[TheForge] kaowool

[Ben Barrett]

Our local insulation supplier (and also the local ceramic & glass kiln
supply shop)
have a variety of high-temp fiber materials, after talking to the
owner about what
I was into, he gave me some scraps (cut-offs, ends) to play around
with.  I don't
know what these were, but some didn't like flame, so watch out :)

I've used ITC products on kaowool, but didn't fire the kaowool first,
and from what I've read, I think I will be trying that method again
soon.  The bits I've read about, though, house the kaowool against a
solid frame (such as a large tin or recycled gas cylinder).  I also
read some interesting stuff about using stove cement and perlite to
make DIY castable refractory -- I think a think layer of this (though
thick enough to hold itself solid) one on face of the kaowool, or even
sprayed or layered on all sides, might be useful.  Idea being that the
refractory would be thin enough to heat quickly and the kaowool would
still have insulating qualities (and then, a durable but moderately
lightweight design can be achieved).... any thoughts?  My poor ol' gas
forge is falling apart :)  At the very least, I need to fab a metal
frame for the optional spacer bricks, and also for doors on each
end... my soft brick is all crumbled up, but I may use this with the
stove cement, if I can get any further confirmation on the stove
cement, s'posed to be good to 3000ºF.  See

Very interested in other answers to your own question, Terry, thanks for asking!
