Silver containers for preserving food/juices/milk

[Steppe King]

Silver was historically used by rich nobles to preserve food.It has antimicrobial properties.

It's even used to treat burn wounds as silver sulfadiazone today.

I'm pretty sure brass is at least as good for this, right?  Copper has very strong antimicrobial properties.

doesn't copper have leeching issues or something?

Copper will outright dissolve in hot acidic foods, it can be dissolved in vinegar to make copper acetate, a pigment and fungicide. However, copper pots and kettles have been quite widely used in cooking. Copper is easily worked and has very high heat capacity and conductivity, so it's easy to avoid hot spots and get even heating, and the toxicity is low enough it's usually not a problem. It can also easily be coated with tin to prevent corrosion and allow use with more acidic foods.
