THE GRAYISH GREEN MARBLE.
This is one of the most beautiful specimens of marble and according to the shading of the body color most beautiful effects can be produced by it. The following colors are used to produce it; black, carmine-red (1 part carmine lake and 1/2 part black), gray (1 part black and 10 parts white), finally gall-water and the body color.
The mode of producing it is the same as described before. The body color consists of 1 part black, 2 parts of sprinkling water and as much green as is necessary to produce the desired shade.
Before adding sprinkling water to the body color, black, only so much gall is added that it will but slightly push the different colors thrown on.
HAIR MARBLE.
THE HAIR MARBLE.
(SEE [SPECIMEN PLATES].)
These marbles are in great use and are much liked on account of their rapid and easy production, especially when many books are to be marbled; they appear very elegant on account of their fineness.
For hair marbles but one or two colors are employed which are diluted with water to 1/3 their volume. Add enough of gall to the first color so that in throwing the same on the size it will spread sufficiently to form a ribbon from 5 to 6 inches wide. Take a whisk and throw on the second color in drops that are not too large and as nearly as possible, equally distributed, then, with the bristle-brush, or sieve and brush throw sprinkling water on the colors. In this way hair veins are formed, showing more or less ground according to the quantity of sprinkling water thrown on.
The size is produced for all hair-marbles alike. In the morning boil 3-1/5 ounces of carrageen moss in 7 quarts of water and after the boiling add 1 quart of cold water, stir the whole mixture several times and allow it to stand during the day until it is fully cooled off. In the evening the size must be again diluted by another quart of water and it is then filtered through a piece of linen and left to stand over night. The next day it is ready for use. This holds good during the summer months as the temperature of the air will just make the size useful for this purpose. During the winter months the size must be allowed to stand for 36 hours before use.
