The ground for this rare and beautiful marble is composed of vermilion and white lead. A tint of Indian red and lake is then sprinkled over the ground by striking the handle of the brush containing the color against a stick, and turning the wrist whilst striking; some of the dots will thus become elliptical instead of circular. The sprinkling of the brush must be spread in every direction, and the spots will, as already explained, be larger as the brush is struck nearer to the work and smaller as the distance is increased. The darker spots are a strong tint of lake, sprinkled on the previously made spots by striking the brush very smartly once or twice over that part of the work where they are required. The whole must then be left to dry; after this, a light blue tint must be sprinkled very lightly over different parts of the surface, but in no part so thickly as to overpower the red. The larger spots are to be done with white applied with a sable pencil near the darkest sprinkling. Dark spots of a tint formed with blue and lake are now to be added, and the work is to be completed by white veins drawn with a fine camel's hair pencil.
