Crystalline tumbler best

This is a 8” crystalline tumbler. It is best glazed with a food safe liner glaze on the inside and a red copper crystalline glaze on the outside. It is also etched. The background is emerald green with copper crystals. This is one of a kind piece. It is made of porcelain and fired to 2345 In an electric kiln. It is wheel thrown. I make all of my crystalline glazes. This would make a great gift maybe a Christmas gift.
