Home-Made Hard Soap
1 lb. fat 1 pt. cold water
1 can lye 1 tbsp. borax
Melt the fat slowly. Mix the lye and water in a bowl or kettle (do not use a tin pan), stirring with a stick until the potash dissolves. Add the borax and allow the mixture to cool. Cool the fat and, when it is lukewarm, add the lye, pouring it in a thin stream and stirring constantly. Stir with a smooth stick until about as thick as honey, and continue stirring for ten minutes. Pour the mixture into a box and allow it to harden. Cut into pieces the desired size and leave in a coo], dry place for ten days, to ripen before using.
When making the soap, be careful not to spill potash or lye on the hands, as it makes a had burn. If the hands are burned, rub them with grease at once. Do not wet them.
Before this lesson is given ask the pupils to bring scraps of fat from home. See that these are in good condition, and weigh them, to determine the portion of the recipe that can be made. Ask one of the pupils to bring sufficient borax for the recipe.
METHOD OF WORK
Let the pupils look the fat over and put it on to melt, watching it carefully. While it is heating and cooling. discuss the process of soap-making, the cost of materials. the care necessary in the making of soap, and the importance of its use. Get ready the other materials, and a box for moulding the soap, and Iet the pupils work together. After the soap has hardened and been cut, have it put away on a shelf to dry.
