    For anyone doing chemistry work, here are some things that might help you:
    First part: Copper Carbonate + Heat ---> Copper Oxide + Carbon Dioxide
    CuCO3 + Heat ---> CuO + CO2
    Second part: Copper Oxide + Carbon ---> Carbon dioxide + Copper
    CuO + C ---> CO2 + Cu

    That's CRAZY. I had no idea ancient people made copper by heating green rocks. Blew my mind.

    I have done this quite a few times in my mini casting kiln and melted down all of it into a bar that I hand hammed into a pendant!😁

    Copper utensils doesn't become black due copper oxide corrosion but here copper oxide is black?

      It instills a wrong mindset. Pinata effect.

      Please elaborate on the details and you'll see that you're projecting some internal irrational fear by deliberately not visiting the part of the equation that you don't like.

      Your name is Taboo. Ironic.
      I think you're stretching it.
      Example:
      "Please stop" reminds me of rape, don't remind me of rape, thanks.
      Another example:
      Don't talk about pinatas, my grandma hit me by accident once and now every time someone says pinata I flinch, therefore to avoid me instilling that fear into other people's subconscious by having them see my facial expression, don't ever talk about pinatas.
