The pastels are sticks of pure pigment. The pigment is the same pigment used in oil paints, watercolors, and acrylics, except that it does not have oil, water, or acrylic added to it. It is the pure pigment, pressed into sticks, held together with a little binder. The pigments are very small crystals of color, with facets that reflect the light, much like diamonds do.

But was I finished? I felt another painting of this beautiful scene needed to be created. Hmmmmm.
