Hand building

Wheel Throwing

Pinch pot slab

coil

Page 3: Clay Bowls

A variety of earthy materials formed by the breakdown of granite rocks over millions of years.

PLASTIC CLAY: moldable, moist clay that can be formed into a variety of things

Page 4: Clay Bowls

Clay that is starting to dry but has not done so completely; firm clay

Feels cool and damp Very fragile, breaks

easily Can be scraped and

smoothed

Page 5: Clay Bowls

• Clay that is completely dried out (bone dry) and is ready to be fired in the kiln.

• very light brown color

Page 6: Clay Bowls

Clay that has been fired in the kiln once and is ready to be painted or glazed

White color Hard as a rock

Page 8: Clay Bowls

A special oven or furnace that can reach very high temperatures and is used to bake, or fire clay.

Page 9: Clay Bowls

• Firing is the process of baking and hardening pottery.• Clay is hardened by heating it to a high temperature, thus fusing the clay particles. • Temperature in kilns can reach 2500 degrees.

Scratching the surface of two clay pieces when joining them together

Scoring is similar to a tire tread

Page 11: Clay Bowls

a mixture of clay and water that serves as a glue and is placed on scored areas of clay.

Page 12: Clay Bowls

If slip acts as an adhesive, and scoring makes two pieces of clay like the opposite sides of a zipper, then they should stick together permanently.

Page 13: Clay Bowls

Long snake-like ropes of clay that can be joined together to form a pot, bowl, or vase

Page 14: Clay Bowls

The oldest form of pottery Native Americans –

respected the earth and only used what they needed to make their pottery. How wasteful is our culture?

Coils were pinched together to hold water and food.

Originally used the “coil and scrape” method. Then fired on a bed of coals.

There are a variety of coil shapes and types…SpiralZig-zagLinesCirclesSquarestriangles

Putting coils together to make something (bowl, vase, pot)

Joining shapes together; thick sheets of clay.

Roll out like a pancake then cut out the desired shape.

liquid glass; painted onto bisqueware pottery; when fired in the kiln it forms a translucent or colored covering.

If you choose glaze – your project needs to be fired 2 times!

Draw 3 thumbnail sketches = Quiz

Bring in a bowl from home to use as a mold.

Inside the bowl, attach your clay design (coil or slab) in an interesting & creative way.

Remember to slip and score! Smooth edges and bumps. Set out to dry Fire in the kiln Paint: Choose glaze, watercolor,

acrylic Fire in the kiln again if you

glazed.
