Until 1986 Volpriehausen was the location of a family owned glass factory by the name of Buder who produced pressed and mouth blown lead crystal. The factory has been demolished, however there remains a museum and a small cutting shop trading under the name Ludwig who to this day are using blanks produced by Buder.
