History of Glass Door Knobs:
By 1920, doorknobs made from crystal and cut glass were widely manufactured and sold.
Most of the antique and vintage glass knobs manufactured were clear, and colored glass was used less frequently. Cobalt, red, Lavender and Vaseline glass knobs are the most prized colors for antique and vintage knobs. When exposed to sunlight, some pieces of clear glass will gradually turn purple. What causes some glass to turn purple? The answer lies in the presence of a little-known element: manganese. Radiation from the sun will cause manganese to oxidize. Glass exposed to sunlight for a long period of time will turn purple if it contains manganese. However, glass that contains manganese that is not exposed to sunlight, UV light or other forms of radiation will retain its clear appearance.
