Cone 6: Copper Jade fires to a gloss finish, producing colors that can range from brown-greens to creamy tan hues. Color breaks dark and can pool into red tones where thick. This glaze yields complex surfaces through movement and color variation.
Cone 10: Color changes to a red/brown with some black/copper mottling.

Tableware producers must test all finished ware to establish dinnerware status, due to possible variations in firing temperature and contamination.
