around the brick. This time I won't to build the forge the way I wont it.
any ideas on what to use and where to get it would be a help. I am in
northern arizona.

Howdy!
A good source for fire-clay is pottery-supply stores.They are on line
too.Barring that you might be able to just use clay dug localy.I dont
reckon it would hold up as well as fire clay,but would save you a bit of
money.If your wanting to build an open top forge you have a lot more
options.Ive just finished today moulding blocks of castable
refractory,rated at 3000*,to line my charcoal forge,..but to build one
competly from the stuff would cost a bit .

People do not know,because people do not do.

thanks I will Look in that direction. I am building the fire box and frame
and like you i just need to line the thing with high temp material to save
the steel fire box from going away to fast.

thanks

Home depot sells fire clay. 50 lb. bag for a few dollars. Not much of an
insulator, but should hold up to the heat of a coal forge? I saw a receipe
on one of the bags for using cement in the clay to make bricks. Been
meaning to try that to see how solid they were. Insulation is easy -
standing up to abuse under temp and flux is not so easy ;-)

Maybe this is just a small point, but I think you want "castable
refractory". As previously mentioned, it isn't a real good insulator,
but will help protect the forge. I know a potter who mixes his
castable refractory about 1/2 and 1/2 with sawdust. The sawdust burns
out and leaves lots of spaces that add to the insulating properties.

I would not use locally dug clay. It could work, but needs to be fired
to be effective and you don't really have that option. I tried it once
in a little rivet forge. When you wet your coal, the stuff soaks up
water and becomes soft so you are getting it mixed in with the coal. As
others have said, go th a place the sells firebrick or pottery supplies
and tell them what you want to do.

Where are you? I have 5 bags of castable refractory that never gott
poured into walls of the maple syrup evaporator.
