We don't recommend a 90% alumina pot for melting Boro. It would be far more appropriate to use AZS but the thermal shock issues are huge. I am constantly told that the scumming from the interaction between that glass and the pot is excessive. You can always tell a glassblower but you can't tell him much is the saying around here.
Where are we going and why am I in this basket?
