Wow!  I just finished making a pure goat milk soap with rose essential oil.  It is awesome!  I experimented with the temperature of the lye and goat milk - keeping it cool.  This was an exercise in patience as it took at least an hour to add the lye.  Let me tell you, it was worth it.  The resulting soap is pure creamy white  I added shea butter and apricot oil too.  This soap is serious luxury!
