The documentary is about one of the most useful and used materials by man: glass. Millennia of human history are linked to this material, starting from obsidian, up to the most elaborate contemporary objects; in between there is everything. This documentary offers a full immersion in the history of the Italian glass, using Venice (Murano), as the ideal sample since it represents all of what has made this art an Italian excellence. This documentary will be a real journey across the history of glass craftsmanship, from antiques to the most modern creations.
