Pulverize the finest colored madder and thus make the test.
Purple-colored and fast archil is as if snail-colored, but the white-spotted and black is—take notice—not good. Now if you chew genuinely colored archil into pieces then take and hold it in the hand {to examine it).
Alum should be moist and very white. That which contains saltiness is, however, unsuitable.
Concerning
flowers of copper, that is suitable which shows a dark blue color, a
very green leek color or, in general, a very fine color.
121. Dyeing Canusinian Wool.
Boil,
beforehand, in a leaden kettle 20 drachmas of krimnos, 8 or else 12
drachmas of thistle, (and) 1 chus of water for 1 mina of unmordanted
wool. Then put the wool in, make a sample and it will be Canusinian
wool.

Take
heat-dried quicklime and golden litharge, grind both substances in an
earthen vessel and stir up. Put the wool in, leave it there a day and a
night and the color will come up on it. You should rinse it off with
soap weed. When it has been rinsed and you desire (to color) it
further, then after the bath, dye it again in the aforementioned dye
liquor.
123. Dyeing in Purple.
Bright
red purple; juice of archil. If you desire a deeper shade then put in

129. Another (Recipe).
Cold-dyed
purple. Pulverize quicklime in cistern water. Pour the lye off and
mordant what you wish therein from morning until evening. Then rinse it
