No reason you can’t refire it. It might settle back down, but it will likily have tell-tale marks or thinness. The list of causes are too nummerous IMHO to mess with. The simple solution is not to use kiln wash/primer, and instead use thin fire or other type of fiber paper. I bought a 100 foot role of the stuff 10 years ago and I stil have 50 foot left. You can fire multiples times on 1/8 fiber, then save the scrape for other projects. I often use the scrapes to form heavily decorative textures on the back of the glass. looks absolutely great if you use irid glass on the the fiber.
As you might read elsewhere about the ‘back side’ of projects… celebrate the textural effects by creating your own approach. Using primer on the shelf is boring… besides being troublesome at times.

Very early in my fusing experience I researched bubbles and gave up because there are quite a few things that cause or assist in making them. Some of which are: shelf not dried out from wash; uneven distribution of glass causing relative ‘weak’ spots where there is less glass; and firing schedules to name a few.
The shelf side of glass will always be textured or matt no matter how smooth you try to make the shelf. So why not just go with it. Fire on top of a thin fire matterial or other shelf type papers or fiber products. You will never get bubbles since air will escape via the shelf lining, and learn to love the various texture possibilities you can come up with by using all sorts of fiber based products and doing things with or on the fiber/paper.
As far as saving the piece that has a raised bubble. You can put it back in the kiln and raise the piece to bending temp. Use a stainless steel soup ladle or some such tool to push it down by rolling the ladle over the bubble, then follow a regular schedule to bring the temp down to room temp.
Since your a newbie I need to tell you to turn the kiln off when reaching into it and use a kevlar glove or some such. After you pushed it down, then turn the kiln back on and continue with the down ramp part of the schedule.

My electric co-op will let individuals borrow their meter. Perhaps other companies will do the same. They use the meters to for troubleshooting and loan them out so that their customers can calculate cost and/or look to reduce their energy consumption.November 21, 2008 at 12:46 am #10975

Hmmm can’t you just make the stuff from any regular powder? It is probably just an additive to the powder like borax or some such, right?
