I was plying around with building an anealing oven this weekend using a old
portable gas grill. I ran into two probs:
1. The burner worked fine with propane but was not so great with
natural gas (even if I mixed in air). Anybody know why? Pressure
regulation? I'm about to go with electric just so I can have more
control.
2. I put a pan filled with vermiculite over the burner. I then put a piece
of strained and thin glass on it. It broke even though the temp came
up pretty slow. Iv'e seen glass bead makers just plunge their hot beads
into a crock pot full of vermiculite but this isn't practical with neon.
So my question is what do put the neon on (in). The oven down at school
we have sort of a wire net that the tubes rest on. Any advice from you
experienced kiln makers.
