glass wafer problems
I am trying to work with the powdered wafers. I made the wafers 1 1/2 inches long and when they are fired onto two layers of glass, they shrink to 1 inch and the edges are not flat but curled up. My firing schedule for the firing onto glass was 450 dph to 1200, held 20 mins, 600 dph to 1500, held 20 mins. The glass pieces are small, 1 1/2 inches by 1 1/4 inches. I've made wafers in the past and had no problems but I can't seem to get the smaller ones to fire without shrinkage. I assume that the curled edges could be fixed with a higher firing temp but I'm stumped. Help. Thanks Linda
