|Description: A red earthenware jar. The body is covered with a pinkish grey slip glaze. It has a small mouth opening at the top of the jar. |
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 redware or yelloware.
