Sibilla was designed by Crepax & Zanon to create a beautiful dance of light in your space. The unique texture of the glass is created during the glassblowing session when the glass maestro dips the hot glass into water and causes the glass to rapidly shrink. This causes a dense network of cracks to form on the surface. Immediately after, the maestro gently warms the glass back up to maintain this pattern on the glass and assure the structural integrity of the glass. This traditional technique is called craquel or ghiaccio and result is a unique ripple pattern that is left frozen in the glass and creates an unique play of shadow and light on your walls. Sibilla is available in two sizes. Each is unique and handcrafted in Italy.
