I don't think I'd do it any other way. But I'm assuming it's not to be shut off either

It can be tricky with an element melter. I was testing my first system to be sure all the connections were good...thermostat working, gauges and switches doing what they should. What I thought would take an hour took only minutes and before I knew it the temp was 300 degrees and my fresh EC pot had a hairline crack. Didn't last a whole lot longer.

I am exceedingly paranoid about my start up now but have used your crucible guide for my last couple warm-ups. Slow and steady and a good long hold at the quartz conversion point.

AH, well, that makes sense. It's OK to put all your eggs in one basket, BUT WATCH THAT BASKET! EC makes a perfectly reasonable pot. I designed most of the round bottom ones they have and they have a reasonable mix, but sort of sloppy. I don't know what a "CC" pot is. Best to splurge on a controller. In Electric it's really easy to manage.

In Texas they used to say "Diamonds as big as horse turds..."

Crucible Connection=CC

Your "CC" 80 lbers are 1" thick...that EC one was maybe 1/2". I find them much more resistant to thermal shock.

I also recall that I went with a straight walled version of the 80 lb EC...5/8" thick actually. I should have gone with the round bottom version

That was awhile ago. I didn't mean to denigrate EC...just pointing out a moment I wish I could take back.

I only did the round bottomed ones. The two 80 lb pots are the same mold.
