These blocksare broken up with wooden mallets, and three of them are loaded into anincorporating machine, which is run for about fifteen minutes before any etheris added in order that the lumps may be broken up to a fine powder. Then48-4 lb. of ether are added and 6 oz. of diphenylamine to act as a stabilizer,so that the charge consists altogether of : Nitro-cotton Alcohol .... Water .... Ether .... Diphenylamine The incorporator is kept covered to prevent loss of solvent, and incorporationis continued for forty-five minutes. The white, finely comminuted m
