The first crystalline glaze appeared in Chinese porcelain during the late Ming Dynasty. It is called Fat-shan Chun after the locality in which it was produced. Inhibition of crystal formation in the reduction atmosphere found in fuel-burning kilns may account for the disappearance of crystals for two centuries.
Crystalline glazes reappeared in connection with the Art Nouveau style in the desire to reproduce antique Chinese porcelains. The earliest studies in zinc crystals were conducted in France during the 1850’s. By the turn of the century, comprehensive studies had been conducted in France, Denmark, Germany, Britain, and the U.S. In the early 1900’s, several U.S. potteries began to produce crystalline glazes on a limited basis.

Adelaide Alsop Robineau is credited with bringing crystalline glazes into the independent potter’s studio. She began working with crystals in 1904, documenting her extensive research until her death in 1929. Owing perhaps to the technical difficulties involved, there was little or no additional work until studio potters revived the technique in the early 1970’s.
