LESSON XXX.
DESCRIPTION OF THE VARIOUS MARBLES—CONTINUED.
ITALIAN PINK MARBLE AND SCARLET MARBLE.
155. Really this marble and the Italian scarlet marble are only variations of sienna marble, and as the variation consists altogether in the coloring of the marble and not at all in its veining and other forms, there will be no need of telling “how” it should be done, as that is related under the heading of sienna marble in the following paragraph. For color venetian red lightened up to a pink with white lead is used instead of that described, and in the scarlet variety vermillion toned down with venetian red.
SIENNA MARBLE.
156. This marble is more extensively imitated than any of the others, with the exception of white marble black veined, and there is no wonder that it is so with its wealth of forms. No matter what one may fancy or do it is pretty sure to look like some specimen of it has done before if the same character is kept up to the end. It is true some forms are more pleasant than are others, and that is true really in all marbles, so that the student should not spend much time in trying to do something which is considered an inferiority in the sienna marble itself. The most pleasing forms are clumps of darker color overrun with veinings and intervals of lighter tone also veined, but usually with much lighter toned veins than the set occupying the darker clumps. But some of the light as well as the darker ones usually trespass some upon each other’s ground, and in some specimens clumps of very fine dots extend over some of the light areas instead of veins.
