Description

Kiln wash is used to prevent glaze from sticking to kiln shelves and other kiln furniture during ceramic firings. The powder is mixed with water to a cream-like consistency and applied with a brush in two thin coats on the top surface of the shelves. Let it dry, then fire the kiln wash at 1000 °C (bisque firing) before using the shelves. 

If applied too thickly, the kiln wash may flake after firing. In such cases, remove all old kiln wash and reapply from the beginning. To maintain its protective function, the kiln wash should be refreshed regularly.
