The Italian glass industry dates to the 8th century. In 1291, Venetian glassmakers were ordered to move to the island of Murano to prevent fire from destroying the wooden buildings of Venice. Glass artisans handed down their knowledge and skills through the generations. The Murano artists are forever innovating, and they are known for their use of color and intricate glass decorations.
