or simmering.
Table 1 lists a number of known hunter-gatherer so-cieties, both ethnographically and archaeologically iden-
tified, that made use of ceramic cooking technology.
(Omitted from this table are incipient farmers and other
hunter-gatherer groups that consumed significant quan-
tities of cultivated foods.) The data in this table indicate
that there exist three primary situations in which hunter-
gatherers adopted pottery: where aquatic resources com-
prised a major part of the diet, where nuts were processed
on a regular basis, and where populations needed to extract
the maximum nutrition from meat.
Worldwide, the earliest pottery is found within hunter-
gatherer societies in low latitude and coastal or riverine set-
tings (Rice 1999:32). Such locations favor ceramic manu-
facture because their climates are warm enough to allow
pottery production and because the presence of abun-
dant shellfish and marine resources would have encour-
aged sedentary or semisedentary settlement. Additionally,
for people reliant on a shellfish diet, ceramic cooking tech-
nology offers two important advantages. First, the time re-
quired to process large quantities of shellfish is substantially
lowered, because shellfish open automatically with the ap-
plication of heat. Secondly, it prevents nutrients from being
lost, as might happen from the dripping of juices over an

dug into the permafrost. How the food was prepared for
preservation and how it was defrosted played a large role
in the texture and taste of a particular meal. For example,
fermented meat acquired a much-prized sweet-and-sour fla-
vor (Starks 2007). Yet other dishes relied more heavily on
texture.Quaq(or koowhak), for example, was a favorite dish
created by partially defrosting meat. The timing of the de-frosting was critical to the flavor and texture of this dish; it
was to be thawed just enough that it was neither solidly
frozen nor too flaccid. Once the meat was completely
thawed, it its texture and taste were considered unpleasing
(Starks 2007).
Although many references exist to boiling foods in
the Arctic, ethnographic accounts indicate that boiled
foods were, in fact, merely briefly immersed in simmering
liquids (Frink and Harry 2008; Spray 2002:36). As with the
preparation of quaq, foods were said to be prepared this
way to create a favored texture. Cooked meat was said to be
best when the outside of the meat is thoroughly cooked
and almost too hot to eat, but the small center remains[frozen] like ice (Starks 2007:47). Raw-frozen meat that
had become thoroughly defrosted might also be quickly
parboiled to improve its texture, because defrosted meat
that had been neither dried nor fermented was considered
undesirable.
The point of this brief consideration of Arctic cuisine
is thatas within all culturesculinary tastes were both
culturally and biologically created (Messer 1984). A paucity
of vitamin C in the environment selected for general food-
preparationtechniques that did not involve extensive cook-
ing. However, the specific techniques selected resulted en-
tirely from cultural preferences. In the case of cooking,
there were no nutritional advantages to warming the food.Rather, the adoption of a cooking technology appears to
have resulted entirely from a biological and cultural de-
sire for a diversity of tastes and textures. Why this cooking
technology took the form of moist cooking in ceramic con-
tainers, however, can only be understood in reference to
the natural environmental conditions of the Arctic.
Cooking in the Arctic
Use of ceramic vessels in the Arctic was confined to the
western coast of Alaska and to a small strip of the northern
Canadian coastline (see Figure 1) as well as to the northeast-
ern coast of Siberia (Zhushchikhovskaya 2005). Because of
the relative paucity of archaeological and ethnographic in-
formation for Siberia, however, most of the data contained
in this article derives from the Alaskan regions.
Arctic cooking was carried out using the direct fire-
boiling method (see Figure 2; Driver and Massey 1957:228
223; Fienup-Riordan 1975:27): that is, with the pot set
directly in the fire. In the interior of the Arctic, in con-
trast, where ceramic vessels were not made, the indirect (or
stone-boiling) technique prevailed (see Figure 2). Regional
differences in the type of cooking container used reflect
differences in raw-material availability. Along the northern
Arctic coastline, where soapstone was abundant, stone ves-
sels were the preferred cooking medium (Driver and Massey
1957:229230). Only in those areas where soapstone was
not present was pottery used for direct boiling.
The spatial distribution of direct fire-boiling methods
corresponds to the distribution of the Arctic tundra. Inthe interior Arctic, where boreal forests prevailed, stone-
boiling methods were used (cf. Figures 2 and 3). As with
pottery manufacture, cooking on the tundra would have
posed challenges. Inclement weather would have precluded
cooking outdoors for most of the year, and the presence of
permafrost would have made use of underground roasting
pits difficult or impossible even during summer seasons.
By necessity, therefore, most cooking would have been
conducted indoors. In general, indoor cooking is equally
suited for either stone-boiling or direct fire-boiling meth-
ods.3 However, in the case of the Arctic, two aspects of the
environment may have limited the choices women had in
preparing cooked meals: first, there likely were shortagesof fuel wood; second, it would have been difficult to cook
inside during the cold winter months.
Wood on the Arctic coast is difficult to acquire. The pri-
mary source of fuel and wooden building material is drift-
wood, which must be acquired offshore and towed to land
by boat. Two lines of evidence suggest that the availability
of such material was limited prehistorically. First, there ex-
ist historic accounts to suggest that shortages of wood were
commonplace (Fienup-Riordan 1983:56; Frink 2003:224).
Second, evidence suggests that even on those occasions
when driftwood logs might have been readily available in
the ocean, the effort required to tow them to shore would
have been substantial. Even today, when motor boats areused to tow the logs, wood is considered a valued resource.
In prehistoric and early historic times, when the logs were
towed by kayak, we infer that the resource would have been
even more difficult to obtain.
That cooking was largely an indoor activity is cor-
roborated by archaeological and ethnographic evidence
(Dumond 1977; Oswalt and VanStone 1967; Staley 1992).
In the interior of the Arctic, houses were constructed of
wooden planks; on the western Alaska coast, however, they
were made either of driftwood logs covered with sod or sim-
ply of large sod blocks. Cooking inside these sod-covered
homes would have created a number of problems. First, to
remain structurally solid, the sod superstructure could not
be allowed to melt. Second, the poor venting inside these
structures, which also served as living quarters, would have
posed substantial risk to the respiratory health of the in-
habitants (Boadi and Kuitunen 2006).
Given the difficulties associated with acquiring fuel
wood and with having cooking fires lit inside the homes,
we propose that the Arctic environment encouraged the
use of cooking methods that minimized the amount of
fuel needed and the amount of heat released. To evaluate
whether the direct fire-boiling method is more efficient in

