This is perhaps a silly question ..... normally I just throw my mica straight up to the batter. But I want to do a test for a soap that required many different colors, so I am guessing it will be best to dilute it first. I am tending to dilute it in part of the oil, and subtract it from the batch, or I have some glycerin .... What is you all experience with subtracting the oil? Will that part of the oil not sponcify? Thanks in advance for the help.
