Fun fact about the method of soap I make – it’s called Cold Process soap. It means once I blend the oils, fats, butters, milk and sodium hydroxide, add scent and color, pour into my molds, and insulate with old blankets, there’s no external heat source applied. It sits in the molds for 24-48 hours making it’s chemical transformation to soap. Then I cut the soaps, and put them on the curing racks:
Why does soap have to cure? Well, it completes the saponification process – transforming the oils, fats and butters into the compound we call soap. While you can use soap within a week or two, it’s not quite dried out yet. And the longer you allow the soaps to cure, the harder then are (meaning they’ll last longer), the more mild they are on the skin, and I think it adds to the bubble factor (soaps I have cured for ages upon ages are super lathery!)
Hemlock Springs Soaps cure for anywhere from six to eight weeks. Or more. I am using a bar of soap I made last spring and it’s simply divine! It still smells great, lathers like crazy, and is as hard as a rock. Winning!
PS – I have had a few inquiries of late for custom bars and batches of soaps for personal use and party favors. There are all sorts of cool things we can do for you if interested! Contact me anytime for a brainstorming session.
