ZYP Boron Nitride Mold Release
ZYP is a protective
material used to prevent glass from sticking to slumping and bending molds at
elevated temperatures. An alternative to spraying shelf primer onto a hot mold, ZYP Boron Nitride forms a durable
layer that will last for many firings. Easy to use, simply spray this aerosol
release onto a room temperature mold (wear a dust mask and spray outside only
please). To date this is the best release agent we have found for preparing
metal or ceramic molds for slumping and bending.
This 13-ounce container will prime about 20 medium
molds. You may need to touch up the areas where the glass touches the mold after
4 or 5 firings. It works best if you never fire it above 1350F or 730C. Try it, it's unbelievable.
