[TheForge] RE: burner flares

Fri Apr 26 01:46:00 2002

What I have is no longer made unfortunately; there are others out there
though. It's a high phosphate rammable intended to line furnaces with high
temp ammonia atmospheres and it sneers at hot borax. My present forge was
made in 95' and has seen lots of welding, there is no degredation from the
borax and only a little checking.

I'll take some pics as I put the forge together and post them with my
thoughts and opinions.

If it ain't forged
it ain't real.
Wrought iron is.
