*Glass produced in Venice and the surrounding area from the 10th century. In 1292 most Venetian glassmakers moved to the island of Murano in the Venetian lagoon. By the end of the 16th century 3,000 of the inhabitants were involved in the industry, forming a tight-knit, secretive community. During the 15th century they had developed cristallo glass, which was very clear and could be blown into fine and elegant shapes of fragile appearance. Other techniques which the Venetians developed were millefiori (a thousand flowers), an arrangement of coloured glass canes; latticino, lacy inclusions of coloured glass; and reticello, filigree glass. The growth of glass industries elsewhere and the invention of lead crystal glass in England in the late 17th century led to the decline of Venetian glass. A successful revival began in the mid-19th century, when the Salviati glass house and others imitated the earlier fancy glass designs. In the 20th century Venini created unusual, modern designs which show the original qualities of Venetian glass.
