Fused Glass Molds Question

by Debbie Yates

I used "Slide" high temp mold release on a mold. The mold had been kiln washed but I thought I would try this product SLIDE. I used frit and fired to a full fuse. /most of the pieces fell out but 6 did not. How do I get these pieces out of the mold?

Milly's reply:

I've never tried this product, but have had the misfortune of having glass stick to fused glass molds. Try refiring the piece, but with the fusing mold upside down. Make sure you have a prepared kiln shelf or ceramic fibre paper underneath for the glass to fall on to. Re-fire slowly to slumping temp - around 1150F/620C - soak for at least 30mins. Keep watching the glass in the glass kiln - often it will separate from the mold and drop onto the kiln shelf. At this point anneal and cool as normal.
If this procedure doesn't work, you will have to break your pieces off the glass fusing molds as best as you can, and repair any damage to your mold. Good luck and hope this helps.
Has anyone successfully used the SLIDE product? I'm always looking for things to recommend.
