Yeppers. What I do with the gold sparkle mica is mix it with castor oil and swirl instead of soap base. This allows it to keep it's sheen and sparkle instead of going dull by being mixed with the opaque base. The soap absorbs the castor oil pretty well. You can't use alot or it won't absorb it and dry up. So you can see it sort of dents where the gold swirl is. But it gives it an interesting look.
