“From the cleaned soot. But if you want to make cleaned soot, then take as much of the small brown soot lumps as you want and put them in lye and let them boil down by a third and then leave the pot covered, then the impurities will all fall to the bottom and the water above has a beautiful fine hair color, which you can also brush on. And when you want to use the water, pour as much as you need out of the pot and add gum so that the color becomes shiny. And paint whatever you want and use it to shade garments or stone mountains, because it is good for painting many things and for various shading.” Haller. 1478.
