China Blue is an intense, opaque cobalt-blue glaze that has a consistent, reliable result that is great for classrooms.
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.
