My mum when I was a kid in the 90s: we don't store things in plastic, glass or ceramic only Me when I was a kid in the 90s: mum is a f'ing idiot wtf is wrong with plastic this hippy shit is dumb My mum 2020s: so plastic huh? Me 2020s: ugh.
We've got sets of Indian brass, Korean steel, and Japanese lacquered wood food containers that we use in addition to ceramics and glass. The glass chips, and once it does we tend to avoid using it for food. Because all of these things last or compound over a lifetime, it's only expensive to be healthful if you wait.
I could find images for Indian Brass Container to learn what it is. But I didn't find anything conclusive for Korean steel.
