iridescent glass firing

[petra kaiser]

I would love to talk to Jim Gregory – we have had lots of success firing with iridescent glass at regular temperatures using Kaiser Lee Board of course and fiber paper (both are pre-fired products and we never had a problem and perfect detail) – Are you sure he meant fiber paper or may be thin fire paper? Many people are confusing those two. The problem is, those high temperatures can cause sharp edges when you fire single layers of glass.
