Oil Paint
Drying Oils
As a paint film dries, I understand that it increases in mass rapidly as it takes up oxygen, reaches a zenith and then reduces in mass at a slower rate before "leveling out" at a very minimal incline, indefinitely, when graphed on a chart. Most of this change seems to take place within a few days, depending on the rate of drying.
As the paint layer gains and loses mass, does it also thicken, expand and/or shrink?
If so, it seems to me that the farther that the film progresses through these changes before another wet paint layer is added, the less movement the next layer has to deal with, especially getting past the more sudden gain and loss of mass in the first few days. Longer and more rapid drying would seem to help in the "more flexible over less flexible" paradigm. Correct?
Thanks for your thoughts,
Richard
