As in the grinding of colours I gave you an instance but in one for all the rest, like I shall do for those colours which are to be washed; I will make my instance in red-lead, which you are to wash in this manner.,Put a quantity thereof into a clean earthen dish, and pour thereto fair water, stirring the colour and water together with your hand or ortherwise, then let it stand a while, and you shall see a filthy greasie scum arise and lie above the water, with other filth; pour this water quite away, and put other clean water to the colour, and stir it about again, pouring away the water (if foul) the second or third time;then add more water, and stir the colour about again till the water be thick and troubled; but yet free from filth, then gently pour this troubled water into a second earthen dish, leaving in the first dish all the dregs.,Into the second bason put more fair water, and with your hand stir about the colour as before; do thus two or three times, and take (if your colour be very foul) a third earthen dish, and add more water, and keep stirring, till at last the water become clear, and the colour remain fine at the bottom of the dish; pour away your water gently, and you will find some colour remaining and flicking to the edges of the dish, which when it is dry, you may (with a feather) strike away like flower, which reserve as the choicest and purest of all; if in a pound of this red-lead you have an ounce of good indeed, prize it, for it is troublesome to procure. The other, which is not altogether so pure, may be serviceable for some uses, though not for all. What hath been said of this colour is to be understood of all other that are to be washed; therefore for washing of colours let this suffice.,
