Experimental set-up. A salt crust is suspended in a Hele-Shaw cell (20 mm wide, 100 mm high, with an aperture of 2 mm) with liquid water at some distance below the crust. The cell is open at the top to a relatively dry air, which induces evaporation. The Hele-Shaw cell is connected through its polymeric base to a cylinder containing liquid water.
