The Ball Brothers' jars, which were produced in half-gallon, pint, and midget sizes, were manufactured during 1884, 1885, and 1886. “Buffalo” jar lids were produced in a Ball Brother metal fabricating factory. The brothers decided to add their logo onto the surface of the glass jars, which were amber or aqua (blue-green) at the time. [3 ...
The initial form of closure for the glass canning jar was a zinc screw-on cap, the precursor to today's screw-on lids. It usually had a milk-glass liner, but some of the earliest lids may have had transparent glass liners. [8] The cap screwed down onto a rubber ring on the shoulder of the jar, not the lip. [10]
The most common configuration is a Mason jar with a flat lid and screw ring. The lid is generally made of plated or painted steel, with an elastomeric washer or gasket bonded to the underside of the rim. The lid also incorporates a slightly dimpled shape, which acts as an indicator of the vacuum (or lack thereof) inside a sealed jar.
The Ball brothers, whose glass company became known for its home canning jars, went into business together in 1880, and made the decision to move their glass manufacturing operations from Buffalo, New York to Muncie, Indiana, in 1886, due to the abundance of natural gas in the area. The brothers opened their factory in Muncie in 1888.
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.
Food is processed in Weck jars using the water bath canning technique, not a pressure canner. During the canning process the lids are secured by the clips which can be removed once the processing is complete and the jars have cooled since the lid is being forced shut by atmospheric pressure.
