Traditional Castile bars are made with 100% olive oil, although some soapers consider any soap made with at least 50% to 100% olive oil to be Castiles. In order to avoid confusion over the issue, there are other soapers who call such olive oil-based soaps with less than 100% olive oil, 'Bastiles'. I hope I didn't confuse you!Rebelshope said:Thanks. . . what is castile bar?
