@Belassi That is very interesting to know. Would you care to give more details on that please?

@Belassi thank you for the advice. I do believe there is precipitation of the soluble carbon carboxylate only in hard water, if the soap is made and diluted with a rather soft water. Isn’t that correct? I made some small batches in the lab using distilled water and so far, I do not see any precipitation. I will be testing the “factory” water for hardness also. I hope I understood your comment right.
@Gunther that looks super interesting to make plant extract. I am planning on purchasing an alembic that runs on a boiler to make hydrosol and essential oils to use the local aromatic herbs that wildly grow here in the mountain. Your diagram looks like an Alembic one or the rotary evaporator (using a solvant like alcohol for the extraction?

Thank you for your feedbacks

I just realized how long is my request. So sorry for the long text
