When I first started becoming truly enthralled with canning, I began to look beyond the standard Mason/Ball/Kerr jars available. I discovered the Weck jars that are typically used in Europe, but was put off a bit by the price tag and the fact that they are often hard to actually get (I did break down and order a half dozen from Lehman’s, but with shipping, they cost somewhere in the neighborhood of $7 a jar. That is far too much for the volume of canning I typically do).
However, when I took a close look at the way in which the Weck jars seal, I realized that they are practically identical to the vintage bailing wire canning jars that were popular in this country through most of the 20th century. The glass lids on the Weck jars seal via a rubber gasket. Through the hot water process, everything is held in place by a couple of metal clips. The glass lids on the vintage jars seal via a rubber gasket. During canning, the lid is held in place by the metal wire that locks up over the lid. The thing that makes the vintage jars even better than the Weck jars is that you have an easy way to keep the jar closed after you’ve opened it, via the bailing wire. When you use the Weck jars, you have to keep replacing the metal clips (or get a set of their plastic lids).
So once I figured out that the jars I already had (and had gotten for free when helping a friend of a friend clean out her mother’s basement) would do the exact same job as the spendy ones, I got down to work. I ordered a set of rubber gaskets from Lehman’s for just over three bucks (they’re the only ones who still seem to carry them) and made a canning plan.
I did a mixed berry jam, because I’ve been endeavoring to clean out my freezer, in preparation for the coming onslaught of produce and still had some frozen fruit from last summer. I supplemented my frozen strawberries and raspberries with some fresh (but cheap and decidedly not local) strawberries (I made up for it the following week by hand-picking 13 pounds of local strawberries and making the best jam I’ve ever tasted. That recipe is coming later this week).
When canning with these jars, most of the steps are the same as with the screw-top jars. You clean your jars, lids and seals well, prepare your jam and fill the jars. Once the jars are filled, you wipe the tops clean and the apply the rubbers (clean thoughts, kids) and top with the glass lids (of course, making sure that your vintage jars and lids are without chips, cracks or other damage).
Lock the bailing wire into place and lower the jars into the hot water bath. Process as usual (this recipe calls for a 15 minute process). When the time has elapsed, remove the jars from the water, being careful not to tip them (these jars are mostly glass, which means that if you get the jam on the top of the lid, you’ll see it, and if you’re a bit of a perfectionist, this will make you sad).
The next day, when the jars are all cool, unlock the bailing wire. The lid should not move in the slightest. Test your seal by picking the jar up by the glass lid (don’t go crazy, just lift an inch or two above the countertop). It should hold fast. If it doesn’t, your seal is no good. If it holds, lock the wire back into place (you don’t need it there to hold the lid in place anymore, but it makes for better storage) and store as you would any other sealed jar.
I do have a jar of this lovely mixed berry jam to give away, but I’m giving away pint canned in a conventional jar. I trust these old jars, but I don’t know how well they’ll hold up when shipped, so I’m not going to risk it. A warning – this jam is a bit loose (some might call it syrup-y, I wouldn’t argue with them), but is amazing stirred into plain yogurt or cottage cheese. If you want a shot at it, leave a comment. I’ll pick a winner on Friday, June 12th.
Mixed Berry Jam
8 cups mixed berries (if frozen, let defrost thoroughly) with their juice
5 1/2 cups sugar
2 lemons, zested and juiced
2 teaspoons vanilla extract
1 box liquid pectin (you’ll use both packets from that box)
Pour the fruit into a large pot (think 8 to 10 quarts, this stuff gets bubbly). If there are still big hunks of fruit, smash them with a potato masher, or puree with an immersion blender a bit. Add sugar and bring up to a gentle boil. Add the lemon juice and zest and let everything simmer. Cook for 15-20 minutes, until it starts to look very syrup-y. Bring up to a rolling boil and add the pectin. Let boil for an additional five minutes then kill the heat.
Ladle into prepared jars, clean rims, apply lids and process in a hot water bath for 15 minutes (remember that you don’t start timing until the water has reached a boil).
Eat on toast, stirred into oatmeal or in yogurt. This recipe will make between 5 and 6 pints (it depends on how much liquid was in the fruit).

