When I first saw the Powder Wafers™ glue film from NO DAYS I liked the idea of being able to create any shape in glass that you could cut out of the glue film. You can use scissors and even paper punches. What kept me from trying it was the recommended firing schedule and having to keep the kiln vented for all those hours.
A) 150°F dph to 300°F – hold :45 B) 250°F dph to 600°F – hold :45 C) 250°F dph to 1000°F – hold :45 D)Continue to fire as normal
Yes you can program a kiln and not worry about it. But somehow I shy away from long firing schedules even more so now, since I heard about those relay problems people have encountered. Knock on wood, so far I have not had a relay break on me in 17 years.
Here is the mold I used for my trial. It is a small piece of Kaiser-Lee Board with an indent. I place it in the big kiln with everything else and took the risk of not even venting my kiln. In the future I will use my firing schedule (see below) and fire the pieces in a different kiln which I can vent easily until it reaches a 1000°F. This is the firing schedule I use for small pieces like this one.
A) ramp up 900°F to 1000°F hold :10
B) ramp up FULL to 1410°F hold 10
C) ramp down Full to 900°F hold 15
D) ramp down 100°F to 700°F hold 0 – let cool to room temperature!
Sorry I did not take any pictures before the firing, but here are the steps. First I placed a piece of Papyrus shelf Paper™ in the size of the glass on the mold. Then I placed the 2 Powder Wafers™ butterflies on the paper with a piece of clear glass on top. In the picture you see the the small dish after firing. Yes, it is a single layer of glass with the butterflies fused to the underside.
This is the mold and the Papyrus Paper™ after the firing. Everything is as usual. No glue residue or anything else and I’m really pleased with the crisp look of my butterflies.
In this 3rd picture you can see the mold and the Papyros Paper™ after the firing. Everything is as usual. No glue residue or anything else and I’m really pleased with the crisp look of my butterflies.
