In 1902 a failing glassworks was acquired by Arnošt Pryl, and it was named Rosahütte after his wife Ružena. In 1903 the glassworks burned down but Pryl rebuilt on the same site a more modern glassworks, with an expanded capacity and the glassworks was called "The Rose". They made high quality glass, and between 1905-1907 this was exported to the USA, England, France and Spain. Their output included both engraved and painted* glassware.  Post-war Pryl employed glassmakers from the Heralec glassworks (Grossman, and Palme Konig) which did not reopen after the war. Operation of the glassworks was not interrupted during World War II but after WW2 it was nationalised and switched to producing scientific borosilicate glassware.