terms of fuel usage and cooking time than the stone-boiling
technique, a series of experiments were undertaken.
A COMPARISON OF DIRECT VERSUS INDIRECT
COOKING
Two sets of experiments were undertaken to determine
whether more fuel is required by the stone-boiling tech-
nique than by the direct fire-boiling method. Containers
used during these experiments include the following: (1)
a waterproofed basket, (2) replicas of Arctic-style cooking
jars, and (3) replicas of prehistoric Southwestern U.S.-style
cooking jars (see Figure 4).
The basket, commercially purchased, was a handwo-
ven replica of an African Zulu beer basket. This basket
was selected because it was advertised to be woven suffi-
ciently tightly to be waterproof. The basket measured 20
centimeters at its maximum diameter by ten centimeters
in height, and when filled to the rim, it had a capacity of1,700 milliliters.
The ceramic replicas were made by Andreas Charest, a
graduate student at the University of NevadaLas Vegas. A
total of six vesselsweremade, three of each style.The Arctic-
style vessels were fashioned after Thule-style jars, which ap-
peared in the Arcticat about 1000 C.E. and continued in use
until well into the historic period. Unlike the rounded cook-
ing pots found in most other areas of the world, Thule cook-
ing pots are flat-bottomed with straight (vertical or slightly
flaring) walls. Additionally, they are characterized by thick
walls, low firing temperatures, organic or mineral tempers,

and coarse, soft pastes that easily disintegrate (Dumond
1984; Larsen 1950; OLeary 1999; Oswalt 1955; Redding-
Gubitosa 1992).
To make replicas of these vessels, a mixture of 70 per-
cent dry ground clay, ten percent chopped hay, ten per-
cent coarse (0.5 mm1.5 cm) sand, and ten percent fine(0.5 mm) sand was used. The clay used to make these and

