What main two types of glazes are there?
Under-glaze and over-glaze
What is the first firing of a clay piece called?
No, but they make for good planters!
This is the stage of clay where the clay is soft and workable. Good for building with slabs, coils, or throwing on the wheel.
Plastic
This way of building with clay involves rolling clay into coils and building a form by attaching layers of coils on top of each other.
Coil building
What type of glaze must you put a clear coat on top of for it to be shiny?
Underglaze
What do you call the level of heat that the kiln reaches?
Cone
What do you call a stencil that you can reuse to make a clay project that is the same size and shape over and over?
Template
This is the stage of clay where it becomes stiff enough to hold a shape, but is still soft enough to carve through.
Leather Hard
This type of building with clay involves rolling out a slab of clay and attaching flat pieces together to create a form.
Slab building
If you wanted to create an intricate decorative design that does not drip down and run in the kiln, what type of glaze should you use?
Underglaze
What is the second firing of a clay piece called that creates a gloss finish on fired pieces?
Glaze fire
Anything you can scratch and create texture with
This is the stage of clay that the clay needs to be in to be put into the kiln safely. The clay is no longer cold to the touch because it does not contain much water. The clay cannot be carved.
Bone dry
To attach a piece of clay to another, what do you have to do?
SLIP and SCORE it!
Which type of glaze fires to a glossy finish?
Over glaze
What cone do you usually fire a bisque kiln to?
04
How do you create slip?

This is the stage of clay after it has been put into the kiln one time. The clay body is not as fragile as it was before firing, but is still not fully vitrified. The pores of the clay are open and ready to receive glaze.
Bisque
The type of surface decoration in which you attach pieces of clay to the main clay body.
Applique
Which type of glaze fires to a matte finish?
Underglaze
What cone do you fire a low-fire glaze kiln to?
cone 05-06
How thick can a clay piece be when you fire it?
No more than 1/2 inch
This stage of clay is the final stage. It has gone through the kiln twice. The glaze has created a glassy texture that creates a seal on the clay and the clay body is fully vitrified and rock-like.
Glaze
The type of surface decoration in which you carve out holes into the clay.
Piercing
How many coats of glaze should there be on your clay project in most cases?
3
What cone do you fire a mid-range glaze firing to?
cone 6-10
What piece of machinery do we use to create slabs?
Slab roller
