Goldstone is a man-made glass that was originally manufactured by the Miotti family in Venice, in the seventeenth century. Goldstone is created by warming molten rocks to a suitable temperature enough to break down oxidized copper grains that have been added. The solution is cooled down gently once the copper oxide has been completely evaporated.
