Cold-process soap is made in several simple steps: prepare, mix, mold, cut, and let dry. Here is what really happens in the workshop.
1. The formula is prepared
Each oil and butter is weighed according to a precise recipe. The lye and water are calculated for this specific formula. Nothing is done "by feel": the consistency of the soap begins before mixing.
2. The ingredients are mixed
The fats meet the lye solution and gradually transform into soap. The batter thickens. This is the moment the soapmaker monitors its texture before moving on to molding.
3. The batter is placed in the mold
The batter is poured and then left to rest. The loaf hardens enough to be unmolded. "Cold" does not mean "without heat": the reaction produces it naturally, without intentional cooking of the batter.
4. The soaps are cut
The block is cut into bars. A slight difference in shape may appear from one soap to another. This reflects the artisanal process, but the weight and formula must remain precisely monitored.
5. They dry before sale
The bars rest on shelves to lose some of their water and become firmer. This time does not magically transform a formula. To understand the method, also read our guide on cold saponification.
In short
Weigh, mix, mold, cut, let dry. Five steps, a great deal of precision, and no empty promises: the process describes the manufacturing, not a guaranteed result for every skin type.
