More About Goldstone
Legend has it that Goldstone was first manufactured by accident in 17th century Venice. According to this legend, a monk accidentally spilled copper filings into the pure glass being produced in the monastery in which he lived. Horrified by his wasteful mistake, he tossed out the ruined batch of glass and started over. When the ruined batch of glass cooled, its shimmering beauty was noted by fellow members of his order, and a mistake became a happy discovery!
Goldstone is a type of synthetic glass that is heated a very high temperatures and then mixed with copper or copper salts. When the mixture cools, the copper precipitates into small crystalline clusters that sparkle inside the glass.
