ES Germany porcelain was made at the factory of Erdmann Schlegelmilch from 1861 to 1937 in Suhl, Germany. The porcelain, marked ES Germany or ES Suhl, was sold decorated or undecorated. Most of the porcelain with the ES Germany mark is from the late 1890s or from about 1902 to 1938. Other pieces were made at a factory in Saxony, Prussia, and are marked ES Prussia. Reinhold Schlegelmilch also made porcelain. There is no connection between the two factories. Porcelain made by Reinhold Schlegelmilch is listed in this book under RS Germany, RS Poland, RS Prussia, RS Silesia, RS Suhl, and RS Tillowitz.
