Warning about using a metal lid on your kimchi jar

My friend in Portland said to always use a glass weight, but I tried a metal lid for 3 days and it started to rust. Anyone know a good glass weight brand under $20?

Yeah, the rust thing is no joke. I had the same bright idea with a metal lid once and it ruined a whole batch. That salty kimchi brine just eats through anything that isn't glass or ceramic. I ended up grabbing a simple glass weight from the local Asian market for like twelve bucks. It's just a plain disc, but it works perfect.

Oof, @danielm48, that's a painful lesson.

I read a whole article about that exact problem, sammurray. They said even some food safe plastics can get cloudy and hold smells after a while with the strong acids in fermenting. Glass really is the only thing that never reacts.
