IKEA 'Korken' jars for canning

[match]

Hi,

I'm currently looking to purchase a number of clip-top 'kilner' style jars for canning things this year (hoping for a glut of tomatoes from our new polytunnel!)

I've been looking at the Ikea 'korken' jars, which are much cheaper than the brnaded varieties available:

https://www.ikea.com/gb/en/products/...-art-70213545/

However it's not clear whether or not these are suitable for 'proper' canning - i.e in a water bath or pressure canner, rather than just for sealing hot, as for jams.

The site says:

The jar has an aroma-tight seal, which makes it perfect for preserving your favourite homemade jams and jellies.
The aroma-tight seal helps food retain its flavour and aroma longer.

The jar is aroma-tight and suitable for preserving food. But bear in mind that the rubber gasket needs to be clean and in good condition to function properly.

Which doesn't really properly answer the question.

So - has anyone here used these jars for water-bath or pressure canning?

"Aroma-tight" isn't very confidence-inspiring for pressure canning. Probably water bath canning at most, I'd say, which is why they focus in their blurb on storage and preserving jams and jellies rather than on canning or bottling veg.

Don't take my word on it for water bath canning either. Better to ask Ikea.

Edited to add: Another option to clip-top jars would be Weck jars for both water bath and pressure canning.

Nope...personally I wouldn't use them.
I think you will find they may be more prone to shatter in the heat or the seals may leak under pressure/vacuum.
I have tried other cheaper ones and wasted loads of my produce in the process....or been unsure of how well it's been sealed and worried about getting botulism.
I may have been unlucky but I'd rather be sure

I use LeParfait jars and you need to use new seals each time to ensure they work.

Are you wanting to make jams, or preserve veg, soups etc?

I wouldn't use them either, Le Parfait or Kilmer every time. They last for âges.

Thanks for the advice - I too have my concerns about the quality of the Ikea jars, and will be asking them directly - but thought I'd see if anyone had any actual experience with them.

I've already got a range of Kilner, Le Parfait and Luminarc jars - all of which have worked well for canning - but not that many in smaller sizes (like 0.5L) so needing to buy more.

I'm planning on water-bath canning tomatoes mostly - I make a fair number of jars of jams and jellies, and also some pickles (beetroot, cucumber/gherkin and carrot) in vinegar - both of which methods allow some leeway in terms of process due to the high sugar/acid environment - however for tomatoes the full water-bath process (45 min submerged boil, plus lemon juice/citric acid addition) is needed.

For anyone in France looking for more jars, Weck might work out much cheaper than Le Parfait or Kilner. Certainly the case in Spain. Weck are expensive on Amazon.fr but cheap from other outlets (I've had a look at MCM Emballages, for example, but lots of others). Like Kilner jars, you only have to replace the rubber seal each usage. And they come with glass, not metal lids, so perfect for pickles too.

So I asked IKEA support if they were suitable for water bath canning and the reply was:

The only advise I can give in which is stated in the care instructions is "If you want to sterilize the jar with hot water, preheat the jar first with warm tap water. This prevents the glass from cracking.

While this isn't an affirmative answer, I'm going to assume that if they don't know, then the answer is no!

For info, after some more digging around I found that the following brands do advertise their products as suitable for canning:

• Kilner
• Le Parfait
• Luminarc
• Weck
• Bormioli (Rocco Fido)

Happy to add any others to the list if I've missed any!

I've got quite a few of these as I use them for dried herbs... Never thought to do proper canning, but I might give a couple of these a go in the summer

Mason jars made by Ball, available from places like Amazon and Lakeland, are also suitable for canning.

You can save ordinary jam jars, I usually save the jars from xmas mincemeat - can buy new pop-up lids for water-bathing passata, if you want to.
The pop-up shows that there is a good vacuum seal. A few of us mentioned it here https://www.growfruitandveg.co.uk/gr...ml#post1357326
My Passata method is here https://www.growfruitandveg.co.uk/gr...ml#post1480404

I've used the Ikea ones, or rather Husband made pickled eggs in them, but the seal wasn't good. Definitely not for canning.
