Essence.
Murdasanj is burnt lead, but often it is not made from lead. Sometimes they try to improve it, either by boiling it in vinegar or wine and then burning it once or twice, or by burning it on hot coals and skimming off what rises to the top. It is also boiled in water with wheat and barley until the grains burst; then they remove the wheat and water and boil it again in new water until it is cleansed and settles in this water; They do this to it several times and clean it with salt, as they did at first. And sometimes they do the wrong thing.
