[TheForge] High temperature cement?

[Bob Ehrenberger]

I used High temp refractory on one of my fire pots. It worked ok as a fire 
pot, but the slag/clinker would stick to the refractory. It was really bad 
when I did a lot of forge welding the flux really made the clinker stick to 
the liner. I had to chip it out every day when I cleaned my forge getting 
ready for the next fire.  The stuff we were using was designed as a chimney 
liner for blast furnaces.
