Blenko Glass

[Vonon]

I have several partial sheets of Blenko glass plus many formed pieces that were discarded due to breakage. I've done compatibility testing with Bullseye and made a chart of "no goes". I want to break up some of the chunky stuff and fire it flat. I know it should be slow but is there a too slow? The fellow that let me climb into the dumpster said I could treat it like 90 coe. Any suggestions?

I wouldn't assume it's 90 COE, so good thing you're testing.

It may devitrify.

Too slow not really an issue.

Thank you Brad. Of the colors I tested with Bullseye, only the red developed incompatibility cracks . I actually haden't thought about devit. Maybe I'll just donate it to a local stained glass artist.

Red's almost always incompatible, no matter who made it.
