I'm using MR-97 Boron Nitride spray for my frit molds. The glass that was in contact with the mold has a satiny sheen rather than a glossy finish. The side not in contact with the mold is glossy. Am I just not getting all the mold release off? Or am I doing something wrong? How can I scrub it off? Thanks!

Anything touching a mold, whether protected with BN, shelf paper or kiln wash, is going to have a different finish than the "air side".

Thanks JestersBaubles! I think I was either misinformed, or I misunderstood because I believe I was told that part of the benefit to using BN rather than kiln wash, was so it would have a nice glossy finish. I guess I'm scrubbing for nothing. I didn't mind the finish so much when I did flowers, but I did a dragonfly and I wanted the wings to be very translucent and they're not. I was kinda disappointed.

Thanks Jim! I will!

If you want both sides to be glossy, you can either do a drop slump, blow glass, or torch work it. Contact with a mold dulls the finish, and adds texture. Partial contact with the mold is the worst, as you get some of each.

Thanks Bert! You've given me some good advice and things to think of!
