I have my late grandpa’s silver spoon attached to my fridge with a neodymium magnet. What kind of chemical reaction causes that discolouration?

    The 800 means it’s 80% silver. The other 20% are mostly copper.
    The other symbols are maker’s marks.
    800 silver discolors faster than 925, but it’s harder, cheaper and better for daily use.
