I assume that when you say a glaze looks durable at cone 6 that its alumina
and silica levels fall within the limits you use for durable cone 6 glazes.
If you have enough glassy stuff to make a durable glaze at cone 6, why
would you need more glassy stuff to make a durable glaze at a higher
temperature?
