Tiffany Glass refers to the decorative glass created by the American artist and designer Louis Comfort Tiffany in the late 19th and early 20th centuries. Known for its vibrant colors and intricate designs, this glass is often used in stained glass windows, lamps, and other decorative objects. Tiffany developed a unique technique called "copper foil," which allowed for more detailed and complex patterns compared to traditional leaded glass. The glass is characterized by its iridescent surface and rich hues, achieved through the use of various metal oxides during the manufacturing process. Tiffany Studios, the company founded by Tiffany, produced many iconic pieces that remain highly sought after by collectors and art enthusiasts today.
