The fun thing about pigments, such as Pearl-ex, is that you can do what
you like with them. You can mix it into the clay, brush it on the
surface before you bake, and brush it on after curing. You can even do
all three on the same piece! It all depends on what effect you wish to
achieve.
The only tip I have about pearl-ex after baking is that it can move
about a bit when you apply a sealant on it. Sometimes thats a good thing
too.

I'm new to polymer clay and am interested in using pigment powder to
get interesting effects. But how do you use it? Should be mixed
through the clay, brushed on a piece before firing, or added after
firing? Any suggestions? Thanks.
