I got an email from someone suggesting this, so I did it.
I was experimenting with a new formulation that doesn’t have beeswax in it (softer) but it doesn’t demold cleanly. My original “FIGHT CLUB” formula has a tendency to go solid quickly, which means you have to keep the oils warm while you’re mixing it, which accellerates the reaction, and sometimes makes the soap foam from the heat.
This is a “failure” because of the demold issues. Anyone want some otherwise perfectly good soap bars? I now have about a dozen.. Mostly FIGHT CLUB and a few BOOK CLUB.
My friend Scott at SPDtool retired from working as an IT security specialist for a university, bought a CNC machine, and makes parts for gunsmiths and soap makers. Well, mostly gunsmiths. It turns out that a chunk of HDPE machines great in a CNC and makes a perfect soap mold. Once Scott and I nail down the design, I make a few silicone molds around the master HDPE form, and start pouring soap.
