White.
Put white-lead in a pan, a cord's thickness throughout, and leave it fifteen days in the sun and the open air; and see that in the morning, when the sun has dried the night's dew, you sprinkle it hour by hour with a little bristle-brush; and each day put on enough water to make it liquid like a sauce, so that by stirring... the water... received...

If you wish to revive oil colours that have dried, keep them soaking overnight in the master-lye of soap, and with your finger work them with that lye, and pour into a glass and wash it with water; and in this way you will recover the colours that dry up. But see that every revived colour has its own glass, giving it its own colour one by one as you revive them, and keep them soaking; and when you wish to use them in tempera, wash them five or six times with well-water and let them settle. If the lye becomes turbid with any colour, pass it through felt. The said strong lye strips the crust from corals and snails and shells when they soak in it for three or four days; and warm it works better.
When you take the vessels out of the said lye, pick them up with a pair of tongs and put them in fresh water, and after a while wash them with a sponge, otherwise it would blacken your nails. Taking a great quantity of the said lye and drying it and then burning it, as is done with the tartar-crust of wine, and then making oil of it, as is done with that of tartar, it would have the power to dissolve bone. Fine yellow. Dissolve realgar, or if you wish orpiment, with aqua fortis. Calcined arum roots make a strong lye. The mouth has killed more men than the knife.
