I completely missed that in the middle of the night, sorry. Cure takes place after it is unmolded.
Trace is the beginning of saponification.
Saponification takes 24-48 hours, and does not determine if the soap is ready to unmold or not.
You figure out if you can unmold by pressing gently on a corner to see if it dents. If it doesn't dent to LIGHT pressure, you can unmold and cut(or just unmold in the case of individual molds).
Cure starts after unmolding.
All soap that is not MP requires 4-6 weeks minimum cure.
