So it has to sit for a while to mellow out, before it can be used? I have a book on Soapmaking, but it’s in a box in our cargo trailer in MS.
It all depends on which approach you use. I used a low-temperature approach which means the reaction isn’t finished until long after I pour it into the mold. There are other techniques which use higher temps to get the rxn to run faster and finish in a shorter period of time. Each technique produces different textures and looks to the soap.
