A complete Mason jar is composed of a tempered glass jar, a flat self-sealing lid, and a metal band. [20] The jars are made with either a wide mouth (3 inches (76 mm)) or regular mouth (2 + 3 ⁄ 8 inches (60 mm)) opening. They come in a variety of sizes, from 4 ounces to a gallon.
John Landis Mason (c. 1832 in Vineland, New Jersey – February 26, 1902) was an American tinsmith and the patentee of the metal screw-on lid for antique fruit jars commonly known as Mason jars. Many such jars were printed with the line "Mason's Patent Nov 30th 1858". [ 1 ]
A jar is a rigid, cylindrical or slightly conical container, typically made of glass, ceramic, or plastic, with a wide mouth or opening that can be closed with a lid, screw cap, lug cap, cork stopper, roll-on cap, crimp-on cap, press-on cap, plastic shrink, heat sealed lidding film, an inner seal, a tamper-evident band, or other suitable means.
Jars are commonly in either pint or quart capacities, with two opening diameters, known as "standard" and "wide mouth". When a jar has cooled and is properly sealed, pressing the dimple on the lid will not make any sound. An improperly sealed jar will allow the dimple to move up and down, sometimes making a popping noise.
Hazel Atlas glass plants in West Virginia included one along the Tygart River in Grafton (1916–60) that largely produced wide-mouth canning jars, and the world's largest tumbler factory in Clarksburg (1902–87). By 1920, the Clarksburg factory had 15 acres of floor space, employed 1,200 people, and shipped all over the world.
Prior to 1933, Ball was the largest domestic manufacturer of home canning jars. In 1939 it manufactured 54% of all the canning jars made in the US. A drop in demand for the jars during the 1930s led the Ball brothers to begin manufacturing other types of jars and bottles for commercial use, and eventually expanding into other lines of business.
