fire polishing with torch
I am sure that this has been discussed before, but I was wondering if any of you do fire polishing with a torch as opposed to in the kiln and if so, do you anneal in the kiln?
If you are talking beads or small cabs, I think it could be done and annealed just like any bead. Intoduce into the heat slowly... For a larger piece though I doubt it's doable without thermal shocking the glass.
In my early days of fusing, I also learned a few lamp working tricks. I decided I wanted to add some stringer and just tack it to a fused 6" square tile I was playing with. I thought that I would just tack the stringer on with my torch. At first I was shocked, then had a moment of clarity as the glass tile shattered. Geez, I thought, this is just what happened when I poured cold batter into a hot corningware dish to make German Pancakes... Kapow! Graphic illustration of thermal shock at work only in reverse.

Re: fire polishing with torch
In theory, you can heat the glass to above 1000º F in a kiln and then torch it to fire polish temp and then place it back in the kiln to anneal. You can do the same thing by raising the kiln temp to fire polish temp without risking the hair on your arms and eyebrows though.Jane Clifton wrote:I am sure that this has been discussed before, but I was wondering if any of you do fire polishing with a torch as opposed to in the kiln and if so, do you anneal in the kiln?
