Love handmade soap but tired of waiting 4-6 weeks to use your cold process soap? Or, perhaps you never really got into CP soapmaking due to the long curing time? What’s a soapmaker to do? The Answer: Hot Process!

Hot Process (HP) is another method of making soap completely from scratch. It differs from the more common Cold Process (CP) method in that heat is applied to complete the saponification process before the soap goes into the mold. The result is a great bar of soap, similar to what you get with the CP method, with one HUGE BENEFIT; the soap is technically ready to use immediately (although it’s a good idea to allow a few weeks for the soap to firm up). For those of you who plan on selling your soap, a reduced curing time means that you can fill custom orders in half the time (and HP soap uses less scent so that will save money). Saving time AND money… what could be better?

This class handout focuses on the Crock Pot Method of Hot Process soapmaking. A Crock Pot is the most popular name brand for a Slow Cooker, and of course any brand can be used for HP Soap). You’ll learn everything there is to know about making HP Crock Pot soap, including what equipment & ingredients (oils, colors & scents) work best, what flash points are and why they are so important when hot processing soap. Check out a cool video on watching hot process soap on our blog!

This Class Handout assumes that you have either taken a Cold Process 101 Class or have experience making soap from scratch on your own. If you have never made soap from scratch before (cold process or hot process), you can learn from the comfort of your own home using Ruth’s CP 101 Soap Video eClass, which comes with Lori’s CP 101 Soap Class Handout.

NOTE: Hot Process is not the same thing as “Melt & Pour,” which is soap “crafting” (not soap “making”) using a pre-made soap base. If you are interested in Melt & Pour Soap Crafting, check out the amazing library of eZines & Class Handouts from Debbie of SoapyLove.
