Try some image searches on variations of phrase: "antique smelling salts bottle" to see if you can spot approximate same color as well as size in round (cylindrical) bottles. I know that quite a few were produced in the same size range, though most were a shade of green that I would call Emerald Green. Contrariwise, I've seen photos of teal green, but usually in a different shape.Found this 1.25” bottle bottom today. Very unusual size and color. Any info on what it was used for and when would be so appreciated.
