Manganese-mottled ceramics became popular in the late 17th century and reduced in popularity by the middle 18th century. They were produced in both Staffordshire, England and Buckley, Wales. The yellowish to brownish lead glaze that is often streaked or speckled with dark brown makes it appear mottled. Sometimes a slip is used which can affect the hue of the glaze. This earthenware most often has a buff interior fabric without inclusions, but the paste does vary. While other forms such as large bowls and jars have been found, most often manganese-mottled ceramics are tankards, mugs and cups. Commonly, a manganese-mottled vessel will have no decoration or very simple decoration such as grooved lines around it or an applied or impressed mark with the initials of the reigning monarch.
