Long time lurker finally decided to make my first batches.

...how long due you typically let bastille bars sit before cutting?
I liked
@Ford 's reponse in post #2.
Ditto. With bastille, it really depends on the recipe. For example, back in the day, when I made CP 100% olive oil castile soaps, I let the batch sit in the mold for a week before unmolding. I'd wait to cut until my finger no longer put a dent in the soap.

With bastille bars, it depends on how much olive is in the recipe and what other oils you used. TIP: It's best to post your recipe with the question.
For
ZNSC, whether 100% olive oil or 85% olive, 10% coconut oil, 5% castor, the bars are usually ready to unmold and cut the next day. Here's a link:
