We have little information on Franz Grosz and his company Groszart. He was an artist who worked in a variety of media, including glass. He did not work for a glass firm, but purchased blanks (glass with no pattern or decoration), which he decorated by a process he called sandcarving. Although we have two catalogs of his ware, it is all smaller objects - tableglass, vases, etc., and no large pieces. He often sold his glass through a firm Mary Ryan. In 1951, the firm was in Elmhurst NY and was owned by Joseph F. Grosz and Robert Bodkin, and listed themselves as "decorators of glass for giftware and decorative architectural purposes".
