The pot sits on top of a 1/2" kiln shelf; which in turn, is elevated by a tripod of soft brick.

I guess I thought that the system96 needed to hit that high to fully melt, but I guess that would defeat one of the reasons why nuggets were developed in the first place, huh. I haven't seen much pitting on my pots, so I didn't think that there was much deteroration going on; however, I guess if the glass is liquid enough, it could penetrate a hairline and make it a much bigger issue, huh?

Thank you for the info......

This board is an awesome resource.
