Although I usually don't use material which is not natural, I couldn't resist this. Goldstone consist sof minute tetrahedral crystals of copper dispersed in glass. It is created by the melting of glass containing copper salts in a reducing (oxygen depleted) environment, causing the copper salts to decompose to metallic copper. Goldstone has been produced in reddish-brown, blue, purple and green colors; the color of the first is a result of the finely disseminated copper crystals, while the color in the latter three resulting from changes in the body color of the glass. Goldstone was developed by Vincenzo Miotti, a member of a prominent family of Venetian glass makers, in the late 17th century. It was not until the early 19th century, after the family had stopped making glass, that the technique was divulged by one of the surviving members of the family. There are many “urban folklore” mythologies regarding how and when goldstone was created. One claims that goldstone was the result of medieval alchemists’ search to create gold.
