CHAP. V. How to grind Colours with Oyl.

WHen you come to grind Co∣lours, let your grinding-stone be placed about the heighth of your middle; let it stand firm and fast so that it soggle not up and down; then take a small quan∣tity of the Colour you intend to grind (two spoonfuls is enough) for the less you grind at a time, the easier and finer will your colour be ground: lay this two spoonfuls of Colour on the middest of your stone, and put a little of your Linseed Oyl to it, (but be sure you put not too much at first)

then with your Mulier mix it toge∣ther a little, and turn your Mulier three or four times about, and if you find there be not Oyl enough, put a little more to it, till it come to the consistence of an Oyntment; for then it grinds much better and sooner then when it's so thin as to run about the stone: You must of∣tentimes in the grinding bring your Colour together with your piece of Lanthorn horn, and with the same keep it together in the middle of your stone; when you find you have ground it fine enough (by the continual motion of your Mu∣lier about the stone, holding it down as hard as your strength will permit, which you must also move with such a sleight, as to gather the Colour under it) and that no knots nor grittiness remains; then with your Horn cleanse it off the stone into a Gally-Pot, Pan, or what ever

else you design to put it into: and then lay more colour on your stone, and proceed to grinding as before: do so thus often till you have ground as much of this same Colour as shall serve your occasions; and if you grind other Colours after it, let the stone be well cleansed from the first colour with a cloath and fine dry Ashes.
