Welcome to Clay
Clay Terms to Know:
First off what is clay??

Slip and Score: A joining technique where two edges to be attached are roughed up (scoring) and "glued" with liquid clay (slip)
Leather Hard: condition of raw clay that is still has it's moisture and it still able to mold
Bone Dry: where clay had lost all moisture and ready to be fired
Green Ware: pottery that has not been fired
Kiln: a furnace made of ceramic used to heat ceramic objects
Firing Clay: heating the dry clay to a temperature that makes changes the structure to a permanent new clay structure
Pinch Pots
Coil Pots
By beginning with a clay ball a thumb is inserted in the center and by pinching the edges out you get an even wall structure
Here long hand rolled coils are used to build upon a base and create a structure.
Clay is a product from the earth that when heated becomes hard.
Geologically, clay comes from decompressed rock. It is typically carried by water and settles together in a particular area that is mined.
Physically, clay's crystal structure is that of tiny sheets with water between them. The sheets are held together by suction but can slide past each other like a deck of wet cards.
Heat causes the clay to harden.
Slab
We already define this one. :D
Examples of Amazing Clay Art
What Now?
We will be making Nature Name plates. You will be choosing a leaf or flower from a magazine provided to sketch in your sketch book LARGE. You will then practice making your name in a graffiti style (think bubble letters) in your sketch book. You will be given two sheets of paper to transfer your sketches on to then cut out. Then you will receive a slab of clay to trace your leaf/flower and name. Slip and score your clay cut out name on to your leaf/flower. Use at least THREE different textures on your name plate.
