Amethyst is an opaque, dark purple glaze that has a consistent, reliable result that is great for classrooms. Due to the purple pigment Amethyst might lose some of the rich purple color when fired at a higher temperature.
Several artists have experimented with this glaze in wood, soda, and salt at temperatures up to cone 12, which yielded great results!
Make sure you always test when exploring alternative firings for any of AMACO's glazes.
Tableware producers must test all finished ware to establish dinnerware status, due to possible variations in firing temperature and contamination.
(HF) High Fire
The High Fire Cone 5 glaze series combines your favorites from the legacy Sahara and Celebration glaze lines. High Fire glazes produce interesting effects in both oxidation and reduction and should be brush-applied to bisque ware fired to Cone 04 for the best results.
