Cold-process soapmaking is the basic form of handmade, from-scratch soap-making. It is called “cold” process because there is no cooking involved. Beyond heating the oils enough to liquefy them, there is no heat applied during the creation of the soap. You will make luscious, gorgeous, gentle, bubbly soap with a fine texture with this process. The cold-process soapmaking technique is relatively simple and gets easier with practice. A blend of oils is mixed with a simple solution of lye and water, stirred until thickened, then poured into a mold.
