I have been continuing to experiment with drop through mould and painted float glass.
I have spent the last two days making little disasters in the kiln, and learning a lot from them
1. don’t watch a movie while your waiting for the kiln to hit 770. Stop and start action really loses enjoyment of the plot (not that there was one). Popping in and out, racing down to the studio, then back again, doesn’t really work, one needs to be there watching for the last 50 degrees. I programmed it to high and missed the peak, the results were obvious..
2. after you have crash cooled the kiln, check what that naughty controller is actually doing rather than what you programmed it to do. I still not sure but I reckoned it heated up again, just because it could.
3. The kiln has hot spots, I have mainly fused plates on a flat surface at these temperatures, so the fact that kiln is hotter at the front, remained a secret until now. Here is one red vase, looking rather daliesque. It fell through the mold at 760 degrees, while the one at the back had only moved a few inches
