This year, glass and marble will be the undisputed protagonists of the new edition of Materia Seconda, the third phase of the project inherent to sustainability conceived by BTM and Fucina Frammenti. For the occasion, the exhibition will be accessible to the public in two formats: an exhibition itinerary has been set up within BTM's venues and, for the first time, there is also an installation in an exclusive second venue in Murano, at Manin 56. The reuse capabilities of artistic glass and marble once again place the emphasis on the theme of sustainable innovation. The potential is investigated through the Pièra collection, created for Fucina Frammenti by Matteo Fogale.
