Medieval Soap Factory Found in Israel
A 1,200-year-old soap factory has been unearthed in the Negev Desert by a team of Israel Antiquities Authority researchers, with the assistance of local high school students. The pillared building was in use during the time when the Abbasids controlled the area.
Based on the archaeological remains, it appears that hard cakes of soap was made from olive oil and saltwort, using a rather complicated process. First, the liquid mixture was cooked for about seven days, and was then transferred to a shallow pool, where the soap hardened for another ten days, until it could be cut into bars, which dried for another two months. So much soap could have been produced at the site that it was probably exported to Egypt and other parts of the Arab world.
