|Description: A small round redware bowl. The interior has lead glaze with a yellow slip zigzag decoration along the side of the bowl.
History: The bowl was purchased at an auction in Brampton, Ontario. It is from northeastern nineteenth-century North America. Most earthenware produced in Ontario was usually glazed, a glass-like coating that made the pottery less porous, easier to clean, and more attractive. Basic ingredients included silicates, borates, and a flux. The exact glaze mixture depended on the source of the components, the clay body of the pottery, and the firing temperature. Redware is pottery made from red firing clay that is fired in an oxygen-free atmosphere. In Ontario, most local clays fire to a red ware or yellow ware. See: David L.
