Why does white stuff appear as ice cubes melt? Where does it come from?
Ice cubes freeze from the outside first, so the center of the cube is the last to freeze. Ice is pure water, so as the ice cube freezes the dissolved minerals are all pushed to the center of the cube. Near the end of the freezing cycle, there isn’t enough water left in the center of the cube and the minerals become concentrated there. This is the white stuff you see. The technical name is precipitate. These hardness minerals are non-toxic. Most store-bought ice cubes are cored to remove the precipitate.
