That was helpful. I want to build a gas forge but I want to avoid ceramic fiber. I am grateful for any hints.

- MrLeap 4y agoI've built a few coal forges. My insulating material tends to be a mixture of 2:3 plaster of paris to fine quartz sand. I bought the sand from a pool/aquarium supply store. It holds up well to the heat, but not so much the rain. I tend to remake it every 1-2 years. When it's time I crush up the old bits into a new mix so it doesn't take much more material.
- carapace 4y agoThat's awesome! Does that get hot enough to melt aluminum?
- HeyLaughingBoy 4y agoI'd be surprised if it doesn't. You can melt aluminum with a handful of charcoal briquets in a terracotta pot!
- carapace 4y agoOh really? I think the ball of aluminum foil in my junk pile is about to meet its fate. Cheers
- MrLeap 4y agoYeah certainly. If it's reasonably enclosed you can easily melt steel.
- carapace 4y agoWow! Cheers!
- moring 4y agoIf you want to avoid them for health reasons, there are types of ceramic fiber that can be dissolved by the body (water + mild acid), but they will take slightly less heat, and you'd have to protect them from, obviously, water and acids. edit: I'd still suggest to enclose them and wear a mask while working with them, but IMHO them being dissolvable makes them much less scary, at least to me.
