Ever wondered what the difference is between CPOP, HPOP, and CPHP? Anne-Marie (aka Soap Queen) hopes to set the record straight when it comes to various methods of using heat to aid in the soapmaking process in an blog entry called Hot Process Series: CPOP Swirls . She will selt out to tell you of my own accounts of what happens when I attempt these different methods. She also provides a recipe for you to try. It is an advanced project that should take you 1.5 hours to make 8 bars of soap. Give it a try!
