In the wall lamp, designed by Gae Aulenti and Piero Castiglioni in 1980, three different types and processes of glass coexist in a single object: blown, natural and natural crystal. It represents an exemplary model of technical integration between craftsmanship and industry. The light emitted is diffused and, through a dimming system, the light intensity can be adjusted. The diffuser is made of glossy blown glass, colored in the paste. The wall support is instead in nickel-plated brass.
