Gold ink

is made by grinding upon a porphyry slab, with a muller, gold leaves along with white honey, till they be reduced to the finest po ible division. The paste is then collected upon the edge of a knife or spatula, put into a large gla , and diffused through water. The gold by gravity soon falls to the bottom, while the honey di olves in the water, which must be decanted off. The sediment is to be repeatedly washed till entirely freed from the honey. The powder, when dried, is very brilliant, and when to be used as an ink, may be mixed up with a little gum water. After the writing becomes dry, it should be burnished with a wolf’s tooth.
