A medium fat. It is slower drying than Art Spectrum Medium No. 1, as it contains more oil, and used as the next fattest medium in the sequence of painting fat over lean.

It should be mixed with the oil paint as the layers of painting develop in the fat over lean sequence.

The ???lean to fat??? rule

When one layer of oil paint contains an equal amount of oil as the next layer, the top layer will dry while the bottom layer will be deprived of oxygen and remain wet. This will cause wrinkling and eventually cracking. To prevent this problem, use Artists??? Oil Painting Medium No. 1 first and then Artists??? Oil Painting Medium No. 2 for subsequent layers. This will give an even tension throughout the painting. This method is known as ???lean to fat???.

Painting Medium No. 3 is viscous and ???fatter??? for those who like a heavier medium. It should be used over the leaner mediums.

(NB: ???Lean??? and ???fat??? should not be confused with ???thick??? and ???thin???. A lean paint can be very stiff and go on thickly while a fat paint may have so much oil in it that it goes on thinly.)
