Dissolve two and a quarter pounds of white potash in five quarts of water, then mix it with ten pounds of myrtle wax, or bayberry tallow. Boil the whole over a slow fire till it turns to soap, then add a teacup of cold water; let it boil ten minutes longer; at the end of that time turn it into tin molds or pans, and let them remain a week or ten days to dry; then turn them out of the molds. If you wish to have the soap scented,25 stir into it an essential oil that has an agreeable smell, just before you turn it into the molds. This kind of soap is excellent for shaving, and for chapped hands: it is also good for eruptions on the face. It will be fit for use in the course of three or four weeks after it is made, but it is better for being kept ten or twelve months.
