The firs time may be of soap was finded was when the salve observed near of river Tiber that mix beetwen of animal fat of sevearals sacrificed animal was mixed with ashed of wood of the ceremonial fires. The salve notice its property ti clear their hands and the clothes.

If you want to have the first experiences doing yourself soap you need olive oil, water, sosa, flour and salt, besides if you wish that its leave your skin feeling soft you can add escencial oil and with this your soap have a good smell.

I hope you try and have a great shower fos test it.
