Physical properties
Olive-green, translucent, glassy luster, with irregular sharp fracture; hardness about 5–6 Mohs. It is amorphous, with no crystal structure or cleavage.
Formation & geological history
This appears to be a fragment of melted, human-made glass rather than naturally formed rock or mineral. Its age and source cannot be determined from the image.
Uses & applications
Bottle glass is used for containers and can be recycled; this fragment has little value as a collectible.
Geological facts
The irregular curved edges and uniform glassy appearance are typical of broken glass.
Field identification & locations
Green glass can resemble obsidian, but bottle fragments often show curved fracture surfaces and consistent coloration. Estimated value: under $1.
