Hi all, I want to make a layered soap maybe with activated charcoal. I'd like each layer to look a little bit textured and rustic... specks on each layer of soap to give it a little more interest. I am wondering if I can achieve this with a little bit of activated charcoal mixed in at trace (not completely mixed in to the soap)? I am afraid that it is going to darken each layer instead of having the effect I want. If anyone has tried this or has any other suggestions for achieving what I am trying to do, I'd appreciate it!
