Well, keep in mind that the term "emulsion" is used incorrectly and it is a misnomer.
The definitions of emulsion and suspension are:
• Emulsion - A mixture of two or more liquids that are not soluble in one another. One is suspended as small droplets in the other.
• Suspension - A suspension is a colloidal dispersion (mixture) in which a finely-divided solid is combined with another liquids, with the former being so finely divided and mixed that it doesn't rapidly settle out.
Despite the name, photographic emulsions are actually a suspension of finely divided solid silver halide crystals in a mixture of gelatin and water. But since the term "emulsion" is so entrenched in photographic history, tradition, and literature, there is no need to try and change the usage.
