I thought that was probably the case when I was getting soot on the tongs etc. I'll have to look out for a tinted face shield like yours, I've been using my old flip-up welding mask.

if you don't have enough air for the amount of fuel that your putting into the furnace the flame will climb out of the exhaust hunting for air, one of two things that you can do is 1. increase the amount of air, or 2 decrease the amount of fuel until the flame recedes back into the furnace, and a two foot flame on the exhaust port isn't going to help melt the metal.

as far as what your calling Swisscheeseium, I would just throw it in the pot next time you fire up and not make any more mention of it.


Video your pours, not so much for the rest of us to see what your doing, but so you can see all the stuff that you don't think about when your in the actual pour like that air hose you had to step over or how much easier it would be to make the pour if the mold was say 12" off the ground.
