Glass Separator, powdered, for glass slumping and fusing.
Coat the kiln shelf with glass separator AKA shelf primer, AKA kiln wash... to prevent your glass from sticking to the shelf. This is a 5-pound bag.
A Few Notes About Glass Separator:
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
