If you make up extra of say lip balm or lotion bar base, can you just "scoop" out some of the mixture and melt it if you just need a little bit, or is it necessary to re-melt the entire mix? Someone told me once that you should re-melt the entire mix to ensure the oils were properly distributed because some of the heavier oils would settle first. Is this true? I would like to be able to scoop out a little, add my EO's and pour into the mold or tube and be done. It would make my life much easier.
