Today I have an interesting situation. 2 crucibles in need of tempering, and a bag of something that could potentially substitute for borax. Why is this important? Because borax can greatly shorten the lives of crucibles, though it can help them through the tempering process.


I can control my new little kiln pretty well, so i'm testing, back to back, crucibles with no treatment, and a treatment that could be considered like borax, but less likely to ruin my crucibles. Maybe. It's just an excuse to play with fire, really.
