RE: BN Spray
I had the same issue, first used Slide Hi-Temp thinking it was the same as MR-97. I still have a mold sitting with stuck glass, the holey pendant mold from Creative Paradise I believe. Bought a replacement mold and actual MR-97 for the second try and it worked perfect. I had never thought about freezing – just put that stuck one in the freezer now to see if maybe, just maybe that will work!
