Clean the wool with fullers plant, and hold at your disposal some lamellose alum. Then grinding the interior part of gall-nut, throw it in a pot with the alum, then put in the wool and let it remain several hours. Take it out and let it dry. Follow this procedure first: Having ground the lees (from wine) and having placed them in a vessel, pour in sea water, agitate and set aside. Then, decant the clear water into another vessel and hold it at your disposal. Taking the alkanet and placing it in a vessel, mix with the water from the lees until it thickens conveniently and becomes as though sandy. Then place the product in a vessel, diluting it by estimation with the preceding water which comes from the alkanet. Then, when it has become as though slimy, place it in a small kettle, add it to the remainder of the alkanet water, and leave until lukewarm. Then plunge the wool in it, lay aside several hours, and you will find the purple fast.
