The bottle was produced from manganese-bearing glass, which later transformed to a deep amethyst hue when irradiated. It features authentic early manufacturing details, including faint seam lines, small air bubbles, and notable iridescence from age. Once a utilitarian dairy vessel, it now stands as a striking decorative collectible celebrating the beauty of early glass chemistry and industrial design.

The Steubenville Pure Milk Co. operated out of 421 Washington Street in Steubenville, Ohio, and is documented in city historic records as a locally-owned dairy business in the early 1900s, under proprietor Carl Mildner. Their embossed one-pint bottles, such as this example, reflect the era’s direct-to-consumer milk distribution and now attract interest from regional bottle collectors thanks to their identifiable branding and local provenance.
