what is the coe of stained glass?
 

wondering , I have seen a video of a man using stripes of glass, wondering if it is stainded glass, and he made frit by making a gather, lollipop, and dipping into cold water...
I make stainded glass pictures so i have the glass already, wondering if I could use with either my 104 soft glass or 33 boro
thanks

It varies from piece to piece. You can get glass for fusing which lists the COE and has consistency.

The COE of stained glass varies (even from the same manufacturer and probably from batch to batch of the same color) as it isn't made for melting or fusing, like the glass labeled with its COE is. I believe those are 90 and 96 COE.

If you have a bunch of stained glass scraps and want to use some, you could cut it into strips about 1/4" wide and make single-color spacers with it. Iridescent glass doesn't stay iridescent when you melt it, in case you were wondering.

There is more to compatibility than COE. Viscosity has a lot to do with it. You will see people talking about using frit of a different COE on a bead if you only cover a certain percentage of the surface with it. Sometimes that works and sometimes that doesn't.

You might be able to experiment a little with your 104 and see what happens. I wouldn't suggest trying it at all with the 33.

thank you, that helps
