I have a question about mixing charcoal powder for soap. When mixing the charcoal into the oils do I take some out from the measured amount for the soap to mix the charcoal in or do I use an additional amount of oil for that purpose? I k ow I’m supposed to mix in the charcoal after I got some trace, but I’m not sure if I’ll ruin the soap if the subtract some oil the the amount then add it back during the trace stage. I hope you can understand my confusion.
