Handcrafted Tiffany Stained Glass Art Each lamp is crafted using the traditional copper foil method, a signature technique of Tiffany lamps. Our artisans cut, shape and weld each piece of stained glass by hand, creating a lifelike red cardinal with vibrant red, orange and yellow hues that glow beautifully when illuminated. The result is a one-of-a-kind piece with subtle variations that make every lamp unique.
