[TheForge] RE: burner flares

[Larry]

4000f rammable?  Now that sounds like the stuff I've been looking for.  Let us
know how it turns out.  I have some old burners from a water heater from
sometime way past that I am working on using for a forge and a bronze foundry.
Could use some of that high temp refractory for it.  I was hoping on doing a
similar trick for these burners as they are short but have a great built in
venturi and removable jet.  As I have about a dozen, I figure I have a couple to
play with to get it right.
