Reconstruction of the liquid phase in the top 5 mm of the (a) fine and (b) coarse sand 8 hours after the onset of evaporation with the colour map representing the solute concentration percentages. Colours closer to red indicate higher concentrations. Also presented is the dynamics of solute distribution in (c) fine and (d) coarse sand at various times from the onset of the experiments (indicated in the legend).
