For starters, you need to make certain that you're using a shortwave uv lamp, not something else. There are several different bulbs that are labelled uv -- you need one that is at 254 nm. If you have that type bulb, then check the Old Archive for lots on how to use it. Here's one thread: http://www....

Evidently, all over Irag, the streets are delineated with depleted Uranium shell casings. Why, if it's depleted, is it so dangerous? It's a misnomer. When enriched uranium is separted from natural uranium in order to make fuel for a nuclear reactor, the byproduct (i.e., what can't be used in the re...

A lot of these old items are galvanized steel, which gives off toxic zinc fumes if heated in a kiln, so be careful heating unfamiliar metals.

Eyewear for me was the perfect example. Sunglasses = spots and headaches. Welders shades = too dark when the piece was at the bench. Didymium = headaches. Auralens Aur99 = no spots, no headaches, can see the piece AND read the heat. The first three were all suggested and used by various teachers I ...

Bullseye's fine frit is 0.2 to 1.2 mm. That's around 20 mesh, which is larger than any of the sifters that Schlaifer's carries (by the way, most of what they carry is made by Thompson Enamel). Bullseye powder is around 80 mesh, so you can use any of the 80 mesh sifters to sift the powder. (These wor...

Brock, I tried to find it, too, before I responded to you and couldn't. I think it was in a thread that got deleted because of other content. I wish that if you had been so insulted by what I said, you would have told me so then instead of waiting until now. We could have cleared it up back then. H...

Re: photo transfer to glass

Has anyone tried to tranfer using Polaroid transfer or laser copy transfer processes? The Polaroid transfer process is not likely to work because it works best on porous materials, and glass isn't porous. The emulsion transfer process (a related Polaroid process) will work on non-porous materials s...

Paul: Another technique you might want to consider is casting bllets in a box mold, creating a reverse felief. You would make a positive relief element in plaster and cast over it in a box.

I think a big factor is what browser you use. In spite of my son's insistance, I've resisted switching from Netscape to Explorer for this very reason.

Yes, high temps for extended periods of time can affect compatibility. I try to minimize this problem by going higher and for less time.

You should also check your annealing schedule. Annealing problems are also likely to show up after a few days.

What about putting clear frit in the holes? Good idea! I'd go one further and first make small beads, so that they're round. To make beads of different sizes, just sprinkle some coarse/large frit on the shelf and fire to fusing temp. Don't let the frit grains touch each other. To make beads all the...

Re: keeping holes in glass

Questions...1) Will the holes close up when I fuse it and if so, how can I keep that from happening? 2) This will be slumped as a deep bowl and I would like some design to show on the underside of the bowl - would I put my design facing down between the two layers of clear and red?

It's fiber blanket with a Dawson kiln sitter. Made for ceramics. (but fiber blanket is used in many more glass kilns than ceramic ones) Assuming the elements are still good, it should work for you. If they need to be replaced, you may also have to replace the fiber blanket. Be cautious if you distur...

Is this a new kiln or a used one? To the best of my knowledge, Nova is an old kiln name. The Nova kilns were marketed as "space age", with hidden elements. I believe the company was bought out by Duncan. I don't know if the walls of the Nova kiln were lined with fiber blanket (the most com...
