Why do salt flakes start building up in a bottle of mineral water after it was first opened? I noticed that mineral water with high mineralization doesn't have salt flakes floating on the bottom of the bottle on store shelves, but when I open one, after some time they start accumulating. Does it have something to do with decarbonation?

Salt solubility decreases with decreasing pressure.
