Thin glass question....

Post by Alan Cross »

Is it possible to get glass to go thin in the kiln....I have some bullseye rods and was wonderinf if I cut them up small will they flaten out in the kiln?

At full fuse glass wants to maintain a thickness of 6mm. Chances are your rods will suck up trying to get to that thickness.

You can get thin glass by dropping it. Either throw a ring or between any other supports.

When glass drops it is stretched and thins out. With practice you can control the outcome.

I tried making shards in the kiln with very limited success. I set up wires across some kiln furniture about 2" apart. It sort of worked but the temperature is so finicky. At one temperature, nothing seems to be happening, just a few degrees higher and it drops dramatically. If you're watching, you can see it happening before your eyes. Glass droops every so slowly in a smooth arc between the wires; raise the temperature and it starts stretching from the rim of the wire and goes square in the bottom of the stretch. I didn't have enough patience to wait for many hours for it to finish, so I ended up with some too thin, some just right, and a lot of it too thick.

If you try it, use the darkest glass you have (if its transparents you're after).

what if you got the rods, laid them in the kiln and put another kiln shelf on top of them, making a glass rod sandwich,,,,seems like the glass would get soft and the weight of the shelf would flatten them, , and then a quick flash of the kiln would freeze them in that state,,,,would this work
