As a preliminary trial in soap making, try the cold process. Cocoanut oil should be used to the extent of from 25 to 50 per cent, if possible, as it not only rapidly saponifies but appears also to hasten the saponification of other oils mixed with it, and forms an easy lathering soap. For trial, dissolve in 1 1/2 pt. of water 1/2 lb. of caustic soda (that in hermetically sealed tins for preference); place the lye in a jug. Now raise the temperature of the oils to HOT., pour into a large bowl, and add the lye very slowly, stirring well with a stick. When the lye has been thoroughly mixed with the oils the mixture may be poured into a mould. An efficient temporary mould may be made by lining the inside of an old box with a piece of old cotton cloth, wetted, and folded in several thicknesses. Pour the mixture into the cloth, cover the box over, and place it in a warm place for from twelve to twenty-four hours. If the mixing has been properly performed, a block of hard soap will be produced, which may be cut into bars with a wire.
