This mug is wheel thrown with white stoneware. White glaze and a third firing with decals images from the 1975 movie Jaws.
The decals are printed with an ink that has a high level of iron, so when fired to 1800 degrees only the iron remains. It leaves an iron colored image behind.
This mug is both dishwasher and microwave safe. Holds about 18 ounces of liquid.
