I have my late grandpa’s silver spoon attached to my fridge with a neodymium magnet. What kind of chemical reaction causes that discolouration?
I have my late grandpa’s silver spoon attached to my fridge with a neodymium magnet. What kind of chemical reaction causes that discolouration?
Why did it spread from the magnet?
Not sure what exactly that means.
There’s another magnet below to hold the other metal sign. The stainless steel fridge looks fine.
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.
