Mixing Micas-With what, and how?

[houseofwool]

OK, one more question-how much? How much mica colors how much soap? And I am assuming I only add just enough liquid to mix with the mica?

Eh, I just eyeball it. I add the mica premixed with water and hand whisk until the color is right. Since they are soap stable, it is pretty much "what you see is what you get".
