White sea glass (naturally frosted glass fragment)

Man-made silicate glass, typically soda-lime glass; not a mineral or rock

AI-generated identification · may be incorrect

Translucent, pale gray-white, with a smooth, matte surface from abrasion; glass is amorphous and has no cleavage. Hardness is about 5–6 on the Mohs scale; specific gravity is roughly 2.4–2.8.

Physical properties

Translucent, pale gray-white, with a smooth, matte surface from abrasion; glass is amorphous and has no cleavage. Hardness is about 5–6 on the Mohs scale; specific gravity is roughly 2.4–2.8.

Formation & geological history

Likely discarded glass weathered by waves, sand, and time; its age and exact source cannot be determined from the image. It is human-made, not a geological formation.

Uses & applications

Collected as beach-found decor or used in crafts and jewelry; the pictured piece rests on a cork coaster.

Geological facts

Sea glass becomes frosted as repeated abrasion pits and smooths its surface. The surrounding brown square appears to be cork, not part of the specimen.

Field identification & locations

Its rounded, frosted surface and uniform glassy translucence distinguish it from most natural minerals. Sea glass is commonly found on beaches near historic settlements and dumping sites.
