Vintage Stolzle Glass

To identify vintage glass, you will need to figure out if your item is between 20 and 99 years old. The easiest way to do so is first to determine the maker by looking for and then researching any markings present on the glassware. Unfortunately, vintage glass is often marked with paper and foil labels, which tend to come loose with use. As a result, experience and expertise are often necessary to accurately perform the identification process, so you may wish to have a certified appraiser or experienced antique dealer weigh in if your glassware is unmarked.

To tell if your vintage glasses are gold, look on the nose bridge and the temples for a purity mark. Makers often stamped their solid gold pieces with “12K,” “10K,” “14K” and other markings to identify their gold eyewear. You can research all of these markings using trusted online resources. Should you locate a "GF" mark, it is likely that your glasses are gold-filled rather than solid gold. This means that the frames are predominantly a less expensive metal but do have a thin layer of genuine gold alloy as a finish. Another mark that indicates your glasses contain some gold is "RGF." The mark stands for “rolled gold filled.” Glasses bearing this mark feature a gold-plated finish that is thinner than what's found on traditional gold-filled frames. For assistance identifying your eyeglass frame material, consult a certified appraiser or experienced antique dealer. Explore a selection of vintage glasses on 1stDibs.
