Dear Paul Lewing,
You say <<..If a glaze has a Si:Al ratio of 12:1 no amount of slow =
cooling is going to make it matte...>>>.=20
This seems to be a bit of a broad brush. It implies that an infinite =
amount of any or all of the Alkali Earth Element oxides can be taken =
into solution then cooled without devitrification taking place. Is this =
what you meant?
