I am using efferete clear glass, and melting my frit onto the glass before applying it to my mandrel. I am using a shaper to shape the glass on the rod and then flattening it. I have created 2 beads the same way without problems. the last 3 beads have these pit or pin holes in them. I don't know if this was caused by too long in the flame, too close to the flame or because of too many time rapid cool in the shaper ?
