Powders such as Pearl Ex Powdered Pigments or Perfect Pearls not only add shimmering color and highlights, they even work Cinderella-like magic on humble scrap clay.
Scoop, don’t pour, powder onto scrap paper. Dip your finger in the powder, tap off loose particles, and lightly swab the clay. Use a paintbrush if you want to work powder into stamped crevices. This will send tiny particles afloat, so wear a dust mask. Also stay away from fans, air conditioners, and heat registers.
Apply one or two coats of varnish to seal Pearl-Ex embellished pieces after curing. Perfect Pearls powders do not require a seal, but the surface will feel gritty. A bit of ArmorAll will correct that.
