Pastels are is extremely permanent, a time-tested medium in use for four hundred years. If applied over a durable, acid-free surface, a pastel painting will remain fresh and virtually unchanged for several hundred years. Because there is virtually nothing in the sticks but pure pigment, nothing to degrade or fade color as oil and water do, and because the dry pigment is so densely packed, the paintings will remain unchanged for many generations.
