Confetti glass is one of the innovative physical manipulation techniques that Louis Comfort Tiffany and his craftsmen perfected in their glass furnaces in Corona, Queens. This technique was crucial to Tiffany's philosophy of "painting with glass" rather than on glass, thereby eliminating the need for paint.
The Production Process of Fractured Glass
To produce confetti glass, thin bubbles of glass were blown until they were paper-thin and shattered into thousands of irregular shards. These colorful shards, the 'confetti', were then scattered onto a still-hot, molten glass sheet, often on an iron table, and rolled flat. The shards were thus pressed into the underside of the glass and fused into it.
Application and Aesthetic Effect
The result is glass that refracts light in an unpredictable and vibrant way and possesses a visually complex, layered structure. This layered structure was perfect for simulating the natural variation of the outside world. Tiffany Studios often used confetti glass in its landscape windows and lampshades to create the illusion of dense foliage or to mimic the texture of distant leaves.
Confetti glass demonstrates the synergistic combination of artistic demands and chemical control that distinguished Tiffany Studios. It was among the range of specialized glass types—along with drapery glass and streaky glass—that Tiffany developed to capture the complexity of nature as faithfully as possible.
