Kiln Cookies?

Why Kiln Cookies & How to Make Them

Prices include use of all studio equipment. Call ahead for availability. Clay, glazing and firing are extra.

“Kiln Cookies” are a ceramic material that is placed under a piece of glaze ware in the kiln when firing. Its purpose is to catch any drips or runs of the glaze when it goes further than the bottom of the piece. So the glaze runs onto the cookie and not the kiln shelf.

These should be flat (rolled out) slabs of clay wider than the base of the piece being fired. Leaving ample space to collect the excess glaze.

The clay used for cookies should be the same cone of the piece being fired or higher, never a lower temperature clay body.

After rolling out your clay to ¼”-3/8”, cut them into sizes that will be wider than your bases. They can be any shape, round,square, heart shaped, whatever you like. You can cut more than one size to accommodate the variety of sizes of pottery you make. To dry place the cookies between 2 flat pieces of anything that has a little weight (books, boards, etc). If you are leaving them at Potters Place or another facility, sign them as you would the bottom of your pots so they can be returned to you.

Cookies are reusable. Eventually they will have a light sheen, as if a light coat of clear glaze was applied. The sheen will not be where the pots actually sat, just around the base. You can still use them as long as the base does not sit on the surface with a sheen. Your cookies will last about 5-10 glaze firings. After the sheen covers most of the surface of the cookie, they should be discarded or retired from the cookie job.

If you are firing at Potters Place, in order to protect our shelves, we will bisque your cookies at no cost.

We are now requiring the outside firers to supply “Kiln Cookies” when delivering glaze ware.