I swear that you must be reading my mind. I just picked up an old Mason jar (just clear) this weekend that requires a rubber seal and wondered where you get them. But since I only have one, I’ll probably hold out on using it for canning anything quite yet. I mostly bought it because it was pretty and only $1.
Andi, those types of jars, even without the rubber seal, are good for holding things like nuts and raisins. -Marisa

Oooh, I’ll take a shot! I love the sound of a runny jam…especially in yogurt with some oats? Yes please. Once local berries are ripe, I might be hitting up your blog with canning questions!
Kickpleat, we are on the very same wavelength. This morning I ate that exact runny jam with yogurt, oats, banana and pecans. Also, please send any questions you have my way, I’d be happy to answer them! -Marisa

I was looking at the link you posted a week ago for small batch strawberry jam and thinking of making it tomorrow or the day after. Is your recipe also small-batch friendly at all?
(and, yes, I’d love a shot at the mixed berry jam)
Livia, you could divide this recipe in half very easily and it would make a nice, small batch. The only sticking point with dividing it further is the pectin, as you’re sort of stuck with the amount in each packet. However, you could also try your hand at jam-making without pectin. You’d need to extend the cooking times, but it is possible. -Marisa

I grew up in an orphanage where we made jam in these old jars! We canned in large quanties, but used small jars when we ran out of cans. Especially making pickles; which we did in the old large crocks filled with spices and brine and left sitting for days. What a reminder of my childhood! THANKS Marisa!
Pat, you’re so welcome! Sounds like you had an interesting childhood! -Marisa

I want a shot at winning this jar of yummy. Question, are the rubber rings reuseable or do you need to replace it with a fresh ring each time you reuse the jar?
e, unfortunately, you can’t reuse the rubber rings. They become a bit compressed during the canning process (which is a good thing, as it means your food will be safe to eat) but that means that they also lose the springiness which allows for a good seal. However, they cost less than $3 for a dozen, which makes them pretty darn cheap (and cheaper in comparison to the rings and lids that you get at the grocery store). -Marisa

hi marisa,
this is such a great idea! i love, love, love the look of those old jars but don’t have any because i figured i couldn’t really use them to can. now i am inspired to go out and look for some. i must admit i not versed at looking for them.can you give us some pointers on places to find them?
thanks!
Tigress, I’d start with your local thrift and antique stores. Many garage sales will yield a few. You can also often buy boxed lots of them on ebay for cheap. If you find the jars without the glass lids, you can also typically get replacements on ebay that aren’t too pricey. -Marisa

My grandmother used to have glass-top Ball jars, and she’d use them to put up all manner of foods. I used to love wandering around her enormous pantry (she lived in an old farmhouse), “shopping” for our noon-time meal (called dinner, in true rural-American style).
Rebecca, what a lovely memory to have! I also shopped in my grandmother’s pantry as a kid, but hers was lined with canned food from the grocery store and was in the garage, so it wasn’t quite so picturesque. -Marisa

The jam looks delish, but I thought it was considered unsafe to use anything but the regular mason flats/rings combo. I have thought about using my glass top jars, but everywhere I read says no. (and I have a slight fear of the canning police showing up at my door)
Tara, your question deserves a post of its own. I’ll have it up later today. -Marisa

Pam, I always give jars of jam to my down-the-hall, elderly neighbor, Charlie. His favorite thing to do with them is eat them over ice cream and he too appreciates the runny jams! -Marisa

awesome! I did some canning 2 summers ago (peaches, apple butter, and a praline syrup), and really want to get back into it this year. i made some refrigerator pickles 2 nights ago and am gonna crack them open tonight to see how it went. It’s sort of a recipe test run, as I’m also trying to grow my own pickling cucumbers in my little patio ‘victory garden’. fingers crossed!

I love your blog and the jam sounds delish. I ordered canning supplies, but alas, the canning rack I got is too big for the 2 pots I already own. Bummer. But as soon as I figure out a solution to this problem, I’ll make my gramma proud and get to canning!

Hey Marisa, I remember my Granny Bartlett canning using hot liquid parafin wax to pour over what went into the jar. Have you pondered that technique at all? I remember great fun in opening a new jar and tipping off the cooled parafin and licking the bottom of it for some straight jam flavor.

Thank you so much for this post. I, like you, got very excited with canning, and canned BBQ sauce that I made, peppers, and even tried my hand at marmalade. The vintage jars have always been very appealing to me, and I do believe I’ll be trying them out, once I acquire some.
