(Item # SGM-014) Boron Nitride Spray Mold Release for Glass Casting and Slumping

BORON NITRIDE SPRAY MOLD RELEASE FOR GLASS CASTING AND SLUMPING is a hexagonal form of Boron Nitride in a special aerosol formulation for stainless steel and ceramic molds. Hexagonal Boron Nitride has been used in heavy industry for decades to provide a slippery surface for molds for glass and molten metals. This form of Boron Nitride works at temperatures up to 1800°F. Shake can well and on stainless steel molds, apply a light coat, wait 15 minutes and apply a second coat. Allow to dry for 15 minutes and you're ready to go. No need to preheat the mold.

On new ceramic molds, apply 2-4 light coats about 5 to 10 minutes apart. Allow to dry 15 minutes and you're ready to go. On molds previously treated with kiln wash, remove as much kiln wash as possible before spraying.

If firing to 1350°F, you should be able to get a couple of firings before a light recoat is needed. If firing higher, it is best to give a quick spray before the next run.

As with all Boron Nitride products, once you start using Boron on a mold, you cannot go back to using kiln wash.
