Antique Olive Green Square Glass Bottle Mold Number 782/4

A charming small antique square glass bottle in a deep olive green color. The bottle features a classic applied or tooled lip finish at the top, a square body with gently chamfered corners, and a recessed base embossed with the numbers '782' over '4' - likely a mold identifier. The glass has a rich, dark olive-green tone that appears nearly black in certain light, characteristic of early American or European glassmaking. Tiny bubbles and slight surface irregularities in the glass suggest hand-production or early machine manufacture, consistent with late 19th to early 20th century origin. Approximately 4 to 4.5 inches tall and roughly 1.5 inches square at the base. No label present. No cracks or chips visible. Light surface grime consistent with age. A lovely display piece for bottle collectors or those who appreciate antique apothecary and utility glass.
