Harker Pottery Company of East Liverpool, Ohio, was incorporated in 1890 in East Liverpool, Ohio. The Harker family had been making pottery in the area since 1840. The company made many types of pottery but by the Civil War was making quantities of yellowware from native clays. It also made Rockingham-type brown-glazed pottery and whiteware. The plant was moved to Chester, West Virginia, in 1931. Harker made serving pieces of the Autumn Leaf line made famous by Hall China Company and produced dinnerware designed by Russel Wright. Dinnerwares were made and sold nationally. In 1971 the company was sold to Jeannette Glass Company and all operations ceased in 1972.
