Black soap, or soft soap, gets its name from the dark color of the wood ash lye used to make it (and the cast iron it was often boiled in). Hard soap from southern Europe was made with high quality barilla ashes, which makes a light colored lye (and hard soda soap); therefore white soapquickly equated with high quality hard soap. Black soap was, as shown by many price agreements where it was sold in small pots, or bulk in vats, a soft soap. This pamphlet explores the sixteenth century manuscript The Secretes of Master Alexis of Piemont as a period source for soap making, and the practical concerns of recreating historical soaps today.
