This is interesting...I seem to recall discussion of this kind of glass a while ago...

Not sure if I'm following you here, Lucho...those that do, as an example, geometric optical sculpture, say of a pyramid, would need to polish all five sides, and all those sides would first need to be flat to do that...are you saying that you use a wet polisher to conform to irregular surfaces? I tr...

I'm wondering if the problem might be using float in a high temp. melt. Does anybody else have any experience doing this, cause I think pretty much the advice given so far works with the 90/96 stuff... Do you use float exclusively? Sorry about those "Horns..."

Barbara, I agree on the flip and fire technique to recede bubbles, but will the shelf side heal her craters, or create more problems with trapped air in them? My thinking was that the 1500 degrees (or whatever float would be) would allow a liquid surface, but would not reduce the viscosity to the ex...

I would be curious to know if holding at 1500 on the way down closed up the bubbles. Never would have thought of that but it might work. Not sure if 1500 is the right temperature, how much is float and how much Youghigheny? Where would you full fuse that mixture - you want to be on the high end of ...

As far as the kiln-carving not being crisp, my experience with 96 Irrid, which I believe is Tin Oxide, is that it does not stretch nearly as well as the non-96 Irrid, which is Titanium Oxide, but does burn off if fired up. I think the bubbles have to do with your rapid ramp to process temp, as your ...

Footnoted with my name! Well now, ya hear that, Toni!? :P Are you :mrgreen: ? One other thing, Bea. You might want to look at the glass to determine if it's done "healing". Although it's hard to tell what's going on with that intense, strange light, especially with those green glasses (You...

Thanks, Tony & Ronny... I will defintely add the extra step at 1500 to prevent craters. Meanwhile.. Q: Can I refire to smooth the small craters? If so, would I full fuse with top cratered surface UP or, flip and fire with top DOWN at 1500? Or, what? I would full fuse with the top cratered surfa...
