Tiffany lamps may mean many things, but most commonly it is the general term for Tiffany style lamps, Tiffany reproduction lamps, and the original Tiffany lamps made by the Tiffany Studios, New York. Original Tiffany lamps are made by the Tiffany Studios New York in late 1800’s and early 1900’s. Tiffany reproduction lamps are reproductions of the original Tiffany lamps. Tiffany style lamps are stained glass lamps inspired by the original Tiffany lamps and other stained glass and Art Nouveau subjects. Stained glass lamps are lamps which shades are made of stained glass (many pieces soldered together). Some stained glass lamps have stained glass bases as well.
