For reference, this is 1 week after making the one tiny test soap of pink sugar fragrance. Taken today with my trusty cell phone (now you know why I don't post pictures of my creations, the
real camera was lost in tornado 2013) No color additives in this soap. The test bar to its left is the wintergreen, patchouli, & ylang ylang. Both were made from the same batter and both still smell great. And please ignore the smooshed edges, I pinched it a little 2 days in to see how soft it was (much softer than the wintergreen one for sure)
ETA - this was at 8 drops in 2 tablespoons batter which today (one week curing) weighs .95 oz. So approximating a pour of 1 ounce that would be .65 oz oil (in this recipe) and .0175 oz scent or 2.7% rate.
