The Aventurine glass is a special process invented in Murano in the first half of the seventeenth century (1620).
It is a translucent crystalline dough, in which are immersed specks or copper crystals with brilliant metallic oxides, which create an effect that mimics that of aventurine quartz.
The process involves adding, at the end of the fusion, and in most locations, in a specific amount of iron typing, silicon metal or coal, all reducing raw materials.
