Wall and ceiling lamp with dimmable diffused light. Galvanized metal frame. Borisilicate blown glass diffuser. Light source not included. Two materials: metal and glass, as in the historic tradition of FontanaArte. The metal acts as a base and contains the light source while the glass, the true protagonist of the project, is expertly worked by skilled craftsmen in a process of fusion between a portion of transparent glass and a satin one from which the light diffuses. Fontanella is formed by the union of two glasses: the internal tube is threaded, sandblasted and finally joined with the bubble-shaped blown glass.
