Iridized Glass? What is it?
Posted: Thu May 22, 2003 7:34 am
I would appreciate any information, photos, etc. on iridized glass. Where to buy, etc. How it fuses, slumps, etc.
Thanks

Bullseye, Spectrum and Uroboros all sell irid glass. Depending on who supplies the glass, the method of manufacture may very. I know Bullseye uses stanous chloride nad acid sprayed on the glass while it's about 1500 f.deborahbur wrote:I would appreciate any information, photos, etc. on iridized glass.

Avery does this all the time - and yes, the design stays. It's a nice surprise when you look at the bottom of one of her pieces - as if the top side wasn't pretty enough!Dani wrote:Like many fusers, I systematically use the irrid on the bottoms of all bowls to avoid kilnwash sticking.... Ron, have you standblasted a design onto the bottom of a bowl and then fused.... the design still stays there, I would presume? Might be a subtle little trick to try.....

I have blasted a design on "96" black irid, then fired it to polish blasted area. Mine always seem to have cracks in final irid exposed surface.
Fuse at 1450 after blasting, Slump at 1260.

I've just done a little of the back irid design on my pieces, but like Jackie mentioned, Avery uses the irid back to real advantage. The designs stay and look good.Dani wrote:Like many fusers, I systematically use the irrid on the bottoms of all bowls to avoid kilnwash sticking....
