This is a medium from the Dark Ages and few of today’s painters have had the opportunity to work with it. Sauce was a nearly-extinct medium that offered a full ten-value tonal range, but in the tumult of the last century, Sauce was all but lost to the world’s artists — it survived only in Russia. It is a stick much like a soft pastel, but when applied to paper, it gives a sensation of warm silk: slightly greasy but not oily. Breaking the Sauce down into its powder form can add to the versatility of its use. Each wooden boxed set contains 10 sticks which measure 7/16" × 2½".
