The student of ceramic art well knows that porcelain and earthenware, although as poles asunder in their technique, do oftentimes touch one another in apparent affinity. For instance, what is more earthen than the brown crumbling body of the Dutch delft ware? It is a poor relation of porcelain. But the Dutch potter had in mind the great prototypes of the East. His dishes and his jars were an attempt to copy blue-and-white Kang-He porcelain. He covered his brown body with a white enamel and painted his tulips and his Batavian-Chinese designs to imitate the Dutch East India Company's examples he had before him. He created a new art, but he started as a copyist. Beautiful as is Delft, it is really only a simulation in earthenware of blue-and-white porcelain. Similarly in regard to English earthenware, with the noteworthy exceptions of a few types essentially true to the technique of earthenware, it is singular how peculiarly obtuse the Staffordshire potters have been to the limitations of earthenware. They have assiduously attempted to bring it into line with porcelain in its decoration and its appearance. The line of demarcation between earthenware and porcelain has become in England very indefinite, owing to the fact that true porcelain is not manufactured in this country. In consequence, the artificial composition of the body of English porcelain, where calcined bones form an addition to the Chinese formula of true porcelain, has brought it into closer relationship with earthenware than is the case in any other European porcelain. "Semi-porcelain," a term in English ceramics, is not to be found elsewhere. It is still a moot-point whether to classify Wedgwood's jasper ware as earthenware or porcelain. "Ironstone china," a hardware introduced by Mason in 1830 and copied by other potters, is earthenware, and the instances could be multiplied of confusion in nomenclature. But where, as on the Continent, only hard paste that is true porcelain in the Chinese manner is produced, save at Sèvres, the distinction between this and earthenware is most clearly defined.
