Water content has a big impact on how cold process soap behaves. It affects trace speed, gel phase, unmolding time, soda ash formation, and even the final appearance of your bars.
In this video, I make a set of small test soaps using different amounts of water in the same base recipe. As the bars cure and are unmolded, you can clearly see how water content influences things like soda ash and partial gel. Experiments like this are one of the best ways to understand how formulation choices affect the final soap.
What You’ll Learn:
- How water content affects trace speed and soap batter behavior
- Why different water amounts can change gel phase patterns
- How water content can contribute to soda ash formation
- What happens when soap is unmolded early with higher water levels
- Why testing small batches can help you better understand your recipes

This experiment is part of my Myth Busting Water and Temperature in Handmade Soap class, where we test common assumptions and see what actually happens in real batches of soap.
