Hi. I purchased a 20" stainless steel wok with metal handles. Since the wok fit in my kiln if I placed the handles on the diagonal of the kiln, I didn't try to take them off. I sandblasted the wok, heated to 500 degrees, and sprayed on kiln wash. So far, so good. But, when I slumped a 15" ...

Although I am new to using a wet belt sander, I have a few novice's observations: I have the Covington 3 x 41 1/2" , and I have used the CRL unit. There are pros and cons to each. I particularly like the 13" back plate on the Covington unit which allows you to hold the edge of a straight p...

Dick,

I agree with Charlie. After firing, I'd try an annealing schedule more conservative than whatever you used in the first place.

I've done this myself with thinner pieces, and it worked just fine.

Steve

Ceramic or stainless steel mold?

What temperature did you slump at?

What shape is the mold? Is the glass adherent to the surface, or trapped by the shape?

Steve

Wow. What phenomenal beads! Also, a very nice web site. My son is learning beadmaking, and I've made him look at your site and the nice tutorial.

Welcome to the board.

OK Randy,

Here are my photos........

Randy, Inspired by your post, I tried this yesterday. Three pound of glass in a 5" pot. After 1 hour at 1625; 45 min and 1650; and finally 30 min at 1675, only about half of my glass had made it through the aperture. The hole in the bottom of the pot was 5/16". This created three problems:...

This was discussed a while ago in this thread:

Ron,

Nice photos and nice setup.

I almost have everything I need to try this - just waiting for the A-13 medium, and have to attach my hinges etc.

Steve

I have a set up like Cliff's. A fan set in the basement window right over the kiln (a bathroom vent fan). I almost never need to turn it on. There is very little smell or smoke unless firing lots of fiber material.

[quote="Hugo Gavarini"]Hello; But what effect did you get when blasting with SiC a colored glass surface, then firing. I believe I have read Steve got a microscopic pitting effect under a magnifier and a slight haze when seeing with the eye. Am I right?. BTW, pictures by Steve are good one...

I think also it could B the silicon pushing the iridecent in2 the glass Or binding with it in some way I cant C carbon hanging arround at the temps discussed Brian, I also tried blasting two pieces of NON iridized black and clear and fusing them face to face. Had the same hazy appearance. Steve

Hello friends, I have found this paragraph in a site which would be of use: "What causes black bubbles in glass?" Hugo, I'm sorry if my pathetic pictures give the impression that the bubbles are black. The photos are supposed to show the pits on the surface of the glass. The haze that app...

Very interesting findings Steve. Since the pits are showing up on the exposed surface it sure sounds like something is trapped in the blasting pits. You mentioned you see this even on black opal which is one color I use a lot. For me, the black is a dream to fire after blasting with aluminum oxide....

Some observations: When I first started using my blaster with silicon carbide, I noticed that the surface of certain colors of glass, particularly transparent purple, had many tiny pits on the surface. Small enough that you could only appreciate them from certain angles. From a distance it looked li...

Since irid is a thin metallic coating, commonly tin. Would it be possible a carbon-tin combination?. Is there a chemist-warmglasser here?. Hugo, I had a similar thought. One of my test pieces consisted of taking a piece of NON iridized black and NON iridized clear, blasting the surfaces and then fi...

I can send one blasted with Aluminum oxide. Would it be better on black or clear?

Steve

Steve, I'm glad you figured out the problem but now I'll be worried about Brock's Pilchuck auction piece. He posted earlier that he was in the middle of it and used silicon carbide to blast. Pam Pam, I don't have a good feeling about his piece either..... Steve ps you should be getting something fr...
