Hi there everyone! Let’s learn about the History of Vintage purple bottles.
Hope you are having a great week. Today I am sharing some History of Vintage purple bottles. I found these vintage purple bottles last year at a local antique mall. They were not that expensive. The prices varied per size. I think the most I paid for the largest bottle was $6.00. I fell in love with the amethyst and thought it was very unique. I have seen greens, reds and blues but this was a first for me.
I always like to learn something new and thought I would pass that along to you.
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 (Hunter 1950).
