I'm getting into preserving, and while I plan to reuse supermarket jars as much as possible, I want to get a quantity of larger reusable jars for bulkier products. I would be interested to hear what jars folks here like to use and also hopefully get a better understanding of the options. 've been looking into the alternatives and there are a couple of things I don't quite understand: 1. Why is the Vacola stuff so expensive?! Used jars for $5 each without lids or seals seems insane. I'm also concerned by suggestions that the Vacola jars can be tricky to open, thereby damaging the metal lids and costing even more to 'run'. 2. Mason jars are available here at a reasonable price, and supposedly use an integrated metal lid & seal that should be replaced each time. Sounds good, except that every search I do for Mason seals simply turns up rubber rings, not integrated lids. What am I missing? 3. Coming from the UK, clip-top Kilner type jars seem the most familiar and traditional to me, but a lot of these jars available here are clearly intended for dry storage and not for serious preserving. Any idea what the difference is / what to look for? FWIW I'll be doing this over a wood stove and I'm leaning towards the clip top Kilners, but I'd be very interested to hear what others have to say.
