How do you identify Steuben glass?

To identify Steuben glass, look on the bottom or interior for a maker's marking. Nearly all pieces produced by the manufacturer display an acid-engraved marking. On glassware produced before 1932, this marking usually consists of a fleur-de-lis and the word "Steuben." After 1932, the maker used many other hallmarks, which you can find images of on trusted online resources. Comparing the marking on your glassware to these images can help you determine if Steuben produced it and approximately when it was made. A certified appraiser or knowledgeable antique dealer can also help you identify the items. Shop a variety of Steuben glass on 1stDibs.
