Vintage Aqua Glass Square Sauce or Medicine Bottle

This is a vintage 7oz glass bottle characterized by its light aqua or 'green glass' tint and distinct rectangular shape with beveled edges. The bottle features a tall, tapered neck terminating in a reinforced crown-style lip or finish. Constructed using a two-piece mold, side seams are visible running vertically up the body and through the neck, indicating a late 19th to early 20th-century mass-production method. The glass contains numerous small air bubbles (seeds) and slight wavy flow lines, typical of period manufacturing techniques. The interior shows some cloudiness and mineral deposits, suggesting it was once buried or stored with liquid for a long period. No chips or major cracks are immediately visible, though there is minor surface wear and light scratching consistent with age and handling. The base is flat with rounded corners, and while no specific embossed maker's mark is visible on the front, the general form is consistent with condiment, sauce, or pharmaceutical bottles from the 1890s-1920s era. The thickness of the glass at the bottom indicates a durable, utilitarian design intended for reuse or robust shipping.
