What causes air bubbles in drywall compound?

When joint compound dries, it has to be able to do two things: evaporate and be absorbed. The tiny bubbles, called “pocks,” are trapped air bubbles created because there is a barrier—such as paint or primer or a harder mud, plaster, etc. —that will not let it be absorbed [into the drywall].
