like the black oxide, just a little of this goes a long way. picture attached is using less than half teaspoon per pound of oil. this was my second batch of soap that i ever made, so don't mind the roughness! the black is iron oxide. it's such a rich blue. i love it.
Oh my goodness I'm so happy with this blue, I used it with the fluorescent colors and it's perfect so bright and beautiful.
Love this color! Just a note, because it's natural, it can be stinky while mixing but don't fear! It goes away!
I've used this ultramarine blue in a drop swirl. The swirls look so nice and the pop of color is perfect.
Perfect royal blue! I absolutely love it!!
