Christopher I frequently use this castable formula...got the
formula at Indiana state
University in graduate School. .The real trick is to make it as
dry as you can.....

Christopher,

For what it is worth, I talked with Dick Hay at Indiana State a
couple of months ago,
and he was showing me the (beautiful!)kilns there, including
the castable used for salt firing. He told me that he now
builds a form and wets the castable sufficiently to pour it
instead of ramming it. He concluded that since it still supports
ten tons of weight (instead of the 50 or whatever when
dry/rammed), that that was sufficient - he had no plans to require
it to support more than that. A very funny man, extremely
knowledgeable. Many kilns there, including a little wood-fired
kiln that he said could be fired in six hours; Said that no one
is using them much. Everyone wants to fire electric, so they
can set the computer and go home early ...(he said, he said, not
me...)

Somewhere along this thread I must have missed the castable formula
for salt kilns. Could you either post it again or email me
privately...PUHLEASE??? Thanks a million...a friend is quite anxious to
get a good tested formula ASAP.
