I sprayed borax on the glass but not while it was in the kiln.

No I didn't. Never had to do that before. What temp. Etc. do I prefire at?

Not sure if this will show very well, but the stuff is even crystalized onto the thermocoupler. It will come off, but strange...

Yes, it seems to wash off fine. There is devit on the areas where the 'mold/snow' was heavier. I've used the same batch of fiber paper and thinfire as this before. Only new element is the stainless strips. So odd. If I put some of the stainless in my kiln alone to test, how high do I need fire it to...

This is what I found when I opened my kiln this morning. Looks like it snowed in there! A friend, who was a machinist, gave me a coil of some thin stainless steel (yes, I'm sure it's stainless). I used it to form into a circle (didn't have a mold that size) lined it with thinfire covered 1/8' fiber ...

I have no idea where this tempered glass came from. It could be 5 or 20 years old...guess I shouldn't depend on it being compatible.

Success! (After many, many tests :-2q(-_-)p) I had to do it in two firings, but I got the look/thickness/and clarity that I was hoping for! Now for my next question.... :lol: I got a lot of tempered glass from a friend (old shower doors) - do I need to keep each piece separated once shattered and us...

Yep, I'm finding that out - can't have it all. I have another test in now adjusting my top temp. Float/tempered glass is new to me, and I haven't had to do this much experimenting in while. I'm actually having a fun/frustrating time with it. Good thing I got the glass for free!! I will not let this ...

Won't I loose the individual 'shards' look (which is what I'm going for) if I fire that high?

Thanks. That's kind of what I figured...I'll give it a try and see if I get better results. Will the borax spray do any good if I'm not firing above 1400?

In making my shard bowls/plates with tempered glass, I can't seem to get the edges thick enough. I pile the shards up just as thick on the edges (on plate/shallow bowl mold), but for some reason the edges come out like one layer thick and VERY fragile - hardly fused. The middle is perfect. The only ...

I don't have a sandblaster, so I've been trying to do this in one firing (tack/slump). I have carefully sprayed a little borax with a fine mister on the last one I did, but really don't think I used enough. Do I risk much more devit if I fire it twice by tacking and then fusing, or am I better off t...

Thanks, I'll give that a try. Do you think it will make a difference if I overspray it, or am I firing it at too low a temp to matter? I use the borax spray Brad has on the warm tips site.

I was given a bunch of tempered glass from a friend who was remodeling her bathroom. Yeah! Never really worked with it before, so it's kind of trial and error (more error #-o ). I seem to have the firing schedule figured out, but can't for the life of me get smooth edges. I pile it up about 1/4"...