the other vessels used in this study were primary clays col-
lected from the Shivwits Plateau of northwestern Arizona.
Once these materials were thoroughly mixed, the paste was
wetted and allowed to age for 48 hours. Following this ag-
ing process, the vessels were manufactured by creating a
round, flat base to which thick coils were added. The coils
were then pinched together and scraped to obliterate thecoil junctures, but to matchthe coarse texture seen in Thule
sherds, the walls were not smoothed or polished. The ves-
sels were made to relatively standardized sizes of about 15
centimeters in diameter at the base by 1213 centimeters
tall, with wall thicknesses that ranged from 1.5 to 2.0 cen-
timeters. Their capacities averaged about 1,200 milliliters.
Once the vessels had dried to the leather-hard stage, they
were coated with seal oil (a technique reported ethnograph-
ically; see De Laguna 1939:339; Fienup-Riordan 1975:14)
and fired in a Raku kiln under neutral atmospheric con-
ditions. The vessels were fired to a maximum temperature
of 800C, although the target temperature was lower and
for most of the 20-minute holding time the temperaturesranged from 690C to 750C. After the vessels had cooled,
they were again coated with seal oil to follow the proce-
dures reported ethnographically (Fienup-Riordan 2007:48;
Oswalt 1952:20).
The Southwestern-style pots were produced to mimic
the general attributes of cooking pots associated with the
Ancestral Puebloan cultures of the prehistoric northern U.S.
Southwest. In contrast to the Thule pots, Puebloan cook-
ing pots are usually rounded in shape, are finer tempered,
have harder pastes, and are thinner walled. Accordingly, the
production techniques used to produce the Puebloan-style
vessels differed from those used to make the Thule repli-
cas. Two of the jars were made using a recipe of 80 percentdry clay, seven percent ground sherd (measuring 1.0 mm

in size), and 13 percent mixture of ground igneous rock
(0.7 mm0.25 mm in size), ground olivine (0.125 mm
0.5 mm), and sand temper (0.25 mm). The third jar was
made using 80 percent dry clay and 20 percent ground
sherd (0.7 mm1.0 mm) temper.Once the dry clay and tem-
pering materials were thoroughly mixed, they were wetted
and allowed to cure for 96 hours. The vessels were thenmade using the coiling and scrape method. All vessels were
spherical in shape, measuring about 18 centimeters at their
widest point, 1415 centimeters tall, and having a 7.0- to
7.5-centimeter diameter orifice. The vessels capacities av-
eraged about 1,600 milliliters. All vessels were fired in an
electric oxidizing kiln to a maximum temperature of 750C,
with a 20-minute soak at that temperature.
Prior to initiating the first set of experiments, all of the
containers were filled with water to ensure that they were
waterproof. All three of the Puebloan-style vessels held wa-
ter without leaking. The basket and the three Thule-style
pots, however, were found to badly leak. Accordingly, addi-
tional steps were taken to waterproof these containers. Weelected to coat the interior of the basket with commercially
purchased roofing tar, a procedure that we believed approx-
imated the waterproofing techniques used by Native Amer-
icans, who were known to coat their baskets with pinyon
pitch or asphaltum (Braje et al. 2005; Buskirk 1986:186;
Frisbie 2001:35). To waterproof the Thule-style vessels, we
filled the vessels with water to which a few tablespoons of
seal oil had been added. The pots were then placed in an
oven and the contents brought to a low simmer. Although
the liquid initially leaked out, after only a few minutes the
pores became plugged and the leaking stopped. Again, this
technique was selected because we believed it likely mim-
icked what happened to actual Thule pots during the Arcticcooking process.
Experiment 1
In the first experiment, commercially purchased firewood
(in this case, pine logs) was used to determine the length
of time needed to bring water to a boil using both the
direct-boiling method and the stone-boiling technique.
Both the Thule-style jars and the Puebloan-style jars were
used in the direct-boiling method; for the stone-boiling
techniques, the Thule-style vessels and waterproofed bas-
ket were used. The direct-boiling experiments were carried
out by building a fire and, once the fire was determined tobe burning well, by placing the water-filled vessel directly
within the fire. All vessels were filled with one liter of water,
and all vessels were capped with a ceramic lid to improve
the cooking efficiency. In all cases, the lids were briefly re-
moved first at three minutes, and then every minute there-
after to determine when the water began to boil. In the
stone-boiling experiments, fires were again lit and, once
they were burning strongly, small (ranging from five to
eight cm in diameter) river-rounded basalt cobbles were
buried within them. As in the direct-boiling experiments,
the containers to be used were each filled with one liter of

