Odd….I have fused blue with clear and iridized black with clear baroque without problems I made 1” strips and counter stacked them like a weave and tack fused sucessfully at 1350. I am about to re fuse them with spectrum waterglass behind and see what happens. I want them to be less fragile…. wish me luck! I have also fused the peppermint baroque to a nearly full fuse.
I haven’t gone above 1450 though.
are you sure your glass was totally clean before firing??
Can’t hurt to try again…it will either be a lose, lose or a lose, win situation.
