{History of Purple Glass} Upon exposure to sunlight, this glass will turn a light pink or lavender to moderately dark amethyst or purple depending on the amount of manganese and amount of ultraviolet (UV) light. This is called “sun-purpled” or “sun colored amethyst ” (SCA) glass.This bottle began its life as colorless glass and has “turned” a much darker than average color of amethyst due to the exposure to (likely artificial) UV light . The light lavender tint produced by manganese offsets the green tint of the iron impurities in sand creating a largely colorless glass.The Venetians apparently discovered by the 15th century that manganese could be used to decolorize glass. Manganese became known as “glass makers soap” due to the ability to “cleanse” or neutralize the effects of other impurities in the sand, particularly iron. ⁣
