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 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: David Parr worked with various partners in Baltimore between 1812 and his death in 1832. Scholars at Crocker Farm Auction House note that Parr began his work in 1812 with his brother Elisha. Starting around 1815, David Parr worked with James Burland, forming the partnership Parr and Burland, which dissolved around 1823. David Parr operated on his own at Eden and Dulancy Streets following that, and later at a factory on Market Street.
