The making of most Tiffany style lamps and reproduction Tiffany lamps follow the tradition of the original Tiffany lamps, by soldering many (often hundreds) of counts of colorful stained glass together. However, please be aware that a small number of Tiffany lamps are made of plastics with glue, or entire glass shades from the mold. These kinds of lamps actually can NOT be called Tiffany lamps, and they have much less value than true Tiffany lamps.
