Thanks Tom.

I'll bet your assumption about whatever flux you use being equally corrosive is probably true. I suspect the amount of alumina in the glass is important here too.

One other thing Pete has (repeatedly) had to remind me about is that our old friend viscosity is THE major player in how fast the glass will eat the pot.

So there's one thing "for sure" about viscosity.

Lani,

While we're in history channel mode, who solved your expansion/viscosity fit issues in the early days and how?
