Murano glass is mainly composed of very pure silica sand which takes any desired colour with the addition of common or rare metal oxides.
This compound, with small amounts of other chemical materials, is fused at a very high temperature then turning into coloured glass.
Each color is characterized by a different oxide that, proportionally to the amount used, determines its intensity.
Murano since ancient times preserves the secrets of colored glass made in its furnaces.
