The difference between Tiffany glass and stained glass is that one relates to a brand and the other is a type of glass. Stained glass is colorful glass made by adding metallic oxides to molten glass during the blowing process. Named after Louis Comfort Tiffany who established Tiffany Studios, Tiffany glass involves a technique where copper foil, rather than the traditional lead oxide, serves as the joining material for individual stained glass pieces. Another key characteristic of Tiffany glass is that it often has an opalescent effect that creates variations in color and texture across its surface.

To tell if stained glass is Tiffany, first examine the piece and look for a maker's mark. Tiffany Studios changed its hallmarks many times over the years. By comparing the marking on your piece to images of hallmarks found on authentic items shared on trustworthy websites, you can begin to identify your glass. The base can provide an additional clue if your stained glass piece is a lamp. Many Tiffany lamps have a gray metal ring located under the cap. If you spot one, your piece may be made by Tiffany. Because there are many reproductions on the market, it is often wise to have a certified appraiser or knowledgeable antique dealer assist with the identification process.

To tell if Tiffany glass is Favrile, first check the piece for markings. Many pieces will have the word "Favrile" etched into an inconspicuous area, such as on the base. The iridescent quality of the glass can also be a good indicator of whether or not it is Favrile. However, it can be difficult to identify without experience and training. As a result, you may wish to consult a certified appraiser or knowledgeable antique dealer if you don't locate a Favrile marking on your piece. Shop a collection of Tiffany glass on 1stDibs.
