Help! I've just started using my Studio 8 Kiln and I am having problems with the ceramic molds that came with my kit. I've broken 3 of them already!! I used the Primo Primer and put on 5 generous coats with ample drying time between. I think I am heating and cooling the glass slowly enough and I've tried to remove the glass from the molds at different temperatures. When I managed to pry one out it brought a lot of the bottom of the mold and the post with it.... Any ideas? Am I heating the glass too much or for too long that it is burning onto the mold? Thanks for any help!!
