Hi Jay,
This is the first I've heard about your clamshell forges. You need to write
more on the group.

Luke,

I also carry regulators and everything else needed to build gas forges. 
I also have a number of forge kits including several clamshell forge kits.

As others mentioned check the temperature ratings of the ceramic fiber 
and other refractory. You can use lower temp material behind higher temp 
refractory, but low temp stuff will not hold by itself up to the high 
heat of a forge. I prefer three inches of ceramic fiber for better fuel 
economy, although a lot of folks only use two inches.
