Hi all, The more I read the messages about soap making, the more I realize that I don't understand the principle of soap making. Can anybody tell me (or give a link) what exactly is saponification ? Do only the FFA's saponify, or the total oil ? If this saponification is well known, why isn't it possible to find out how much lye is needed in an unknown oil (mixture) like WVO ? If somebody ever found out how much lye one needs to saponify (is that the right word ?) for example olive oil, how did he or she do that ? Can't we replicate that method with a mixture of used oils ? Mike wrote that coconut oil could dry out the skin if used to much. Why does it do that ? What happens ? Why doesn't olive oil do that ? Somewhere I also read, that glycerin moisturizes the skin, but if one would use to much in soap, it would work the other way round and dry out the skin. Why is that ?
