Favrile is a type of iridescent glass developed by the American artist and designer Louis Comfort Tiffany in the late 19th century. Favrile glass is characterized by its unique combination of colors, textures, and shapes, which create a beautiful, shimmering effect. The name Favrile is derived from the Latin word for 'hand-made, ' which reflects the craftsmanship that goes into creating this type of glass. Favrile glass is often used in stained glass windows, lamps, and other decorative objects.
