"WebAbstract. Solids dispersed in an evaporating drop migrates to the drop edge and form a solid ring, leaving ringlike stains on the surface. An outward flow within the drop is identified, which is driven by solvent loss by evaporation and geometrical constraint that the drop maintain an equilibrium droplet shape with a fixed boundary.
