Are these jars OK for preserving?

They are pretty old. Big ones and small ones. They look ok  to me but I'm  concerned whether the plastic seals will survive sterilising

  • Should be ok if you sterilize using Milton (used for baby’s bottles etc back in the day).

    I just use jam jars, new or recycled depending on stocks.

    I think I'd be concerned about getting a good airtight seal, if it's for something that's going to be stored for any length of time. I generally use screw-on metal lids which are put on hot (hot jars and contents too, generally).  It might be an unfounded worry though - I've never had that kind of jar.

    Only one jam jar  at the moment.  Threw a couple away the other day

    Oops! 
    When I need jars I ask my parents to start saving them. My dad eats lots of jam (about a jar a week :o). And it's usually the Aldi ones with the nice wide tops that are easy to fill :).

  • My elderly parents sometimes used those coffee jars … the seal was so tight that Ma couldn’t open them and once Pa got poorly she had to get their Home Help to decant some coffee into a Tupperware container once a week.

    Just realised that I have several jars with mostly left over Asian spice mixes that I've ground  up. Probably better to make fresh anyway. If I  can't get the smell  out completely,  then it might even  be a bonus!

    I can't open that sort of jar because of arthritic hands so I wouldn't use them for jam, it would probably end up on the floor! Means I never buy coffee sold in those jars, but I do buy instant coffee.
