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

    Thanks!

    Based on the phase interaction part of the article, there’s constructive and reconstructive phase interaction going on. That chapter has some nice diagrams about it.

    That’s what produces the different colors. The thickness of the layer determines which wavelengths are lucky enough to reflect this way.

    Also, here’s what happens with iron oxide.
