I have some activated charcoal in nugget form. (for aquarium filters) I want to make some soap with black swirled into it. My problem is that I don't have a coffee grinder to grind it into powder. I only have a blender and a food processor. I'm wondering if I could try to "infuse" the charcoal nuggets into some oil. Has anyone tried that? I really doubt it would work because it's not like it turns my aquarium black!
