The traditional formula is one part silica and one part plaster (gypsom). If you can find it, 200 mesh silica flour works well.

In some areas it can be difficult to obtain silica, but you may be able to find and use flint instead. Flint is a silica based material.

I've colored test tubes by filling and emptying with a craft store dye (can't remember what it's called) that's used for making fake stained glass. I don't imagine it's very durable, but there are also very low fire colors such as Vitrea colors made by Pebeo which you can bake in your oven at about...

Looking for wholesale info for purchasing colored bud vases or colored test tubes, been on internet all day, searching floral, florist and test tubes can't find what I'm looking for. I saw one at a store, that was frosted blue color, as well as an orange. Anyone out there know what I should be look...

Top or bottom?

Speaking of WG@BE, I was looking for some info on it. Is there a info section or do I need to look in the archives? I can't seem to find it, I could be blind. No formal announcement yet. The exhibition will be in November. Most likely, entries will be due from mid August to mid September. We hope t...

Did you try to fuse the seashells within the glass or something else? (If that's what you did, then I suspect some incompatibility issues.)

A detailed firing schedule, as well as a description of exactly how the piece was configured, would help.

What I want to know... does Jerry know something that we don't know? Are Brad and Brock the same person, just alter egos? or would that be altered :lol: I'd better set this one straight. Brock and I are not the same person. We both wear glasses and our names start with the same two letters, but tha...

In my experience, firing leaves doesn't usually leave behind a "ghost image", just a little ash. And sometimes not even that. My book mentions that sometimes organic materials will carbonize and leave an imprint, but it's not predictable and is more likely to occur with things that are thicker and h...

My guess is that it's the shelves. Ceramic shelves hold the heat more than fiber, and you can usually fire faster on fiber shelves than on ceramic.

How fast are you increasing the temperature?

Actually, we're pretty starved in the US for good glass magazines, too. It's only recently that articles on kiln-forming have started to appear, and there really isn't any single publication I'd call excellent. In addition to Glass Craftsman, you might want to check out Glass Art, which tends to fea...

Well, it's actually been on Ebay a number of times, mostly from people who buy the book wholesale and then try to resell it at something closer to retail. I would imagine that being mentioned on Ebay is a long way from the kind of "famous-osity" that someone like Marty Kremer or Brian Blanthorn enjo...

By tack fusing and keeping the temperature below 1400, you're already keeping the glass from getting heated enough to flow to 1/4 inch thickness. If you heat it higher, then it will try its best to reach an equilibrium thickness of around 1/4 inch. (This is a law of physics, like gravity. Just as yo...

Hxtal is not an ultraviolet glue, it's epoxy. It's fairly expensive, but it does work well. You can get it here: http://www.hisglassworks.com

Absolutely not. Some enamels are compatible with float glass, some are compatible with other types of glass. You need to ask the manufacturer. In some cases, such as Thompson Enamel, they make versions for float glass, versions for Bullseye/Spectrum, and versions for Moretti/Effetre. They're each ma...

For System 96 schedules, click on the link to the System 96 website at the top of this page. For Bullseye, Uroboros, or Wasser schedules, click on the respective links, also at the top of the page. Once you get the the website, just look for the section of their sites with the firing schedules. All ...

This is an interesting topic, because there is a significant distinction between junk (or direct) mail and junk e-mail (or spam). I don't mind junk mail at all; I figure it means the person at least spend fifty cents to a dollar or more to send me something, and even if I don't want it it's easy to ...

[quote="kelly alge"]I don't want my customers to feel invaded.....but I don't think I'd like to get a postcard once in a great while from an artist I'd purchased from before. [quote] I guess I disagree. I would LOVE to get a postcard once in a while from an artist I'd purchased from before...

Sandy, The non-shiny surface of glass is typical for any fuse or slump firing, not just drop rings -- the bottom is always less shiny than the top. Also, you will definitely need more than one layer of glass. I just wrote an article on using drop rings for Glass Craftsman magazine. If you find a cop...

You might mean a Gryphon wire saw. It can work as a normal glass saw, or you can drill a hole, fit the blade in, and cut from the inside out.

I have to confess I can´t discover exactly what is "enamel". It is like paints? I read that Ferro Sunshine enamels are compatible with float, but couldn´t find any site that sells it on line. Is it similar to powder glass? I´ve beeig using porcelain paints on my pieces, but I´d love to try some...
