Despite all our efforts, not all production waste can be recycled and, therefore, reused. Murano-glass is an example; it cannot be recycled with normal glass because of the chemical elements used to colour it. Therefore, Murano-glass waste must be processed as “special waste”, and this is a big economic and environmental issue for the whole Murano activities. How can we change this situation? Is there a way to produce new Murano glass objects by locally reusing the waste from glass-factories? Ghebo tries to answer these questions. It aims to investigate the universe of new technologies to understand how to integrate them with glass craftsmanship. The collection is an experimental path that combines the tradition of the Murano glass making with the most advanced digital manufacturing technologies, creating a link between past and future. It is also the first collection in the World made by 3d printed glass-waste using a room-temperature process. Thanks to this innovative 4.0 craftsmanship technique, the glass-waste from Murano glass factories is transformed into a ‘glass paste’ that can be shaped (3d printed, in this case) at room temperature. Also, the shape of these objects, has been generated by a digital algorithm optimized to simulate a geometry in constant change, a shape that takes inspiration from the sinuous curves of Venetian lagoon velme and ghebi.
