Anyone have a good online source for these? AFAIK, there are no
pottery suppliers in my neck of the woods.

What neck of the woods is that? :)

Got mine at a brick yard in dumb ol Tucson. :)

They had several to choose from, different top temperatures and
different insulation levels. Mine are the most insulating and are
just like (no kidding) the material inside the ceramic kilns. (was
given a rusted out mess of a cermic kiln back in the late 80's)

I was at the scrapyard one day and a couple guys were removing fire
bricks from one of those rotary-glass-melters they use to make
telescope mirrors at the UofA. Another college threw his whole
works away, they found out where and high-tailed it over there and
began stripping it of the more valuable parts. :) The fancy bricks.

The bricks they were removing looked kinda like fused clear glass
beads and the guys were telling me how similar they were to the
space shuttle tiles etc. They gave me the distinct impression my
bricks were "ho hum" bricks. ;)

They looked like "mutt and jeff". :) I recognized the short fat one
right away from TV (Science channel) and later saw the tall skinny
one on TV.

Anyway, insulated firebricks would be quick and easy to fool with
but IMO, from what I've learned here, that isn't the best way to
get something worth while for forging.

"batting with a coating, inside a metal container" -a.c.b

Cheaper and better both, right guys?

West-central Wisconsin. I checked with the local brick yard, and they
had firebrick in two sizes- 1.5" thick, and 2.5" thick. The thicker
stuff was $1.60 a brick, so I am assuming (though I could certainly be
wrong) that it is the heavy firebrick. They're kind of the only game
in town.

That's the plan, a little way down the road- I'm just impatient!

Never thought about it. :)
I guess I should call for their specs and prices and post it. :)
