A bisque doll or porcelain doll is a doll made partially or wholly out of bisque porcelain. Bisque dolls are characterized by their realistic, skin-like matte finish. They had their peak of popularity between 1860 and 1900 with French and German dolls. Bisque dolls are collectible, and antique dolls can be worth thousands of US dollars. Antique German and French bisque dolls from the 19th century were often made as children's playthings, but contemporary bisque dolls are predominantly made directly for the collectors market.[1][2] Colloquially the terms porcelain doll, bisque doll and china doll are sometimes used interchangeably. But collectors, when referring to antique dolls, make a distinction between china dolls, made of glazed porcelain, and bisque dolls, made of unglazed porcelain. When referring to contemporary dolls the terms porcelain and bisque are sometimes used interchangeably.
