Things You'll Need
Instructions
Refer to a glass encyclopedia to identify your glass vase. Online encyclopedias, as well as traditional books, are available. The encyclopedia will contain photos of various styles of glass from all time periods and identify different designers. The encyclopedia will also have information on trademarks that specific designers used to identify their work. Use the encyclopedia to assess your vase and track the possible designer.
Attend glass fairs. Because these events specialize in glassware, the merchants and collectors there will be knowledgeable about glass. Ask these people questions regarding glass vases to gather more information.
Ask a glass expert to identify and evaluate your glass vase. Contact an expert at a museum or glass guild and ask for an evaluation on style, time period and value of your piece.
