Hello everyone ! First time posting....but i've lurked on the board for sometime now:) I want to try my hand at cold&hot process soap!...I have two questions? Does the CROCK POT used for HOT PROCESS SOAP have to be White....someone gave me a black slow cooker, can I use that for making soap? Have any one made LIQUID CASTILE SOAP from scratch, I want to use the liquid castile in my shower gels......I see some suppliers sell it...but I want to see if I can make it on my own first.....has anyone ever made it from scratch?
