Cast in a mid-fire stoneware: Glaze is a stone-like Green - Turquoise - with sometimes gold accents - it highly varies, each will be unique depending on its position in the kiln. Inside is a crackle clear. Photos indicate the variation in glaze outcome. We may plan to do a second limited edition color after this. Mug stands about 4 ¼” tall and holds 14 oz."
