MAKING FOLIUM FROM ROASTED ASHES. “…when they have been white hot for a very long time, and after they have cooled, put some of them in an earthenware pot, pour in some urine and stir with a piece of wood. When the preparation has settled and become clear, pour on sone red folium, lightly grind it on a stone and add to it a fourth part of quicklime.” (Etc).
