BUCKLEY EARTHWARE: C. 1720–1775, North Wales. The body of this earthenware is quite coarse because of the combination of two different types of clay in the process. The ware is made of layers of pink-firing and yellow clays. The combination of the two clays served to make the poor clays more workable. The ware is decorated with a black lead glaze. The exterior fabric color on unglazed portions is purplish-red. The body exteriors are often heavily ribbed. When broken, the fabric interior exhibits the characteristic red and yellow layers.
