The 16th century was the golden age for Venetian glassmaking in Murano. Major trading partners included the Spanish Indies, Italy, Spain, Ottoman Turkey, and the German-speaking states. At least 28 glassmaking furnaces were in Murano in 1581. Numerous leaders and dignitaries visited Murano during this century, including the queen of France, dukes, princes, generals, cardinals, archbishops, and ambassadors. Collectors of Murano glass included Henry VIII of England, Pope Clement VII, King Ferdinand of Hungary, Francis I of France, and Phillip II of Spain.
