Vehicle Absorption

The amount of medium required for a color can vary considerably and may range from 15 percent to 200 percent. Although painters need not measure quantities like manufacturers, but may rely on guesswork, it is a matter of some importance. Some glue media dry with great tension. The more medium the paint contains, the more readily it will crack. Oil media tend to yellow, and excess oil will cause wrinkling. Painters are therefore interested in pigments that have the lowest possible pigment-binder ratio, especially since these often have a better consistency in the tube. [p. 63]
