When water temperature has lowered to 60 degrees slowly pour in sodium hydroxide and stir. When sodium hydroxide mixture has reached 110-125 degrees slowly add to your melted fat/oil. Using an emersion blender, blend mixture until it starts to become thick. Add essential and castor oils stir in and pour into mold. Cover with cardboard then large towels or blanket to insulate. Wait 24 hours or until completely cool. Cut into bars, let cure in open air for 4 weeks and enjoy.
