You will need:
Step One: Pour a variety of colors and swirls for a basic bar. After de-molding your melt-and-pour soap, spray with rubbing alcohol to create a slick surface for rubbing in the pigment.
Step Two: Using a mini-scoop, tap a very small amount of opalescent green mica on a paper towel and then rub all over the surface of your soap. Repeat with the heavy gold mica. The deep parts of the detail in the soap will contrast beautifully against the higher surface that catches the pigment.
Before and After. Less is more! I like to apply the gold in patches on top of the opalescent green mica to create depth.
