|Salt & Pepper Soap, January 2020
Titanium dioxide is what I used in the white part to make it more white. I know that when I make this particular soap, I get glycerin rivers and I love the look in this case.
The Charcoal & Lavender Castile was, shall we say, educational. With the first cut, I realized it had gone through partial gel. The gel phase of soap making is the heating stage of saponification. Once you pour your soap into its mold it will start to heat up. Gel phase starts with the soap turning translucent in the middle and then spreads out to the edges. ... The biggest difference between gelled and un-gelled soap is the color of it. (From Lovinsoap.com)
You can recognize partial gel instantly. There will be a ring spreading from the center but not to the outer edges of the soap. That's what happened with this one; there was a pale grey ring in the bars. I didn't take a picture of it because I was, if I'm honest, a little disappointed. John, however, thought it was pretty cool and was disappointed when I planed each of the bars, which helped to diminish the very obvious ring.
Partial gel in no way affects the quality of the soap; like glycerin rivers, it's purely cosmetic. Both of these soaps will be amazing once they've cured, in about 4-6 weeks. Next time, however, I may force gel in the charcoal soap, for cosmetic reasons only.
