When I recently did some organizing of my supplies, I was a bit surprised at the sheer number of canning jars I had placed into boxes.  By the time I got to the 20th box, I admitted to myself that I am clearly a canning jar hoarder.  That said, I don’t think I am in need of an intervention. Yet.  On the contrary, I think everyone should own more versatile and beautiful canning jars.

Canning jars, also commonly referred to as Mason Jars, have a long and colorful history.

The History of Canning and Canning Jars

Canning as a method of preservation was first created during the time that Napoleon was in charge of the French Army. The army wanted a way to preserve food so that soldiers could be better nourished.  The military offered a prize of 12,000 francs to the person who could come up with a solution to this issue.

It took 15 years for the prize to be awarded. After years of experimentation, Nicholas Appert, a Parisian candy maker, and chef won the prize in 1810 for his invention.  The same year, he published the first book of food preservation, called  L’Art de conserver les substances animales et végétales (or, in English, The Art of Preserving Animal and Vegetable Substances which you can view and download for free).

In the early 1800s, however, most people could not afford glass jars for food preservation, so they continued with their traditional methods until the Civil War, when John Mason invented the “Mason jar” with a reusable lid. Because of his ingenuity, to this day, many of us still refer to canning jars as “Mason jars” regardless of the brand.

Canning reached an all-time high during the 1940s when the government declared canning the contents of your victory garden to be a wartime obligation. At that time, over 75% of American families preserved food by canning it, and over 12 million gardens had been planted across the country.

Once the war was over, however, people returned to shopping at the grocery store, and the number of people who canned dropped and has continued to do so. Recently, though, as more people seek self-reliance due to climbing prices and terrible selections at the store, canning has experienced a bit of a renaissance and jars are back in style.

The Different Types of Canning Jars

The thing that makes jars so darned addictive is that they are as useful as they are lovely. Some antique jars come in shades of aqua, and some modern jars are available in blue, green, and purple.

Of course, one of the most frequent uses for jars is home preservation.  Not only can you preserve pickles, jams, and jellies, but you can branch out into pressure canning to preserve low-acid foods like meats, vegetables, and entire meals. (If you are like me and have not yet gotten up the nerve to try pressure canning, read this! I guarantee you’ll be ready to take the plunge.)

Whatever you’re preserving, you need to choose the right jar for the job. Not only do jars come in different colors, but they also come in all sorts of shapes and sizes. This handy infographic can help.

How else can you use canning jars?

Canning jars are good for a lot more than just food preservation, though. They can also be used in some of the following ways:

Straight shouldered jars can be used to freeze food – just be sure to leave room for expansion.

Store leftovers in them instead of BPA-laden plastic containers.

They make charming, country-style vases for flowers from the garden.

Wide mouth jars make quirky drinking glasses.

Fill a half pint jar with water for a floating candle. You can add food color to the water to make it match your decor.

Store dried foods in them. Use a Foodsaver Vacuum Sealer Jar Attachment to remove the air for long term storage.

Store cutlery in them on the counter – tie some ribbon around the jars to coordinate with your kitchen.

Paint a square on them with chalkboard paint so you can write the name of the food you are storing in them.  You can also purchase chalkboard labels for the lids.

If you purchase herbs in bulk (or harvest them from your garden) you can store the dried herbs in a canning jar.

Use smaller jars for sewing notions or small craft supplies.

Pour your own jar candles in them.

Store candy in them for an old-fashioned, decorative holiday display.

Glue coarse sandpaper to the lid and store matches in it for a water resistant container with a strikeable top.

And a bunch of other stuff!

Change up the lids and do neat stuff with your canning jars.

Of course, the nifty lids that are now available take the versatility of canning jars to a whole new level. Check out some of these tops you can get to make your jars serve different purposes:

These lids have a hole in them for straws, making this the perfect beverage container for outdoors:  Ball Wide Mouth Mason Jar with Sip and Straw Lids

These lids have a pour spout for easy dispensing of whatever dry item you’ve stored in the jars:  reCAP Mason Jars Pour Cap

And these lids have a spout for dispensing liquids:  Magnuson mason jar pouring spout, regular size.

