Sea glass (likely green bottle glass)

Human-made soda-lime silicate glass; not a natural mineral or geological rock

AI-generated identification · may be incorrect

Translucent pale green, frosted and smoothly rounded, with no visible crystals or cleavage. Glass has no Mohs hardness rating comparable to a mineral; typical bottle glass is about 5–6.

Physical properties

Translucent pale green, frosted and smoothly rounded, with no visible crystals or cleavage. Glass has no Mohs hardness rating comparable to a mineral; typical bottle glass is about 5–6.

Formation & geological history

Formed by melting silica sand with soda and lime, then shaped industrially; the piece was likely weathered and abraded in water for years. It is not a geological-age specimen.

Uses & applications

Collected as beach glass and used in crafts, jewelry, and decoration; ordinary pieces have little commercial value.

Geological facts

Its frosted surface and rounded edges result from prolonged abrasion and chemical etching, unlike naturally formed crystals.

Field identification & locations

Look for a uniformly glassy interior, curved fracture surfaces, and a pitted or frosted exterior; common on beaches near historic glass disposal sites.
