I receive a great number of requests regarding pottery marked “OEPIAG” and “EPIAG”. Many wonder why there were so many marks used by them and where these potteries operated. But the facts are both were not individual potteries. Both OEPIAG and EPIAG were acronyms for associations of different potteries put together by the Austrian Government in 1918 to promote the sale of Bohemian pottery and porcelain. The name “OEPIAG” is an acronym for “Österreichische Porzellan Industrie AG,” which translates to Austrian Porcelain Industry. Any pottery with this mark generally predates 1920, when the name was changed Erste Böhemische Porzellan Industrie AG—First Bohemian Porcelain Industry—and the mark was switched to “EPIAG".
