Hot process soapmaking gives you a rare opportunity to watch every stage of soap batter develop in real time. From emulsion to light trace, medium trace, thick trace, and finally the gel phase, hot process clearly shows what is happening inside your soap as saponification progresses.
In this video, I walk through a full hot process soap batch and point out each stage as it happens. Even if you primarily make cold process soap, seeing these stages in hot process can make it much easier to recognize trace and understand what is happening in your batter.
What You’ll Learn:
- The difference between emulsion and trace in soap batter
- What light, medium, and thick trace look like in real soapmaking
- How hot process soap moves through the gel phase
- Why hot process soap often reaches a mashed-potato stage
