Hi! Thanks for asking. I seem to have forgotten that part in the
instructions! I use spices for color, yes, but they also add a very light
exfoliating effect, and they do add to the fragrance in a hot process soap
(cold process requires that they sit too long with unprocessed lye and they
lose the fragrance, though it doesn't alter the color or exfoliation).
Once your mixture reaches that Vaseline stage and is bland when tested,
stir those spices in as fast as you can. Then go through the process of
your molding and packing. Hope this helps!
