Vintage "Root Mason" Canning Jar with Metal Lid

This is a vintage "Root Mason" canning jar, characterized by its distinctive aqua or light blue-green tint, a common color for glass canning jars from the late 19th to mid-20th century. The jar appears to be a quart-sized (or potentially a smaller pint-sized) vessel, held comfortably in an average adult hand. The glass itself is thick and robust, exhibiting some minor surface irregularities and bubbles, which are indicative of older manufacturing processes and add to its antique charm. Embossed prominently on one side in a raised, stylized script is the word "Root" over the word "MASON" in sans-serif capital letters. These markings are clear and well-defined. The jar features a threaded neck designed to accommodate a screw-on lid. The accompanying lid is a two-piece type, typical for canning jars, with a threaded metal band and what appears to be a metal insert (though only the band is clearly visible). The lid exhibits a noticeable dark, oxidized patina, consistent with age and exposure, suggesting it is likely made of zinc or a similar metallic alloy. There are no apparent cracks or significant chips in the glass, and the overall condition suggests it has been well-preserved, though its exact age is hard to determine without more specific manufacturing marks (e.g., on the base). This type of jar was primarily used for food preservation but is now widely collected for its aesthetic appeal and historical significance.
