Hello all,
I’m in the process of making a gas forge from a refrigerant bottle. My original plan was 2 layers of 1 inch ceramic fiber blanket, rigidizer, 1/2 inch of kast-o-lite 30, and a final layer of a zirconium silicate wash.
But after reading the posts from D.Rotblatt, the idea of rigidizing followed by a thin coat of zirconium/silica and having a forge with a much lower thermal mass is appealing. What’s bothering me about this is that my 8# ceramic blanket is only rated at 2300’F and I don’t know if the thin layer will insulate/protect the ceramic blanket from degradation like the hot face of kast-o-lite. I don’t want to save on propane at the expense of having to rip down the forge and rebuild.
My burner is a 1/2 inch Mikey burner.
Any thoughts, suggestions?
I'll cut access and vent holes in 'covers' once I know where my floor is.
