Are there metals that should not be used for fermention

I was wandering if it is ok to use stainless steel, aluminium, enameled pots for fermentation? Similarly are there plastics and other materials that should not be used or that can be used. I'm a complete novice, the only experience was making pickles about 25 years ago and had mixed (generally good) results.

Stainless steel is minimally reactive, but still reactive. Aluminum is definitely reactive. I wouldn't advise any metal if it has long-term contact with the ferment (a stirring spoon is excepted). Same thing with plastic. The acids break it down and it gets in the food.

Your best materials are lead-free ceramic or glass.
