This very large mug came to the American colonies, in the early 18th century, via the British. It holds between 29 and 32 ounces and stands 6" tall by 5" at the base. The glaze is black and breaks brown along the lip and handle. The glaze will vary some what from firing to firing and may or may not look like the tankard pictured. Just like it would have varied in the 18th century.
It's offered in one size and one color only.
