Where Does Purple (Amethyst) Sea Glass Come From?
Most softly colored purple ( amethyst) sea glass comes from clear glass that contains manganese and had been exposed to sunlight for several years. The more manganese the glass contains and the more exposure it had to the sun, the deeper its purple hue became.
Glass manufactured with manganese was primarily used for household dishes, cups, bottles, and food containers. Depression glass also came in purple (amethyst) patterns.
The creation of purple glass was discovered accidentally when too much manganese was added to batches of glass intended to be clear in color.
How Old is Purple (Amethyst) Sea glass?
