Muranese glass art, like other craft techniques, combines multiple aspects within the practice: sensitive use of the raw materials, observation and attention for skills and careful and measured production. All ingredients for a sustainable process. The initial investigation into the process of the waste started by removing the cotisso (main glass production residue) as it’s only partially recoverable, by melting it again. The galotta, also known as the top of the blown glass product, was definitely more interesting as it could be considered noble waste. It is a necessary part of the mould as it facilitates blowing, but is then removed for the functional needs of the product. The galotta has the same characteristics as the glass from which it’s divided, and therefore, it keeps the same dignity and value when reused. As a result of this concept, a collection of four lamps has been designed, and it represents the value of reducing waste in the glass production cycle. The galotte’s retrieval from the Murano glassworks has been possible thanks to the advice of BTM Officina.
