Black is one of those colors I don't use very often in color schemes with my soaps, but when you need a good black, it's an absolute necessity! There's always the option of using activated charcoal, but AC can speed up trace, and with some FO's & designs, you want to use a colorant where you'll have full control over your trace. I had a black mica from a different supplier and was disappointed with it... No matter how much I added, all I was getting was more of a charcoal gray-type color, not a true black. I decided I'd grab a sample size of this Nocturnal Black mica & was thrilled with the results! FINALLY a dark, TRUE blackest-black where I didn't have to add an excessive amount to get the best results! 1tsp/PPO was MORE than plenty to give me a highly-pigmented black that stayed true in my CP soap! Looks stunning in MP as well! I don't use black very often in my soapy projects, but when It's an absolute MUST that I get a rich black color that won't affect trace and produces exceptional results, THIS is the black I'll reach for!
