Recuperated glory hole

This is a recuperated glory hole project I'm doing with Marcel Braun. He hasn't really been active here in awhile but some of you may remember his postings a few years back about oxygen boosting his gloryhole so he could work borosilicate offhand. It's worked out quite well for him but he was in need of a smaller one. I believe his current setup uses 5 gallons of propane an hour and half a large dewer of liquid oxygen a session. I felt like there was some low hanging fruit in building a recuperated burner for the next one.

The dimensions are 12" by 21" inside. The burner is a two burner system with the flue in between the burners. The glory hole is made of Greencast 94 and Mizzou. I think the Mizzou is going to melt, but we will see. It is too hot for platinum thermocouples so we are backing one out into the wall and using the reading in a relative manner.

We're taking it out to East Coast Melt next week and will be doing murrine pulls and other stunts out of it. I'll report back my findings.
