Egg yolk by itself dries up and cracks, but in the middle ages it was very popular to create a yellow color for a paint. To create this paint (called Tempera) the egg yolk would be added to oil on a 1:1 basis. The two substances become a solution, and the oil keeps the egg yolk in a consistency we think of with paint (thick and viscuous).
Some sort of acidic substance is also added usually, like vinegar or white wine.
When the tempera is used for painting, it dries quickly, and the oil causes the pigment in the egg to bond with the surface that is painted.
See the related link for examples of Tempera art.

Emulsifiers are substances that can mix other substances together that won't normally mix, for example you would use egg yolk to mix oil and water together. They do this by having a hydrophobic end that is attracted to the oil molecules and a hydrophilic end that is attracted to the water molecules, consequently bring the two substances together. They can be found in common foods like mayo and jam.

Egg oil emulsion is however made with tempera paints ( a dry ground pigment) not with water paint. For additional information on, and how to mix egg oil emulsion, please see the related link below.
