The invention is a method of producing dispersions of aqueous globules in an aqueous medium. The aqueous phases are rendered insoluble or immiscible in one another by the presence in separate phases of colloidal ionic reactants, preferably macromolecular polyelectrolytes, which are opposite in charge. The dispersed globules are larger than colloidal dimensions, and may be as large as one-half inch or more in length. If desired, they can be separated from the continuous medium and dried as discrete particles. When one or more of the aqueous phases are different in color, the compositions are useful in producing multicolor coatings, ceramic glazes, and fibrous webs. The dispersion is unique in that each of the dispersed globules possesses such plasticity and coherence that it may be subjected to substantial shear without subdividing. The dispersion when the globules are colored may be applied to a desired surface to impart either a first or second decorative appearance thereto. The first decorative appearance is attained when some of the globules are colored differently from others, and the suspending medium is substantially clear or translucent. On application of the dispersion to a surface, due to the resilience and cohesiveness of the material defining the globules, the globules appear in a uniform spaced relationship and assume a configuration which is relatively independent of the method of application. The second decorative appearance is attained when both the globules and suspending medium are colored and different in color from one another. The pattern obtained by application is then variable in accordance with the method of deposition. When the dispersion is applied by brush or roller, inherent small variations in film thickness result in different flow patterns of globules and suspending medium, imparting a striated or mottled decorative appearance to the surface corresponding to the directional shear or geometrical configuration of the application tool.
