240. Dyeing bones, horns, and woods green

First scrape whichever of these you want and put them into Asian alum: treat bones with alum for 12 days; horn, however, for 9 days; and wood for 4 days. Then cook well some weld, and while it is simmering, put whichever of these materials you want into it: and when it has cooled, mix some lulax, and put them into it, and leave for 5 days. Afterwards take them out and wash them.
