Coconut oil soap

This afternoon I decided to make coconut oil soap. I think it turned out ok for my first attempt but I could have done better.  I combined the lye (sodium hydroxide) and water first. Then dissolved it and added it to my melted coconut oil in a pan on a low heat and stirred it til thick.  I added more water at this point as I wasn't sure if the lye had dissolved.  (This I probably shouldn't have done) I kept it on a very low heat till all the water had evaporated out of it and it didn't 'zing' on my tongue.  I added nag champa oil then let it set.  I'll know whether it's any good after 3 weeks of leaving it to rest.  Apparently one of the problems with this method is that it creates a lot of foam, I live in a hard water area so let's see how it goes and I'll let you know.
