One of them (fig. 31, upper left) has two cavities side by side, each stained with a different color of pigment. These mortars are not large, they range in length from to cm., in width from to cm., and in thickness from to cm. Their cups range in diameter from to cm., and in depth from to cm.—only large enough to contain a small quantity of material, such as pigment.
