Hard Soap

Ingredients

Directions

  1. Take six pounds of clean grease, six pounds of sal soda, three pounds of stone lime ; slake the lime and put it into four gallons of soft water ; add the sal soda and when dissolved let it settle. Pour off the water into an iron kettle and add the grease melted, and boil. If the soap does not come after boiling a few minutes, add more soft water till it is of the consistency of honey. Wet a tub and pour the hot soap into it. When cold cut it into pieces and lay it away to dry. Always make soap in an iron kettle.

  2. Or : Put into a tub without paint, three pounds of unslacked lime and seven pounds of washing soda; pour on these four gallons of boiling rain water ; stir well and let stand over night ; in the morning dip of? the water as closely as possible, without taking up the sediment ; put it in a brass kettle and add seven pounds of clean rendered grease ; let this boil until thick, so that it will not drop from a stick, but string oflf in fine threads ; now add, if you wish, one ounce of oil of cinnamon or sassafras, or any desirable oil for perfume ; turn it out into deep earthen dishes, wet with cold water to prevent sticking ; next morning turn out of dish and let stand four weeks to dry ; lay it on several thicknesses of newspapers or cloth in a dry place and turn occasionally ; then cut it into desired pieces. Upon the remains in the tub pour a pailful of water ; stir up well and let settle again ; when clear, dip off closely as before and put in bottles or jugs for washing fluid.
