  2. Hey, OP. It depends on the contents but it looks like you’re re-using jam/jelly jars and lids from the grocery store. If you plan on keeping them in the fridge, that would be fine, but reusing lids is not a safe practice (it can lead to botulism) if you intend to keep these on your shelves. As far as I know, re-using grocery jars is not safe either. I don’t mean to rain on your parade, I only say this to caution you.

    Please learn the basics of water bath canning before attempting to do so. [Here is a helpful link with easy instructions.](https://www.ballmasonjars.com/water-bath-canning.html)

    I see two major problems right off the bat: your pot is nowhere near big enough. It needs to be tall enough to cover the jars with at least an inch of water over the top. Second, reusing commercial jars with one piece lids is not recommended. [more information here](https://www.healthycanning.com/re-using-bottles-from-store-bought-products/)

    Edit to add one more issue: it doesn’t look like you have anything underneath the jars, between the jars and the bottom of the pot. You need something underneath, such as a towel or a rack, to protect the jars from the direct heat of your stove.

    I do think the boiling water needs to cover the jars. The time depends on the contents.

    Everything about this image is giving me anxiety.

    OP, these will not become airtight. The jars and lids are not meant for canning and they’re not safe to use. Additionally, the pot is too small and there needs to be at least an inch of water over the top of the jars even if they were the right ones. You need to use tested recipes.

    Please read the stickies on this sub before you try again.

  6. That pot isn’t big enough, I don’t think. I don’t know about those jars specifically or what you’re canning, but usually they to be submerged and covered with 2 inches of water.

    Invest in the proper equipment. You won’t regret it.

  8. They won’t. These containers are meant for one time use and are sealed with multimillion dollar machines. They are not made to be used at home. If you keep them in the fridge they’re fine but these will never seal properly. They are not shelf stable and you are playing Russian roulette with people’s lives.

    Yikes, this isn’t safe, whatever it is.

    What are you attempting here OP? If you share some more information we can help point you in the right direction.
