Boron Nitride Spray - High-Temperature Boron Nitride Aerosol Lubricant and Dry Film Coating - Heat Resistant Mold Release Spray for Epoxy Resin, Candle Making, Welding & Casting 13 oz

This spray works wonderful as a release agent for glass jewelry casting molds. Pieces come out easy and are easy to clean.

Used on stainless glass molds. 15% less than the competitor. Works well. Tends to flake when multiple layers are added so removing excess before spraying works helps. A good product at this price point, especially if a hobbyist.

I don't need as many coats for my stainless steel molds and drapes. Sometimes I can use a mold twice because it stays intact. Clean up is easy.

For use in the kiln for making glass products

It seems like it will work as advertised but the spraying from the can is inconsistent. It sprays then sputters the sprays again making it difficult to coat anything with it. Maybe it needs more propellant?

Works as well as others for less.

I now use it to spray all my ceramic molds and shelves that I use for glass fusing

I don’t know how well this product works. My understanding is that it is not as good as tungsten disulfide which is much less expensive. The two star review is because the product is expensive and non-returnable. We ended up buying it by mistake and sought to return it And cannot. That information was not very clear to us when we bought it and are now out dozens of dollars with a product we can’t use.
