Physical properties
Hardness: 5.5-7 (Mohs), Color: Light Green (common), Luster: Frosted/Vitreous, Crystal Structure: Amorphous (non-crystalline), Cleavage: None (conchoidal fracture), Specific Gravity: 2.4-2.8
Formation & geological history
Formed from physically and chemically weathered shards of manufactured glass in ocean environments over many years.
Uses & applications
Used in jewelry making, crafting, and collecting.
Geological facts
Light green sea glass often comes from old soda bottles (like Coca-Cola) or vintage wine bottles.
Field identification & locations
Identified by its frosty appearance and smooth, rounded edges. Commonly found on beaches worldwide where glass debris has been historically dumped or washed ashore.
