Published in "Cone 6 Glazes" by Paul Donnelly, in the February 2014 issue of Ceramics Monthly.
All work is fired in oxidation to cone 5 1/2-6, generally around 2210 degrees Farenheit. I always use a cone to determine when the glaze has matured. The Bates clear base can be very runny when fired in an electric kiln on a preset mode, which is typically 30 degrees Farenheit hotter.
