Definition of "Crystalline glass"
"Crystalline glass" is defined as colorless and transparent glass, decolored with manganese dioxide, obtained with purified raw materials. Since the Middle Ages, crystal has been considered the most precious Murano glass. The secret of its quality lies in the purity of the raw materials used, in the use of decoloring agents, in the preparation of the vitrifiable mixture and in the conduct of the fusion. In the mid-15th century, the Muranese proposed a pure and colorless glass, which for the first time in history was called "crystal" and was subsequently reproduced in other European countries. Unlike Nordic crystal, which has a high concentration of lead oxide and which today is subject to strict controls relating to fumes from the fusion, Murano crystal is a soda-lime glass whose main components, in addition to silica, are the oxide of sodium and calcium oxide. Soda crystal is very suitable for the production of particularly light blown objects that require long processing times. Towards the mid-1400s, the art of Murano glass experienced an epochal turning point thanks to Angelo Barovier, a fascinating figure as an artist/scientist who managed to obtain, through a real alchemical process, a new type of extremely clean glass so similar in transparency to crystal that he himself called crystalline glass (then Venetian crystal). This new discovery did not succeed in replacing colored glass, which in the meantime had become a peculiarity of Murano production, but it certainly contributed to incredibly refining its transparency.
