Why We Cure Our Soap for Six Weeks

Cold-process soap finishes saponifying within a few days, but curing is a different process entirely — it's about water evaporating out of the bar.

A bar cured for six weeks is harder, milder and lasts far longer in the shower than one sold at two weeks. We weigh bars weekly until they hit our target.

It's the least exciting part of soap making and also the one we'd never skip.
