The Soapmaker's Companion: A Comprehensive Guide with Recipes, Techniques & Know-How (Paperback)
Early printings of this book contain a recipe variation in a sidebar note on page 36. As a result of further testing, author Susan Miller Cavitch and Storey Publishing strongly recommend that you do not try this variation. Adding honey when you are combining the sodium hydroxide and water may result in a stronger reaction with more intense heat. The mixture may bubble up quickly and come out of the pot, posing a potential hazard.
"The Soapmaker's Companion will teach you everything you need to know about making liquid soap; laundry soap; marbled soap; transparent soap; multicolored, layered soap; and more."
“…a must-have book for anyone interested in soapmaking.”
