I Have in the last section told you what colours are to be grownd, which washed, and which to be steeped; it resteth now, to shew you how to grind those Colours that are to be grownd; I shall not run over every colour particularly, but shew you how to grind one colour, which take as an example for all the rest.,For our example in grinding of colours, let us take the original of colours, viz. ceruse, or white-lead, there is little difference between them, only one is refined, the other not.,To grind it do thus; Take a quantitie thereof, or of any other colour to be grownd, being cleansed from all manner of dirt or filth, which you must first scrape off; then lay the colour upon your stone, and with your muller bruise it a little, then put thereto fair spring-water, and between your muller and stone grind the colour well together with the water till the colour be very fine, which when you find to be enough, have in a readiness a great chalk-stone, in which make certain troughs or furrows, into which pour your colour thus grownd, and there let it rest till it be thorough drie, then take it out ans reserve it in papers, and those papers in boxes, for your use. This order you are to observe in all colours that are to be grownd.,
