I didn't think it was possible either but you can come realy really close at least with a ball mold. Say you have a 12" diameter disc 1/2" thick and you're going to slump it in a ball mold. You've already fired the disc so one side is polished and the other kiln shelf side is rough. Normal...

Are you talking about something like this?

Test went fine. Used some standard white printer paper with printed 1/4" solid black lines. Fired to 1500 degrees x 30 minutes. Small amount of ash residue stuck to glass. It mostly scratched right off. Had to sandblast off a couple spots which could also have been kiln wash. Small price to pay...

Hmm...burn the paper. The thought did cross my mind but it seemed too easy I guess. I'll do a test and let you know.

Thanks everyone. I let you know what worked.

It's a CAD design. Can you run thinfire through a printer?

Does anyone have any tricks on how to transfer complicated glass pattern to kiln shelf? I have it all arranged on a computer generated geometric paper pattern, but now getting it arranged on the shelf without the aid of the printed pattern is the problem. Take a photo maybe? Gotta be a better way. I...

Thanks Warren - Jim

Well thank you for "the lesson"
I have read some on the subject but as this is a hobby, my time is somewhat limited - I guess I appologize for that.
Any more tips, like an example of a proper annealing schedule would be great. - Jim

Wait - what???
2 hours at 900 degrees then from 900 to 800 at 100 degrees/h then 800 - 700 at 180 degrees/h ?
Right from Bullseye technical and product information - Jim

Sorry 2 hours at 900 - Jim Schedule first piece 200/1000/10 600/1250/60 600/1700/30 took to 1700 again for second comb. Tried to comb just top layer of glass 9999/900/120 100/800/1 180/700/1 600/70/1 Schedule second piece 200/1000/10 600/1250/60 600/1650/30 combed once 9999/900/120 100/800/1 180/700...

I have attempted 2 combings now and both have cracked. Both pieces were 3 layers thick dammed with an 1/8 inch fiber paper boarder in a12 inch ss circle. First one had all larger pieces with a couple wedges of glass pointing to the center, these were the areas that I combed, used oranges and various...
