Primary period for manganese's widespread use as a decolourizer to make clear glass.

Manganese glow glass dates from roughly 1880 to approximately 1917,

1880s - ~1917

Unlike uranium glass, manganese glass is not radioactive.

Manganese glow glass, or manganese glass, is any type of glass that contains manganese dioxide and exhibits a fluorescent glow under an ultraviolet (UV) blacklight

The fluorescent colour can vary, appearing green, red, orange, or peach. A softer green glow is common and is often distinguished from the more vibrant "neon" green of uranium glass.

Manganese glass typically fluoresces best under a BLACK LIGHT Manganese glass will glow, often with a subtle green or peachy-orange hue.

Manganese was added to glass to create a wide range of colours, including clear, amethyst, turquoise, orange, and yellow. Clear glass with manganese was often made to imitate crystal. Exposure to sunlight over time can also turn the glass a pale violet or amethyst.

Manganese glow glass dates from roughly 1880 to approximately 1917,

although manganese was also used for decorative purposes in later periods, such as the Art Deco era (c. 1910-1939)

Magnesium glass (magnesium-based crystal) is considered much safer for daily use than traditional lead glass (lead crystal)

While lead crystal is generally safe for short-term consumption, it poses risks of lead leaching, especially with some food and acidic drinks (like wine or spirits) or long-term storage. Magnesium oxide, high-performance glass, is used as a safer alternative to create strength and clarity without the toxicity associated with lead.

Magnesium Glass (Modern Crystal/Glass)

Safety: Considered safe and non-toxic. It is often used as a direct, modern replacement for lead in premium crystalware.

Properties: Magnesium oxide increases mechanical strength, durability, and resistance to thermal shock.

Magnesium glass is the safer choice.
