What happens during cleaning silverware? But I also found the following "recipe" in a Swedish newspaper. Put some baking powder on the foil. Put in the silverware. Add more baking powder. Pour over hot water and wait. I assume this recipe is more or less equivalent to the one given earlier since the baking powder essentially turns the water into carbonated water?
The newspaper also links to a small piece written at a University in Sweden with regards to this question. So my question is: Is any one of these reaction more "true" occurring more often naturally than the others or is it the case that a little bit of everything is happening?
Is any one of these reaction more "true" occurring more often naturally than the others or is it the case that a little bit of everything is happening? I think the best answer is "a little bit of everything". Silver sulfide forms faster but requires exposure of the silver to sulfur-containing materials like human skin, food, etc.
Silver that isn't exposed to sulfur would still be oxidized by the air, but at slower rates. So depending on the life history of the silver object in question, different amounts of the sulfide and oxide could be present. Sign up to join this community.
