Hi,
I emailed Patty but have not received a response. So, I am trying here. I use Patty's 8x10" dam a lot. All the first pieces I've made came out well. The last two pieces have big holes and bubbles in them. I use papyrus as she taught me in her class and store my molds in their original boxes. Please see pics and advise what may have gone wrong. Thank you!
Ginni

Not enough glass. The total glass is less than 6mm thick and that causes the holes.

There was 6mm, 3mm clear base and 3mm strips covering the top.

Still not enough glass for the temperature you fired to.
