Utilitarian v.s. Decoration
Which one of these can you use?
Which one of these items sits on your table for decoration?
Effigy Bowl Examples
Beaver
Wooden bowl carved in the form of a beaver; eyes inset with brass tacks. Kaskaskia Tribe, pre-1797.
Sketch out Pottery Ideas
•All artists sketch out ideas before starting a new idea
•It speeds up making the bowl because clay dries very fast
four states of clay:
Plastic: clay that is soft, pliable and easy to work with.
Leather Hard: clay that has been allowed to dry slightly, making it stiffer and able to support its weight, but can still be worked on and have parts attached.
Bone Dry: clay at its most fragile state, can not be worked on at this stage
Bisque: the first firing for the clay, removes all of the water, (both actual and chemical) and carbon, The fusing of the particles has begun, yet the clay is still porous to allow for glaze absorption. It can no longer be slaked down and recycled
How to Make an Effigy Bowl
Start with a ball of plastic like clay
Pinch– The hand building process of starting with a ball of clay,
inserting your thumb and "pinching" the clay between your thumb and fingers, gradually expanding and shaping the wall into a bowl-like form.
Slip and Score
– The method for joining pieces of clay where the two surfaces are scratched up and slip is added like a "glue" to create a strong, melded bond. It is an essential step in ceramic construction, because clay will stick to itself when wet, but when will fall apart after bisque when all the water is removed. Texturing the surface gives the clay some grip, almost like Velcro.
Texture
Add texture in the Leather Hard drying stage of
clay. Use tools to make texture
and designs
Sgraffito - This comes the Italian word meaning "scratched through" and is done by incising orcutting a design through a colored slip coating to reveal the clay body.
Kiln
A furnace that use electricity,
gas or wood, but may also be fired using coal, oil, manure or even old tires.
Is used to Fire the clay till it hardens to a stone like form.
Paint Yourself Silly
Glaze – A mix of chemicals and minerals when heated to a really hot temperature melt together and form a glass like color coating on the outside of clay objects.
Objectives
Objective #2:Students will learn to pinch, join, shape, design, glaze or paint a clay effigy bowl. They will choose animal features using their own thumbnail sketch ideas.
Objective #3:Students will consider the importance of animals to our culture and why we keep them as pets, guards, etc.
