I have a bag of zircopax, a bag of pure kaolin, silica and feldspar as well as some fire clay. My wife does pottery. Can I mix these in some combination to be an alternate to plistix or metrikote to coat kaowool or am I wasting my time?

You are right it is roxul mineral wool, which doesnt seem to breakdown like glass wool. But yea, it is probably not good on the lungs so we have a side draft going at all times. We were losing too much heat through the walls but now I lined it with kaowool.  It was our third attempt at a forge with stuff lying around  but now we know what to do.  Going to make another one for forge welding and have it lined with refractory in an old propane type canister.  WE mwlted the kaowool in this one when we introduced a bit more air so want to have something that can hit 2500F. 
I am going to build another like this but want it wider and deeper.  Its only about 5" wide inside which is too restrictive for standard forge use.  By the way this is the first time ever to forge weld that cable.  I think it is just a fluke it turned out so well!  We quenched in water from too high a heat and cracked it a bit.  Should have quenched in oil and at a dull red.

Finially got our gas forge up to welding heat and managed to make some cable damascus from 1-1/4 oilfeild drill cable.  Must have some nickel in it to resist the acid conditions during drilling.

If from cominco and in that shape i am going to bet it is a zinc annode for a ship to prevent rusting.
