BLACK HAIR MARBLE.

To produce this variety of marble there is a screen or sieve necessary as well as a wide brush having stiff bristles. By adding gall from time to time, the black is made so expansive that a single drop will be spread out to a spot of about 8 inches in diameter. Dip the brush into sprinkling water, shake the brush well so that the superfluous water is thrown out, hold the sieve above the size and move the brush quickly and lightly over it. In this way the hair marble is finished and may be taken off.
