Tiffany glass is a term used to describe the unique style of stained glass created by the artist Louis Comfort Tiffany in the late 19th and early 20th century. While tiffany glass is a widely recognized term, there are also several other terms used to describe this style of stained glass. Some synonyms for tiffany glass include art glass, leaded glass, and opalescent glass. Art glass refers to any decorative glass pieces created by an artist, while leaded glass specifically refers to stained glass made using strips of lead to hold the colored glass pieces together. Opalescent glass is another term used to describe Tiffany's signature iridescent glass, which gave his works a vibrant, shimmering quality.
