Hi, I am new to soapmaking. I have been following instructions from Norma Coney's "The Complete Soapmaker". My CP is made with olive oil and lye, and is consistent, but when I melt it down to hand mill, it seems to take forever! The book says it should only take about an hour, but a small batch (12oz soap/9oz H2O) is taking up to 2 1/2hrs to liquify. I have scorched several batches trying to speed up the process. Is there a way to add ingredients and lasting fragrances during the CP step?
