I needed some black soap for a project I am working on. I add the Black Brazilian Clay (BBC) first to see how the batter looked with just the clay. It was almost as black as the Activated Charcoal (AC) gives me, not quite as black but almost. I went ahead and add AC to get it up to the black color needed. The acceleration of trace was minimal and the soap turned out great. I will definitely be using this in the future with my darker soaps I want clay in and I will purchase BBC again. Update: I have added a picture of a test batch of soap I made using the various clays I had on hand. The second layer down is made with BBC. I mixed 1.25 tsp of BBC with 1 tbsp of distilled water. I added this mixture to approximately 6 oz of CP soap batter. It came out fairly black with just a hint of brown. For comparison I have added a picture of the striped soap up against a block of CP soap I made with AC and BBC. You can definitely see the brownish tinge in the one that only uses BBC for colorant in the comparison picture.
