Copper aging for tools and armor

I suggest that copper tools and armor’s effectiveness is gauged by its oxidized state. For instance copper armor could have a defense slightly lower than iron in its unoxidized state but as it ages it gives less protection and it loses durability faster. Taking damage could also speed up the oxidization process. For tools it would just be speed so at base state could be slightly worse than gold’s speed but as it deteriorates the speed decreased to say a wooden tool and it loses more durability the more oxidized it is. Additionally you could implement the option of reversing it like with the copper blocks with a tool by putting the axe and copper equipment in a crafting table but you would have to have some kind of coat in durability to both the axe and copper equipment. Lastly if you use honey to conserve the state of the equipment it’s overall effectiveness will go down slightly as a price for stopping the oxidization and if the item losses sustains too much durability loss then the honey coating would break.
