Make Your Own Cold Process Soap

Learn how to make your own vegetable-based natural soap from scratch using the cold process, which blends oils with a lye mixture. Explore the history and basic chemistry of soapmaking, safety considerations, and essential materials. After coloring your soap with micas, herbs, spices, and clays, you’ll add scents and prepare your mold, then learn techniques for insulating, cutting, curing, and storing your finished soap. You’ll take home a customized batch of soap, the mold, and detailed handouts to continue making soap on your own.

NOTE: For safety reasons please wear or bring a long-sleeved shirt. You'll also need to bring an old towel or blanket to insulate your soap on the way home.

Jennifer Hofmann is the owner of Jennifer’s Handmade Soap based in Ayer, MA. She has been making soap since 2009 where she fell into it by accident. Once she made her first batch she found she couldn’t stop. She was fascinated by the science of soap making, but it was the design possibilities that captured her love for soap making.  Her soaps are visually appealing, but also natural, gentle, and moisturizing.  Jennifer has dedicated herself to learning her craft and has passed the Soap Guilds master test (a two year test encompassing all aspects of soap making) to receive her Masters CP/HP Soap Making certification. She is also a HSCG certified teacher.
