Lightning fruit jars, another type of Mason jar, were not as common as the screw-thread version, but they were popular for home canning in the late nineteenth and early twentieth centuries. They are also produced in a variety of volumes, including cup (half-pint), pint, quart, and half-gallon. Jarden Corporation, based in Boca Raton, Florida, In home canning, food is packed into the 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.If you can your own fruits and vegetables, you might be surprised to find that the value of old canning jars is often significant.If you are using the ones your grandmother left you, that jar of spiced peaches might be worth more than you think.The band, when screwed down, presses a separate stamped aluminium disc-shaped lid against the jar's rim.An integral rubber ring on the underside of the lid creates a hermetic seal.I did a little shopping this weekend at my favorite antique and “junk ‘in” spots! Would you like to know how old your vintage mason jar is? – because some thought the fancy loop at the end looked like a third L. After doing some research online, I found that these are probably one of the earlier sets of Ball jars to be manufactured.
The Self Sealing jar was one of the first products that the company released.
The script style was that of a cursive Ball with an extra loop at the end, known as “3-L” Ball jars.
They also continued to make the MASON’S PATENT NOV 30th 1858 jars (machine made smooth lipped varieties) up into the early 1900’s.
Here’s the section of their site that describes the ones I found.
About 1895, Ball began using machines (these jars have smooth lips) and began to phase out the old blowing methods. The machine made jars exhibited a new script style which was never seen on any of their handmade jars.
The bands and lids usually come with new jars, but they are also sold separately.
