Lids for home canning
Everyone loves Mason jars. But how do you know? Luckily, there are experts out there who can tell you all about the different types of Mason jars that have appeared — and disappeared — through the ages. And what are Mason jars, anyway? The glass jars were created to form a hermetic seal, and were used for canning and jarring.
The two-piece metal Mason jar lid system is also referred to as a “self-sealing lid Gaskets in unused lids work well for at least 5 years from date of manufacture.
Remember when the mason jar was actually a breakthrough in the American way of life? How the revolutionary new threaded lid offered an alternative to pickling, drying and smoking as ways to preserve our precious aliments? Yes, the mason jar certainly harkens back to a simpler time, before refrigerators and artificial preservatives, and now that we take those things for granted, canning has become something of a throwback jam cue snare —the vessel once dedicated to keeping and storing foodstuffs is now commonly used as a drinking glass or decorative object.
Not that there’s anything wrong with that: Unlike, say, the Edison bulb, the design of the mason jar has virtually no room for improvement, and its timelessness is certainly part of its appeal—as an object, it is imbued with nostalgia, thrift and if you’ll excuse another terrible pun a can-do attitude. Of course, the canning jar didn’t come out of the blue though we’ll see that the color has some significance , and its current mass-produced form was refined over the course of several decades in the latter half of the 19th-Century.
The tinsmith’s innovation was to create a seal inside the lid, as opposed to attempting to make a lid that was flush with the jar: glassmaking techniques of that era allowed for rough threading, but the tolerance wasn’t nearly accurate enough to create the airtight seal needed to preserve perishables. By grinding the lip of the glass until it was nearly flat known as a ‘square shoulder’ and inserting a simple rubber gasket inside the lid, Mason achieved a sufficiently airtight seal, and his namesake was born.
The Ball Corporation—which also provides funding for the eponymous state university—was among the companies that capitalized on Mason’s invention when the patent expired. Although the vessels were made of tin, the cans were lined with a glass container to prevent corrosion. With the help of two of their brothers, they quickly expanded the glassmaking operation and decided to produce canning jars, for which Mason’s patent had expired in When Frank heard about the natural gas boom in Indiana in , they decided to relocate to Muncie the fifth brother, Lucius Lorenzo, was a practicing physician prior to joining his siblings in

Image courtesy: flickr. They have been re-appearing in flea markets, groceries, home shops, you name it. People have been rummaging in their attics and cupboards hoping to find these items not only to join the fad. Very rare mason jars have recently fetched up to a thousand dollars, while antique ones can be priced for up to a couple of hundreds online.
The interesting part here is, the older they are, the rarer they get, the more expensive they can be. Just like wine, mason jars that have been produced at a certain time period may cost more. But even before we talk about that, what are mason jars really? Mason jars date back to the s when John Landis Mason thought of an innovative way to seal jars. Before his patented invention, glass jars were sealed with a thin lid glued together by wax.
This proved to be a difficult task especially when resealing the jars because lids cannot be reused. Landis introduced a lid that can be tightened by a screw ring. He was unable to takeoff from this though until the Ball Brothers caught up with this idea in in Muncie, Indiana. From then on, the Ball brand of mason jars have taken over the market by storm making it a common household item. The popularity of mason jars continued to soar during World War II, when the US government asked its citizens to grow and preserve their own food.

A Mason jar — named after John Landis Mason , who patented it in — is a molded glass jar used in home canning to preserve food. The jar’s mouth has a screw thread on its outer perimeter to accept a metal ring or “band”. The band, when screwed down, presses a separate stamped steel disc-shaped lid against the jar’s rim. An integral rubber ring on the underside of the lid creates a hermetic seal. The bands and lids usually come with new jars, but they are also sold separately.
While the bands are reusable, the lids are intended for single-use when canning. Largely supplanted by other products and methods for commercial canning, such as tin cans and plastic containers, glass jars and metal lids are still commonly used in home canning. They are produced in a variety of volumes, including cup half-pint , pint , quart , and half- gallon. In home canning, food is packed into the Mason jar, leaving some empty “head space” between the level of food and the top of the jar.
The lid is placed on top of the jar with the integral rubber seal resting on the rim. A band is screwed loosely over the lid, allowing air and steam to escape. The jar is heat sterilized in boiling water or steam and the lid is secured.

Canning lids do have a shelf life. I am talking about unused lids in the box. Not lids on jars. I’ve seen it recommended that you not buy more than what you will use in a year. But then I’ve also seen that lids will be good for 5 years. Seems like they contradict, right? The gasket compound in older unused lids may fail to seal on jars.
Buy only the quantity of lids you will use in a year. But don’t buy too many. You might as well not push that date. One years supply is pretty good but if you go over certainly don’t throw your lids away. Then you’ll have the situation where you don’t really know how old the lids are but you are pretty sure you are within that 5 year range.

Here is a way to date your Ball jars fairly closely by looking only at how the Ball name is embossed on the jar. Before we get into the Ball jars, here’s just a note concerning “Pontil Marks”. I see a lot of jars listed on ebay incorrectly with pontil marks. NO jars were ever made that had pontil marks. The approximately 1″ circular mark seen on the bases of some early Ball jars indicates machine manufacture and is a VALVE mark, which let air trapped between the mould and jar to escape during production.
There are only a FEW very early fruit jars which have pontil marks, and these have an applied lip of some kind. There was no need on any of the screw lid type jars for attaching a punty rod to the base of the jar which creates the pontil mark because the thread area and lip was created in the mould when the jars were made. Ball first started making jars in in Buffalo, New York. There are three basic types known and these are called the “Buffalo” jars. Shortly after their move to Muncie and new plant startup in , Ball was making Mason’s Patent Nov.
