Is it possible to use broken fusible shards of glass in a fire pit?
Dianne

yep. glass is glass. rosanna

I have done it and it works fine, I am assuming you are talking about a gas fire pit. I usually bring the up glass to a full fuse first to round up the edges so you don't cut yourself every time you have to clean it.

Dianne, like how? A wood fired down daft barrel or a fire pit for pottery? If you mean that, then that's usually a very low temp - like 1000 F to 1200 F, which is too low temp for glass fusing.

The fire pit is propane fired and huge. 2 x 6 feet burner. After it was built my friend calculated how much glass would be needed. He thinks about 250 pounds. I suggested contacting a Shower Door replacement company for tempered glass. Then as we brainstormed, I got the idea of using my scrap glass for a decorative element.

Thanks for all your replies,
Dianne

Dianne,
You're fusing? You're not mixing different glasses from different companies, are you? If the glass is all the same COE, from the same company, you will have better results. If it's a mixture of glasses from different companies - you're probably screwed. We usually use electric, computerized kilns because you don't have to babysit you kiln. People do use gas kilns, but it sounds like too much work for me.

I think she's talking about an outdoor fire pit (aka "outdoor fireplace") that uses propane as fuel, rather than wood. Such pits are frequently populated with lava rock which is then often topped off with [expensive] decorative glass beads.

A decorative element! OH! Not actual glass work. Check!

Sure...although they're liable to look like jagged fusing glass scrap if you pour them straight into the pit. If you fire them hot first, they'll round up and look more like the stuff you buy.