water, but in this case they were set off to the side, rather
than in, the fire. After 15 minutes, the rocks were removed
from the fire and placed in the vessels (see Figure 5), and
it was recorded whether or not the water was brought to a
boil.4
The results of these experiments are presented in
Tables 2 and 3. The results of the direct-boiling experiments
indicate that it took an average of 4.7 minutes to bring wa-
ter to a boil in the Puebloan-style jars and 10.2 minutes
in the Thule-style jars. The increased heating time needed
for the latter jars is not surprising, given their thicker walls
and higher porosity as compared to the former vessels. The
data presented in Table 3 indicate that it took an average

of 14 minutes to bring the same amount of water to a boil
using the stone-boiling method. Clearly, the stone-boiling
method does require a lengthier heating time to achieve
the same result, although the relatively small difference
and overall short period of time needed for stone boiling
suggests that the differences in time may not have been
behaviorally meaningful to the Arctic people.
Experiment 2
Following completion of the first experiment, we con-
ducted a second set of experiments using smaller pieces
of wood. This second experiment was designed to more
closely mimic the fires that we thought were likely to have
been used indoors; the large pieces of firewood used in the
first set of experiments are likely larger than those used in
most indoor hearths. Accordingly, we conducted the sec-
ond set of experiments using small pieces of commercially
purchased starter firewood. The pieces of wood were of a
fairly standard size, with the typical piece measuring about
25 centimeters long by two centimeters in diameter. Thestarter wood, known as fatwood (see Figure 6), was har-
vested from the heart of old pine stumps and contains sub-
stantial quantities of pine pitch, which makes the wood
light very easily. The fatwood was considered a reasonable
proxy for wood soaked in seal oil, a material observed to
have been used as firewood by the junior author (Frink).
The second set of experiments was conducted by the
senior author (Harry) and involved only the Thule-style
pots. In the first part of the experiment, three different
Thule-style pots were filled with one liter of water, covered
with a ceramic lid, and set directly on the fire built from
the fatwood pieces. Pieces of wood were added as necessary
until the water was brought to a boil, and in all cases thefewest pieces of wood were used as possible. Once the water
reached a boil, the experiment was halted and the number
of pieces of wood used was recorded as well as the time
taken to bring the water to a boil. In all three instances, the
amount of wood used and time taken to bring the water
to a boil was remarkably consistent. On average, the direct
fire-boiling method using the starter wood required about
15 minutes and 20 pieces of wood to bring the water to a
boil (Table 4).5
In the second part of the experiment, a small fire of
starter wood was built and stones placed in or under the
FIGURE 6. Experiments conducted with the small pieces of fat-wood. Upper frame shows the size and quantity of fatwood used

fire. Wood was added as necessary to keep the fire burning,
and at a predetermined point, the stones were removed andplaced into the container of water. Three different trials
were carried out (Table 5). In the first trial, 18 pieces of
starter wood were used, an amount similar to that needed
to bring the water to boil in the direct fire-boiling tests.
After ten minutes, when the starter wood was beginning
to die down, the rocks were removed and placed into the
water-filled pot. Although the rocks heated the water, they
did not bring the water to a boil. In the second and third
trials, increasing amounts of starter wood were used in an
attempt to determine how much wood might be needed
to sufficiently heat the rocks to bring the water to a boil.
During the third trial, 88 pieces of wood were used, an
amount more than four times of that which was used inthe direct fire-boiling tests. Despite these greater amounts

