The origins of cranberry glass making are unknown, but many historians believe a form of this glass was first made in the late Roman Empire. This is evidence by the British Museum\'s collection Lycurgus Cup, a 4th-century Roman glass cage cup made of a dichroic glass, which shows a different colour depending on whether or not light is passing through it; red (gold salts) when lit from behind and green (silver salts) when lit from in front.The craft was then lost and rediscovered in the 17th century Bohemian-period by either Johann Kunckel in Potsdam or by the Florentine glassmaker Antonio Neri in Italy.But neither of them knew the mechanism which yielded the colour. Chemist and winner of the 1925 Nobel Prize in Chemistry Richard Adolf Zsigmondy was able to understand and explain that small colloids of gold were responsible for the red colour.The most famous period of cranberry glass production was in 19th century Britain during the Victorian Era.Legend holds that cranberry glass was first discovered when a noble tossed a gold coin into a mixture of molten glass. This legend is almost certainly not true, as the gold must be dissolved in aqua regia before being added to the molten glass.
