We observed the drying process of Pickering emulsions with a microscope. In the case of water-in-oil (w/o) emulsions stabilized by common surfactants, the emulsion droplets shrunk while maintaining their spherical shapes. On the other hand, in the case of w/o emulsions stabilized by solid particles, wrinkles occurred and expanded on the droplet surfaces. The colorant dissolved in the water phase remained in a wide area after drying.
