Glass diffuser of Gople lamps is the result of traditional Venetian craftsmanship. For the production, white glass and crystal glass are combined during blowing. This results in the impressive color gradient and makes each Gople glass lamp unique. Silver, bronze, copper and blue finishes are created using an innovative and low-emission metal vacuum deposition process. The finished glass provides beautiful light diffusion. Tip: Use clear or gold filament lamps as illuminants to enjoy particularly impressive lighting effects.
