Antique/Vintage Threaded Glass Bottle

The item is a clear glass bottle, likely an antique or vintage example, characterized by its rectangular body and threaded neck finish. It stands approximately 4-6 inches tall, crafted from clear, colorless glass, though a subtle yellowish or bluish tint might be present due to age or glass composition. The body features four flat panels, ideal for affixing labels, and transitions smoothly into a rounded shoulder before narrowing to a cylindrical neck. The neck terminates in a well-defined threaded finish, indicating it was designed for a screw-on cap, a feature common in bottles produced from the late 19th century onwards. Visible mold lines along the sides suggest machine-made or semi-automatic production methods. The base is square with slightly rounded corners. The bottle exhibits signs of wear commensurate with age, including prevalent interior and exterior cloudiness, minor residue, and a soft patina or sickness on the glass, indicative of contents or environmental exposure over many decades. No major cracks or chips are visible, but surface abrasions are likely. There are no discernible embossed manufacturer's marks, brand names, or volume indicators visible in the provided images. Based on its construction and threading, it is estimated to date from the late 19th to mid-20th century (circa 1880s-1950s). Its utilitarian design suggests it likely contained pharmaceuticals, inks, household remedies, or personal care products.
