Salt glazing was a technique used by stoneware potters to create a glassy surface. When the pottery kiln reached over 2000 degrees Fahrenheit, salt was introduced into the kiln, creating a vapor. This vapor adhered to the silica in the clay, forming a glassy appearance on the pottery. Because of the the high temperature at which the pottery was fired, the clay often became non-porous, or vitrified. This, combined with the salt glazing, meant that potters did not have to apply a glaze to the interior of the vessel. It could hold liquids and not seep, unlike earthenware storage vessels.
MAKER: Henry Remmey (1770-1865) descended from a famous New York line of potters. He moved to Baltimore in 1812 and began work at the Baltimore Stoneware Manufactory, owned and operated by the Myers family of Baltimore; they were also china merchants. The wares made in Baltimore by Remmey between 1812 and 1821 closely resemble those made in New York, with several similar features, including high-neck collars, ovoid shapes, loop handles, and cobalt blue decorations.
