STEP 1: ON A NEW KILN: Mix up a batch of kiln wash, aka shelf primer. You want the mix to be somewhat thick for this application, close to the consistency of heavy cream. Then, paint the floor of the kiln with a heavy coating of the mixture. We recommend going about a half-inch up the side as well. Repeat this process 3 times. This protects the fire brick from glass that lands on the floor of the kiln. Make sure NOT to get any shelf primer on the elements/coils. Check this coating every few months to assure the floor of the kiln is well protected. Reapply as needed.

STEP 2: MORE KILN WASH: Now, you are going to thin down the kiln wash to a nonfat milk consistency. Paint your shelf by applying kiln wash in complete thin coats. First in one direction, then in the opposite direction, varying north/south, then east/west, etc. You’ll need about 5-6 coats to properly protect your shelf from glass adhesion. Thin coats are always preferred over thick ones. Applying the kiln wash that is too thick will result in the kiln wash peeling back from the shelf after just one firing. It’s really annoying when that happens. If it does, just scrape off all of the kiln wash and start over with thinner coats. This step should be repeated as needed. If the kiln wash is gauged, scratched, or chipped, that’s when it’s time to scrape the shelf clean and reapply
