Thanks for this! It keeps them for decades? Wow.
Most of the techs I imagine are not new, just traditional ways of doing stuff that have been lost over the years because of capitalism, and are revived using new tools. A jar like this gives me ideas, perhaps there's a whole vault full of them, or granaries/silos built like this to store very large quantities of food. For decades? Thanks a lot for the pointer!
