You probably have one in your cupboard right now. Maybe it’s holding sourdough starter, or perhaps it’s filled with leftover lentil soup. Most people don’t think twice about the clear glass vessel with the screw-top lid. It’s just a jar. But the mason canning jars history is actually a saga of desperate innovation, failed patents, and a massive shift in how humans survived the winter. Before these things existed, if you wanted to eat a peach in January, you were basically out of luck unless you enjoyed the taste of heavily salted or dried-out leather.
It wasn't just about convenience. It was about not starving.
The disaster before the glass
Before 1858, food preservation was a nightmare. People used "wax seal" tins or crude stoneware crocks. You’d pour hot wax or even lead solder around the lid to keep the air out. It was messy. It was often toxic. If the seal failed—and it frequently did—the food rotted, and botulism became a very real, very deadly guest at the dinner table.
Enter John Landis Mason.
He was a 26-year-old tinsmith from Philadelphia. In 1858, he did something that seems incredibly simple today but was revolutionary at the time: he patented a jar with a threaded neck. This allowed a metal cap to be screwed down onto a rubber ring, creating a literal airtight seal. Mason didn't actually invent the idea of "canning"—that credit usually goes to Nicolas Appert, a Frenchman who figured out heat sterilization for Napoleon’s army—but Mason perfected the vessel.
He made it practical for the average home cook.
Why John Mason died broke
Here is the kicker: despite the fact that his name is stamped on billions of glass jars across the globe, John Landis Mason didn't make a fortune. Honestly, he died in poverty in a tenement house in 1902.

How? His patent expired in 1879.
Once that patent was up, every glass manufacturer in the country jumped on the design. Companies like Ball Brothers and Kerr took his foundation and ran with it, refining the glass quality and the lid styles while Mason's original company struggled to keep up. It’s a classic, albeit depressing, example of how a brilliant invention doesn't always lead to a thick wallet.
The Ball Brothers and the rise of the blue jar
If you’ve ever gone "antiquing" and seen those beautiful, aqua-blue jars, you’re looking at the Ball era of mason canning jars history. The Ball Corporation didn't start in glass; they started making wood-jacketed tin cans for kerosene. When they saw the potential in Mason's design after the patent expired, they moved their operations to Muncie, Indiana.
Indiana was the "it" spot because of the natural gas boom.
The Buffalo, New York-based brothers needed massive amounts of cheap fuel to melt glass, and Muncie had it in spades. The iconic "Ball Blue" color wasn't a stylistic choice—it was a byproduct of the mineral impurities in the sand used at the Muncie plant. People loved it. It became the signature look of American food security for decades.
By the early 1900s, Ball was churning out millions of jars. They weren't just selling glass; they were selling a lifestyle of self-sufficiency. During the Great Depression and through World War II with the "Victory Gardens" movement, these jars were as valuable as currency. If you had a cellar full of filled Ball jars, your family was safe.

The lid evolution: Why we use the "two-piece" today
You might notice that modern jars use a flat disk and a separate screw band. That wasn't the original way. Early Mason jars used a one-piece zinc cap with a porcelain liner to prevent the metal from reacting with the food.
They were a pain to get a good seal on.
In 1903, Alexander Kerr founded the Kerr Glass Manufacturing Corporation. He introduced the "economy" jar which used a disposable metal lid with a pre-applied sealing gasket. This eventually evolved into the two-piece lid we use today. It was a game changer because you could see the "dimple" in the lid pop down when the vacuum seal was successful. That "ping" sound is still the most satisfying part of canning.
Common misconceptions about old jars
- The "Ground" Rim: If you find a jar with a rough, ground-down glass rim, it’s likely from the late 1800s. Manufacturers used to literally grind the top of the jar to make it flat enough for a seal.
- Bubbles in the glass: People think bubbles mean the jar is "special." Really, it just means the glass-making process was a bit crude. It can actually make the jar weaker and more prone to cracking under the heat of a pressure canner.
- Upside-down canning: You’ve probably seen your grandma flip jars upside down to "seal" them. Don't do this. It’s a holdover from a time before we understood modern food safety. It creates a "false seal" that can trap bacteria inside.
Survival and the 21st-century revival
For a while there, in the 1980s and 90s, Mason jars were seen as "kinda old-fashioned." They were things your grandmother kept in a dark basement. The rise of cheap, industrially processed food made the labor-intensive process of canning seem unnecessary.
Then things shifted.
The 2008 recession and the later global pandemic in 2020 saw a massive spike in home gardening and preservation. Suddenly, there was a nationwide shortage of lids. People were scouring eBay for jars. The mason canning jars history isn't just a timeline of patents; it’s a mirror of our cultural anxiety. When the world feels unstable, we go back to the glass.

Beyond food, the jar has become a weirdly polarizing aesthetic symbol. You see them at weddings as cocktail glasses or turned into "shabby chic" soap dispensers. While some purists hate this, it’s probably the reason the Mason jar survived the era of Tupperware and plastic. It’s durable. It’s infinitely recyclable.
Realities of collecting and safety
If you are digging through an old barn and find a "Buffalo" jar or an early "Hero Fruit Jar Company" vessel, you might be sitting on a few hundred dollars. Rare colors like amber, cobalt, or deep emerald are the "holy grails" for collectors.
But a word of caution for the practical users:
Antique jars are great for storing dry beans or pens, but you really shouldn't use them for actual heat-process canning. The glass becomes brittle over time. Micro-fractures you can't see with the naked eye will cause the jar to explode in a boiling water bath. Stick to the modern, wide-mouth jars for your pickles and save the 100-year-old blue glass for the bookshelf.
How to verify your jars
- Check the Logo: The Ball logo has changed dozens of times. A "dropped A" in the Ball script usually indicates a jar made between 1910 and 1923.
- Look at the bottom: Numbers on the bottom aren't "rarity codes." They usually just indicate the mold number or the position on the assembly line.
- Feel the weight: Older glass is often significantly thicker and more "wavy" than the uniform, machine-made glass produced today by companies like Newell Brands (which now owns both Ball and Kerr).
Your next steps for preservation
If you're looking to actually use this history in your kitchen, start small. You don't need a massive pressure canner to get into the hobby.
- Buy a modern kit: Get a basic set of jars from a reputable hardware store. Ensure they are "BPA-free" if you're worried about modern coatings.
- Inspect your rims: Run your finger along the top of every jar. Even a tiny nick will prevent a vacuum seal.
- Use the right lids: Never reuse the flat metal lids. The rubber gasket is designed for one-time use only. You can reuse the screw bands until they rust, but the "flats" are strictly single-use for safety.
- Consult the "Bible": Get the Ball Blue Book Guide to Preserving. It’s updated constantly with the latest USDA safety guidelines.
The Mason jar isn't just a hipster icon or a relic of the past. It’s a tool of independence. Understanding where it came from helps you appreciate the fact that you can keep the harvest of August fresh until the following July. That’s a type of magic John Mason would be proud of, even if he never got his paycheck.
