This is usually made with the white of Troye, which is otherwise call'd Spanish white or French and Avignon berries; but it is apt to change colour; so that it will be better to make it of white-lead or cerussi, ground very fine on a marble. When it is ground, take it up with a wooden spatula, and set it to dry in the shady part of a room; then bruise French berries in a marble mortar with a wooden pestle, and boil them in a lidded earthen pot, till the third part or more be evaporated.

Strain this decoction through a linnen cloth, and put into it the quantity of two or three small nuts of alum, to hinder it from changing colour; when it is dissolv'd, dilute the white with this decoction, to the consistence of a pretty thick pap, or rather paste, which you are to work well between your hands, and make up into trochisks, and lay them to dry in an airy room: when they are dry, dilute them again two or three times with the same decoction, according as you would have your pink bright or deep, and set it to dry each time.

Take notice that the liquor or decoction must be warm, when the paste is diluted with it, and that you must make it a-fresh, when the first is tainted; taking care never to touch it with iron or steel; but always using a wooden spatula.