These lids have cutouts. You can use them to hold scented items like potpourri, or you can use them to hold a homemade baking soda-based cleaning powder:  Pewter Daisy Cut Out Lid for Mason Jars

These chalkboard lids can be used for labeling the contents of the jar: Chalk Tops – Reusable Chalkboard Lids for Mason Jars

These lids turn your jars into fermenting units: FARMcurious – Mason Jar Fermenting Kit

This lid is a soap or lotion dispenser. Mason Jar Soap/Lotion Dispenser Lid black

This converter top turns a mason jar into an oil lamp:  Mason Jar Oil Lamp Burner Chimney Holders Turn Mason Jars Into Nostalgic Oil Lamps

And finally, these lids turn your jars into adorable and useful little solar lanterns, either hanging or tabletop:  Hanging Solar Lid Light or Hanging Solar Lid Light

How do you use your canning jars?

I am a total canning jar addict and other than finding a 12 step program, will probably continue to hoard them as I see them on sale.  Finding additional uses is not an issue plus, later this summer when there is an abundance of fresh produce available, I plan to do some real canning and pickle making.

Are you a canning jar addict too? How do you use your jars other than canning in them?

The Final Word

A special shout out goes to Tiffany at who gave me permission to share her infographic.  In her own words, her blog is about her “personal experiment to thrive in all areas of life (physically, mentally, spiritually).”  You might want to pay her a visit.

Thanks, Tiffany!

Enjoy your next adventure through common sense and thoughtful preparation!

reCAP Mason Jars Pour Cap: Of all of the various types of lids you can get for canning jars, this is my favorite.  I use one for laundry soap and another for syrup. These are great.

Mason Jar Storage Caps Set of 8: These are fantastic!  These plastic lids screw onto a mason jar and are perfect in the pantry or to cap you homemade salves.  There is both a regular and a wide mouth version.  I add chalk labels to the top and am all set.

Chalky Talky 40 Regular or 36 Wide Mouth Mason Jar Lid Reusable Chalkboard Canning Labels:  These are terrific and are totally reusable.  Don’t forget the chalk markers if you do not already have some.

Ball Jar Heritage Collection Pint Jars in Blue, Set of 6:  2013 marked the 100th anniversary of the first series of jars designed by Ball brothers, each jar intended to be better than the one before. These limited edition jars are a celebration of the heritage featuring period-correct blue color and embossed logos on the front and back. Gorgeous.

Ball Heritage Collection Pint Jars in Green, Set of 6: Same as above but in green.  Note that these colored jars also come in quart sizes.

Ball Jar Ball Heritage Collection Pint Jars in Purple, Set of 6:  Because I personally consider purple to be the new black, this is my favorite!

FoodSaver Wide-Mouth Jar Sealer: Have a FoodSaver? If so, check out this jar sealer which can be used to vacuum seal your Mason jars. This is a great option for short to mid term storage of items such as beans, rice, sugar, and salt. Store your jars in a cool, dark place and you are set with the added advantage of removing a small amount for current use without having to disrupt your large Mylar bag or bucket of food.  There is also a version for regular sized jars.  See Fast Track Tip #4: How to Use a FoodSaver for Vacuum Canning.

FoodSaver Vacuum Sealer: As long as the unit has an accessory port (and this one does), an inexpensive FoodSaver will work just as well as the fancier models. That is my two cents, at least.

  1. I am researching canning procedures and techniques as I am going to give it a shot this next season. I really had no idea that there were differences in canning jars and what the uses for each were. So much to learn. Thanks for sharing!

  2. Well, darn. With a title like “EVERYTHING you need to know and MORE”, I was hoping to get reminded about how to properly and safely use the glass lid/ rubber ring/ zinc screw-top jars from the 30s-50s. I used to use those twenty years ago, gave nearly all my canning jars away five years ago when we became empty-nesters, need to do a LOT of canning this year now we’re suddenly a family of seven — and a kind friend gave me a lot of the old “Crown” jars. They actually have dates molded into the glass, which is very cool… too bad they didn’t add instructions! People still use them, you can even buy new rubber gaskets at the store, but information about how to use them is just scarce.

    By the way, my favourite canning jars (aside from brand new Ball jars which are awesome) are the ones that come filled with pasta sauce at the supermarket. The 1.5 pint size is so convenient! You can recognize the reusable-for-canning jars because they say MASON on the side – possibly under the product label! Throw out the lid that comes with (or save it for freezer storage) and fit it with a new two-piece lid for canning. Since I never buy prepared pasta sauce, I have to scrounge from friends who do.

  3. I use my Food Saver for “canning” my dehydrated vegetables. So far so good. My question is has anyone used the solar oven to dehydrate vegetables?

    • I have not done so myself but at the Sun Oven webinar, I learned that you can definitely do so. Learning to dehydrate veggies is still ob my bucket list.
