KILN WASH

KILN WASH is a combination of refractory materials mixed with water (for application) and applied to kiln shelves or posts to protect them from glaze spatters, drips and runs.

Avoid creating or inhaling airborne dust. We strongly recommend dust masks or better protection, plus workshop goggles or other eyewear, when handling the dry powder. In spilled, clean up with damp sponges to avoid lifting dust into the air. We also recommend this personal protective equipment when cleaning or scraping kiln shelves.

DO NOT APPLY KILN WASH TO ELEMENTS, FIRE BRICKS OR OTHER PARTS OF YOUR KILN.
-Mix the dry Kiln Wash powder with water to a consistency roughly equal to skim or 1% milk.
-Apply several coats to kiln shelf with a soft brush, allowing the solution to soak in or dry between coats. Brush on successive coats in a criss-cross pattern: brush each new coat across the brushstroke direction of the previous coat. (This is optional, but some clay artists prefer to do it this way.)
-You’ve applied enough when you can no longer see the color of the kiln shelf through the dried kiln wash. The number of coats may vary depending on how much water you mixed with the dry powder.
-Scrape off any drips, runs or spatters of glaze from your kiln shelf after firing. The drips will take some of the kiln wash coating with them: that’s normal and to be expected.
-Your application of kiln wash has a limited lifespan. You’ll know it’s time to completely scrape off the kiln wash and start over with a fresh application when the kiln wash begins to crack, curl or peel off the kiln shelf.
