Earthenware is a porous material and must have an applied glaze in order to hold liquids. The interior of the lid is unglazed, as well as the rim of the bowl.
MAKER: Henry Adam’s first advertisement for his pottery business in Hagerstown, Maryland, was in 1805. There are no known marked or signed examples of his work. Mary Adam, daughter of potter Jonas Knode, and wife of potter Henry Adam, inherited the pottery shop of her husband upon his death in 1819. Shards similar to the Adam dish in the MESDA collection (4361) and this sugar bowl have been excavated in New Market, Virginia, at the site of the shop of Adam’s brothers, Christian and Jacob. Shards resembling Adam’s pottery have also been excavated in Hagerstown at the Hager House. MESDA has a plate (acc. #4361) also made by Henry Adam and a storage jar (acc. #4075) made by Mary Knode Adam, Henry Adam’s wife.
