First the island prospered as a fishing port, and a center for trade, from the 11th century, it began to decline as islanders moved to Dorsoduro, in 1291 all the glassmakers in Venice were forced to move to Murano due to the risk of fires. In the following century, exports began, and the island became famous, first for glass beads and mirrors, "aventurine glass" was invented on the island, and for a while murano was the main producer of glass in Europe.

Murano Glass has not kept pace with production, but is still home to more glass masters than any other single place on earth. The Venetian glass is a type of glass made in Venice (murano) Italy, world renowned for being colorful, elaborate and skillfully made, many of the important characteristics of these objects had been developed by the 13th century.
When the Venetian glass industry moved to murano, Byzantine craftsmen played a role in the development of Venetian glass, an art for which the city is well-known for. By the 16th century Venetian artisans had gained even greater control over the color and transparency of their glass, and had mastered a variety of decorative techniques. Despite efforts to keep Venetian glassmaking techniques within Venice, they became known elsewhere, and Venetian-style glassware was produced in other Italian cities and other countries of Europe.
