Matte glaze at low temperature too milky

Yes, Not meant to be complicated or elaborate I think it’s a reminder that cone ten is a thing because of our geology, we often do special things to make cone ten glazes melt at cone six or less.

Not really getting the parallel here. Yes cone 6 requires zinc or boron (for a well balanced melted glaze) but how you are linking this to Earth's geology melting at cone 10 I'm unclear as to your logic.

edit: I split @Bill Kielb's reply to an new thread here, post is "Why Cone 6?"
