Wrap the tub or barrel well up in blankets or sheepskins, and put away for a week in some warm dry place, during which the mixture slowly turns into soap, giving a produce of about 120 pounds of excellent potash soap. If this soap is made with tallow or grease it will be nearly as hard as soda soap. When made by farmers or householders tallow or grease will generally be taken, as it is the cheapest, and ready to hand on the spot. For manufacturers, or for making laundry soap, nothing could be better than cotton seed oil. A magnificent soap can be made with this article, lathering very freely. When made with oil it is better to remelt in a kettle the potash soap, made according to the above directions, with half its weight of water, using very little heat, stirring constantly, and removing the fire as soon as the water is mixed with and taken up by the soap. A beautifully bright soap is obtained in this way, and curiously the soap is actually made much harder and stiffer by this addition of water than when it is in a more concentrated state previously to the water being added.
