Metal oxides have been pivotal in the art of Murano glassmaking, providing vibrant colors and intricate decorations.
Metal oxides are essential in Murano glassmaking for adding color to the glass mass or creating enamel colors for surface decoration. These oxides are suspended in an oily medium to facilitate application with brushes, and the final color is achieved through heating and firing.
Commonly used oxides include antimony, cobalt, copper, iron, and manganese, with others like chromium, gold, nickel, selenium, silver, titanium, and uranium also employed. Tin oxide serves as an opacifying agent. The resulting colors depend on the glass's nature, ingredient purity, furnace conditions, heat level, and reduced atmosphere conditions (oxygen deficiency).
