(forge1.20.1)

This mod adds a new use of copper, namely crafting copper weapons, armor , tools that have an oxidation system. Copper objects gradually oxidize during use, changing their texture and characteristics.
When maximum oxidation is reached, copper objects, when instead of further oxidation, impose on themselves a new enchantment
"oxidized" which gives an improvement when a certain level of this enchantment is reached.

• 
  The oxidation of copper objects can also be rolled back using the new stand "Oxidizing stand" after which you can get an "Oxidized Residue"
  (when oxidizing items with the "oxidized" enchantment, you will get more "Oxidized Residue") and then using it to get "Oxidizing Potion"
  , "Oxidizing Potion" is used to quickly oxidize copper blocks or to blacken gold blocks.
  Black gold blocks can be converted into black gold, with the help of black gold you can bargain with a brutal piglin and get useful and new resources.