of fuel wood, we were still unable to bring the water to a
boil. In fact, the highest temperature achieved was 61C,
well below the 100C needed for boiling.
Discussion
The data presented here demonstrate that, when there is
no need to conserve fuel, the stone-boiling technique can
be quite efficient. It requires no more time to bring water
or broth to a boil than does the direct fire-boiling method
(although of course, to sustain these temperatures wouldrequire more effort). When fuel is limited or when there is
a need to keep the fire small, however, the direct fire-boiling
method is significantly more efficient, both in terms of fuel
wood and in terms of time. In fact, our results indicate
that, under these circumstances, boiling water using the
stone-boiling technique is at best impractical and perhaps
even impossible. This results because insufficient coals are
generated from these small fires, making it difficult to keep
the stones smothered by the fire.
CONCLUSIONS
In this article, we argue that the adoption of the Arc-tic cooking pot can be understood only in reference to
both cultural and functional needs. That is, we propose
that the Arctic cooking pot was a functional solution to
a socially created need. Following the anthropological ap-
proach advocated by Pierre Lemonnier (1986) and Bryan
Pfaffenberger (1988, 1992), we view technologyas a cultural
choice. To understand how and why particular technologi-
cal choices are made, we support the adoption of a holistic
approach that simultaneously considers the entire cultural,
environmental, and economic context of the society under
study.
In the case of the Arctic cooking pot, we believe that
its adoption resulted from the interplay of several culturaland environmental factors. How the Arctic people elected
to prepare their food was, in part, nutritionally driven. A
paucity of vitamin C in the Arctic environment helped se-
lect for techniques that would preserve this important re-
source. Yet, there existed a wide variety of techniques ca-
pable of doing so that did not involve heat. The desire for
cooked foods was culturally created; it was a cultural-
specific culinary preference resulting from socially trans-
mitted experiences (Messer 1984).
Even so, there was still nothing in the culturally and
nutritionally favored cooking methods that required the
use of ceramics. The brief cooking times that were called
for could easily have been accommodated by stone-boiling
techniques that would not have required the use of clay
containers. Given the difficulty of making pottery in the
Arctic region, we might expect stone-boiling methods to
have been preferred. And, indeed, these methods were fa-
vored wherever wood was plentiful and houses were con-structed of materials that could withstand interior fires.
In the tundra regions, however, where wood was scarce
and houses were made of unprocessed earth or sod, direct-
boiling methods were used. Direct boiling was conducted
in soapstone wherever it was available; it was only where
soapstone was not readily obtainable that ceramic cooking
vessels were produced.
These correlations suggest that, despite the rather sub-
stantial challenges involved in making the pots, the ce-
ramic cooking vessel offered significant advantages to the
Arctic people. Furthermore, these advantages clearly were
perceived to be important enough to offset the difficulties
and inconveniences involved in their manufacture. But un-like most areas of the world where ceramic cooking vessels
were adopted, the benefits had nothing to do with the need
for sustained cooking. Rather, we argue, they relate more to
the needs to meet socially created culinary preferences, to
conserve fuel resources, and to preserve the livability of the
homes than to any improvements in the nutritional quality
of the foods being prepared.

Acknowledgments. This research was supported by a National Sci-ence Foundation Office of Polar Programs grant (#0452900, Pro-gram Officer Anna Kerttula de Echave). We would like to thankAndreas Charest for making the ceramic vessels and Mark Slaugh-ter for his help preparing the figures. Additionally, we would liketo thank Tom Boellstorff and three anonymous reviewers who pro-vided comments on an earlier draft of this manuscript.1. Vessels that begin to sinter before the clay body is completelydry (i.e., before the chemically unbound water has been driven off)will explode in the firing process.
2. Experiments suggest that these vessels could be shaped in aslittle as 20 minutes.3. Of course, the use of stone-boiling techniques requires the pres-ence of suitable cobbles. (Because stones used in this techniquecan only be reused a few times before fracturing [see Sassaman1995:228229], large quantities of stone are required when this isthe primary cooking method.) For coastal communities, stone cob-bles can usually be easily found on the beaches. For inland deltacommunities, however, a paucity of useable stone may have beenan additional factor selecting against the use of the stone-boilingtechnology.4. Previous informal experiments had suggested that the rockswould need to be in the fire for about 15 minutes to become hotenough to bring the water to a boil. Those experiments indicatedthat, when kept in the fire for ten minutes or less, one liter of watercould not be brought to a boil using only three stones, whereas the

same number of stones kept in the fire for 15 minutes was alwaysable to bring the water to a boil.5. In volume, the 20 pieces of wood translate to about 1,2001,300cubic centimeters of woodapproximately the amount of woodthat would fill a liter-sized container.
