I mean I can some stuff but aside from fowlers canning jars have low availability since ball stopped selling in aus, the more usaian standard with disposable middle rings and seals are not found anywhere atm. Also jars just aren’t a good solution to leftovers or portions like cake and stuff.
I’d have a better time scrounging old dessicators with ground mating surfaces etc. Or old casserole dishes. The issue is that those aren’t widely available affordabily anymore.
I’m in the US, Ball jars and their accoutrements are literally everywhere along with their parts and accoutrements. I own several dozen and I use them for lots of stuff. I am aware of a European system that uses reusable rubber seals and glass lids; I don’t like those for canning because I like the metal lid that pops down to indicate the vacuum seal, plus they’re kind of pricey in the New World.
As for casserole dishes, I’ve got them all. My late grandmother owned everything Corningware ever made, and she left them to me when she passed.
