I like to paint with many thin glazes of color, but since painting time is always short, I dont like wasting the time it takes for one glaze to dry before I can add another. To cut down on the drying time of each layer of color, Ive started painting on top of a lightbox. This is how it works: Before I start painting, I preheat my watercolor paper by placing it on top of a hot lightbox. I then turn the light off, paint a glaze of color, then turn the lightbox on again to speed up the drying time. Then Ill paint another glaze of color and so on and so on. This gentle heating cycle shaves about one-and-a-half hours off of each painting sessionand even helps keep my watercolor paper from buckling.
