Light microscopy images of NaCl crystals formed after drying a droplet of a solution containing 375 mM NaCl and 5 mM Tris–HCl buffer. (A) Overview image of the sample (×20 magnification), (B) selected NaCl crystal (×80 magnification), (C) detail of a top-sided edge of the selected crystal (×200 magnification) and (D) detail of deposits found away from the tabular crystals on the substrate surface (×500 magnification)
