Pigment Properties

This term refers to the significant physical and chemical properties of a pigment other than its color qualities. Paint pigments must be completely insoluble in their vehicles; colors that are soluble in water or other paint liquids are called dyes. No soluble dyes are permanent. They must be smooth, uniformly fine powders capable of remaining in suspension in the vehicles with which they are compounded, so that their color, degree of opacity, and general optical effects can be smoothly and evenly applied to the surfaces of paintings. [p. 26] [The dry powdered pigments, from which artists' paints are made, must conform to several requirements in order to be acceptable for use in painting. ]
