In 1291, all glass blowers from Venice were forced to move to Murano because of the fire risk. It was also said that the intention was to better protect the secrets of glass blowing. In the end of death, glassblowers were forbidden to tell their art; These people lived as prisoners on the island. Murano became famous for the glasswork and also the mirrors. Murano also invented the Aventurian glass. Later the island became famous for its candlesticks. 

In the eighteenth century, industry declined due to the glass art in Bohemia. But at the beginning of the twenty-first century, glass is still the most important industry in Murano.
