The Venetian glassmaking family Miotto is still known today. Around 1626, they discovered the secret of how to produce sparkling, colored decorative glass from initially colorless glass by adding metal compounds. The exact production process was passed down from father to eldest son in the Miotto family
eldest son until it was forgotten due to the political unrest in Venice at the end of the 18th century. In the second half of the 19th century, the production process for Gold stone was rediscovered by the German chemist Max von Pettenkofer. Glassworks in Bavaria and Bohemia soon began producing sparkling Gold stone. To this day, Gold stone is still widely used in the production of jewelry and handicrafts.
The best-known variant of Gold stone is brown Gold stone, the color of which comes from tiny copper crystals that form during the special manufacturing process in the molten glass. For brown Gold stone, the glass mass is first melted from quartz sand and other silicate raw materials as well as copper oxide and other metal oxides, then the metallic copper is produced by chemical reduction in the melt. In the absence of air and through very slow cooling, fine copper crystals can form in the melt, which later trigger the glitter.
In addition to the term "Gold stone", "aventurine glass" is also known. This is derived from the Italian term "per avventura" - by chance - which refers to the distribution of the crystals that cannot be precisely determined.
