Bone Gelatine

The bones are boiled to remove the fat, then digested in diluted muriatic acid till the earthy matter of the bone is dissolved. The gelatine, which retains the form of the bone, is washed in a stream of water, plunged in hot water, and again in cold, to remove all remains of acid, and sometimes put into a solution of carbonate of soda.

When well washed, it is dried on open baskets or nets. By steeping the raw gelatine in cold water, dissolving it in boiling water , evaporating the jelly, and cutting it into tablets , it may be dried and preserved in that form.
