I got a small sample bag of C.S. mica with my last order (its so super nice of Nurture Soap to give away goodies!!) At my first try I used just a very small percentage rate of C.S. on my cp-soap and it turned out as a soft, light grey. very soft and elegant! For the next batch I used celestial silver on the main batch again at a very low percentage rate so it would give the soap a lighter colour, and as a contrast I mixed another, smaller container using a higher percentage rate so it would turn out darker. I hanger swirled everything and the next day when I was cutting the soap, I couldn't be more happy! The final color (after gel phase) has so many shades, it really depends on how the light hits the surface- blue, purple, silver or grey- its just amazing!! I tried to take some pictures, but the pics really don't give this amazing mica the true credit it deserves! I'll keep this one in my all-time mica collection, and I recommend it to YOU a thousand times, I really do!
