Will This Work?

I want to make a blank to use with a drop-ring (first attempt), and would like to fuse together two 12" transparent circles, with a smaller coloured circle (about 8" in diameter) sandwiched between the two larger pieces, in one firing. Glass will be Spectrum 96. The idea is to have a transparent rim to which I will tack fuse a design before the final slump.

I'm concerned that the three pieces may distort because of the size difference, or that air might be an issue. Has anyone any ideas or advice??

Many thanks and regards

Linda

You will have a bubble all the way around the 8" piece if you do this. You may be able to do it by placing small "chads" around the outside and firing very slow from around 1150 to 1250, may even want to add a soak in there for half an hour. Either that or just center the smaller circle on top of the two clear ones and fire it that way.

You can always do it in two firings.

I'm not sure she could do it in two firings either, unless she added a third 12" circle to the mix. If she full fuses the 8" circle onto one 12" circle, the edge of the 12" circle is likely to distort before the smaller circle is full fused for lack of volume - don't you think? Now if she fused the small one on top of two large ones, and then chose to clear cap in a subsequent firing, that would work fine, except she may not want the piece that thick. I guess that would depend on how far she'd dropping it - in a drop the extra layer would probably be a good thing.

if she fired the larger circle on top of the smaller circle, she would retain the shape of the smaller circle. Then she could then flip it and cap. She'd get some shrinkage of the first larger circle, but that could be managed.

Click on System 96 link above. In the Techniques section, Patty Gray will show you how to cut a rim for a circle which sounds exactly like what you're wanting to do. This will eliminate the extra layer rorblem.

Or, if you wanted to still do the third layer with out the thickness/weight... use thin sheets??

Just a thought.
