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

    Reading comprehension… What even is it?

    I do see that the light has mostly obscured a small band of blue so maybe its at a really neat phase of tarnish, but that’s speculation and this photo provides no evidence that is actually the case. Either way, I really dont think the tarnish article goes far to actually explain the blue aside from describing the mechanism.

      You sandwiched your admission that the photo showed blue tarnish on silver between a claim that the photo didn’t show blue and the false claim that the OP specifically asked why blue in particular.

      The photo is proof that silver can tarnish to blue.
