The designs of Dorothy Doughty for the Worcester Royal Porcelain Company, in England, and those of Edward Marshall Boehm, at Trenton, New Jersey, established a new development in decorative porcelain. Characteristic of this kind of work are the American birds of Dorothy Doughty issued in limited editions by the Worcester Company. They are especially remarkable for technical advances in preparing the article for firing, which allow the material to be treated with much greater freedom than hitherto. Porcelain becomes very soft when it reaches the point of vitrification, but, using an elaborate series of props to support free-floating parts, the Worcester technicians succeeded in firing designs that would have been completely impossible earlier. Associated with these models are exact reproductions of natural flowers that also excel in complexity and verisimilitude anything made in the past.
In the early part of the 20th century, Bernard Moore experimented with Chinese glazes (see below China: Ch'ing dynasty). He produced some successful flambé and sang-de-boeuf glazes on a stoneware body at his small factory in Stoke-upon-Trent. He worked in association with William Burton of Pilkington pottery in Manchester, which made experimental decorative ware of all kinds.
After World War I, figure modelling worthy of the old Meissen tradition was done by Paul Scheurich, Max Esser, Paul Börner, and others. The early red stoneware was also revived. This renaissance was halted temporarily by World War II, but production was resumed by 1950. The wares exported from the German Democratic Republic into western Europe were excellent in quality.
A factory that has preserved its traditional reputation for fine porcelain is Nymphenburg, at Munich, now the Staatliche Porzellan-Manufaktur Nymphenburg. At the beginning of the 20th century it began to use a wider range of underglaze colours with the aid of colour chemists from Sèvres and, about the same time, reissued some of the old figures and services of Bustelli and Auliczek (appropriately marked). Attention was soon turned to services of fine quality in the modern idiom, and excellent figures by Resl Lechner and others were produced. Lechner succeeded in adapting the 18th-century styles to 20th-century purposes in a manner that is an object lesson to those manufacturers who insist, even today, on adding the scrolls and flourishes of the Rococo.
Such factories as Rörstrand and Gustavsberg in Sweden and Arabia Oy in Finland have achieved a growing reputation for excellent design in the modern idiom (Figure 133). The emphasis on form in present-day pottery is to a great extent due to the import of Chinese wares of the Sung dynasty (see below China: Sung dynasty) during the 1920s.
The pottery of the United States bears comparison with that of any other country, and standards are constantly improving. Technically, the United States is perhaps ahead of much of the rest of the world. The growing appreciation of good pottery design has led the national government, as well as state and local governments, to sponsor pottery making as an art. There is also a pottery experimental station in the Tennessee Valley.
