I don't think this glaze will melt properly at cone 6 for starters - the
alumina is very high. It is short of silica, the expansion is very high so

would be best on the outsides of pots where food can't come in contact with

sculptures or the outside of pots.

i have tried to move beyond the traditional confines of cone 6 in order to
creatre glaes that have more interest and unusual effects
