Great job everyone! Love my goodies! (Charles Hall...YOU HAVE ABSOLUTELY TOO MUCH TIME ON YOUR HANDS! HAHA)

Is there a website (besides BE) that has annealing schedules for large, thick castings? Especially interested in float glass.

I see everyone who signed up got their mags in and sorting should be on this weekend. Sue, you need to post some pics of the sorting/mailing etc. That's always a blast!

Will pay for prototype and process to teach us to make a sand mold for a flat 1-layer glass production piece. 18x18 with bumpy texture underside. Tried Castalot but depressions too deep to allow air escape. Sand works best, but techinique needs refining. Must be easily repeatable for production. PM ...

Me too. My tests are not going well....

OK, no responses. How do I access the search you recommended?

Some good friends are traveling from the US to New Zealand for a month and would love to visit glass studios--particularly cast and thick glass artists. If you are open to visitors, please send me your websites (via PM is fine) so I can forward. Thanks!

Thanks. I hadn't looked up Green Diamond. After I was told it was 3x the cost of olivine, I didn't pursue it. I'll get a bit from the foundry and test.

Bert, I appreciate your response. But please read the post again. there is no olivine.

I have just been told by the foundries that olivine is no longer available.The foundry is using a product called Green Diamond, which they say is just crushed glass. So. what are the glass casters using instead?

I have the book. Forgot it was in there. He is using olivine. would there be any difference in using playsand?

I am needing a basic, step-by-step tutorial on making a 12x12 open-faced sand mold using "play" sand. Need to impress a pattern to come out crisp and sand-free. I also have some olivine sand, but more "play" sand. Help, please. Thank you, in advance.

It would be helpful if this list, and updates, were pinned to the top of the thread. I really didn't know how many to make until I found this.

I did try the garbage disposal, which worked for about 3-4 times...then jammed.

Mapei makes a product for this but I do not have the info on this computer. email me for info. Otherwise I will try to post from my shop computer.

Our low-tech frit machine is a cement block and a hammer. Works extremely well, with no metal fragments. Just make sure you don't have cement in your frit by using an encasing material like foam (newspaper degrades too much).

I use equal parts of: Plaster of Paris (from Lowes) Diatomateous Earth (swimming pool filter media from Walmart) to which I add about 5% kiln wash (Hot Line or Bullseye) It may not be "the best" mix, but the only exotic stuff is the shelf wash, which you should already have. This mix can ...
