I fused a 96 COE dichroic 3 x 3 square onto System 96 black 5 x 5 using the System 96 firing schedule (which I swear by) - but this time, I got big and small bubbles. Haven't had this problem since I started using this schedule and the glass is too expensive to have this keep happening - twice now. I noticed that Roy Kapp has a photo of one he did with a double plate mold (Item# 7448) and wonder if he would share his fusing schedule with me. I have ordered this plate mold and would like to try again. Thanks! Sally

In reply to #5, I stopped having the sharp edge and other fusing problems when I began using the recommended System 96 fusing schedule found at http://www.system96.com/Pages/KnowledegBase1.html. I use the schedules listed for everything I do, even when I'm using non system 96 glass (which is now very rarely) and have not had any more bubbles, sharp edges or uneven firings. Also, I've found that if you don't use shelf paper and rely solely on the kiln wash, you may have sticking and residue problems. I found that soaking in white or cider vinegar will help remove this. You can't soak too long, so have patience.
