[TheForge] one time use crucible

Sat Jun 7 19:11:56 EDT 2008

I am back to the basics here -- as per my original post.  Line a metal 
container with clay (refractory by another name)  Prefire the refractory to 
be sure it contains no WATER.  Use.  Using special or high cost refractory 
is not necessary for a 1 or few time use.  Crucibles have been made this way 
for 100s of years.  By using a metal (steel) container and a clay 
(refractory) liner the refractory does not have to have the special strength 
requirements as if it was used alone as a crucible.
