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. TIP: One coat will produce dark, greenish tones, thicker coats will add greens. Thickest applications will result in metallic red hues. Liquid may have a sandy texture from jar; do not strain, the texture will fire out.
