First off, apologies if this isn't the appropriate place to ask this, let me know and I'll remove immediately.

I recently acquired some Mica Powder Pigments, and they are fun the play with. I mixed some with mineral oil, and some with water. On there own, that's neat. However, if I mix the oil and water (with powder suspended), the pigments tend to mix in the oil, reducing the contrast between the oil and water.

Is there some process I can do that will make one of the pigments hydrophobic and the other oleophobic?

Preferably with "household" items, or easily attainable items, in a DIY/hobbyist environment.
