This glaze - on the other hand looks like a winner - I calculated it using
Gerstley borate rather than colmanite - it would not be hard to convert it
over to a borax frit - like 3134 for instance.
It's a high magnesia glaze by the way so look for that "buttery feel" and
maybe even cobalt giving purple blue.
Expansion is low enough that it will not craze on many cone 6 bodies -
silica and alumina are high enough that it will probably test out to be a
stable glaze.
If anyone wants to try converting it to 3134 I'll be glad to hold your hand.
