This has been persistent with all the pots so far. Maybe not as severe before.

I don't think it's the pitting trapping bubbles. If it were it shouldn't be a problem with a new smooth pot. Shouldn't the bubbles in that case eventually rise to the top anyway? At least if you crank up the heat.

We did have a better glass with Glasma's pelletized batch. Bubbles weren't really a problem but there were some issues with cords. It too did eat up the crucible quite eagerly.

I'm inclined to think that the root of the problem is too much heat distributed right next to the crucible. I'm still wondering how the small wire melters manage to work.
