Crystalline tumbler 8” shop

This a a wheel thrown tumbler lined inside with a food safe clear liner glaze. It is glazed with a copper glaze. I make all of my glazes.i It has been lightly etched . I make all of my crystalline out of porcelain and fired to 2345 degrees. This is one of a kind as crystalline pieces are never identical. You can control the color but not the crystals. This tumbler will make a great Christmas shop gift.
