Antique Root Glass Co. Aqua Blue 32oz Quart Mason Jar with Zinc Cap

Description An authentic antique American canning fruit jar manufactured by the historic Root Glass Company of Terre Haute, Indiana, dating from circa 1906 to 1909. This 32-ounce quart-capacity vessel is made from heavy, wavy glass displaying a vibrant antique aqua blue-green hue.  The front of the body features prominent, crisp embossed lettering in flowing script that reads: "Root" positioned diagonally above a block capital "MASON". The jar is paired with an authentic period-correct zinc screw cap lined with a milky white milk-glass protective seal. Dimensions Capacity: 1 Quart (32 oz) Height: Approximately 7.25 inches (18.4 cm) with lid secured Condition Report True Glass Structural Integrity: The heavy aqua glass body is in excellent antique condition. The perimeter walls, shoulders, and bottom base are free from structural cracks, fractures, or stress lines. True Rim & Threading Assessment: The ground top rim lip and outer helical screw threads are remarkably smooth, showing no jagged chips, large impact dings, or dangerous handling roughness. True Glass Texture & Character: The glass showcases beautiful early machine-age anomalies. This includes a highly defined, prominent seed bubble inclusion on the upper shoulder wall alongside minor elongated air bubbles and light surface waviness trapped within the glass melt.  True Base Details: The underside of the base is molded with concentric circular rings and a distinct central pontil-style glass scar.  True Lid Condition: The zinc metal cap threads onto the glass smoothly and securely. The metal exterior exhibits a heavily oxidized, weathered matte-gray antique patina. The inner milk-glass insert is fully intact and structurally sound without cracks.
