The beautiful amethyst or purple color of this glass is a result of the presence of manganese in the glass, which was a decolorizer to turn the glass clear. Glass that contains manganese, when exposed to ultraviolet rays of the sun or other sources of UV rays, causes the glass to turn amethyst. Some of my amethyst bottles and glass are purpled from years of exposure to natural sunlight. Others have been purpled with the use of strong UV lights in a box…and some have been purpled by running them through a water sterilization plant, which is a safe and permanent process which does the same thing as many years of exposure to natural sunlight, except much faster. To those "purists" who falsely believe that glass cannot turn this deep amethyst color naturally, I could take you to places where bottles and glass have turned this same shade of purple from being in the sunlight for many years
