Mica powder is crafted of a natural stone mineral that has a metallic sheen to it. When ground into a powder, it has the ability to give your every craft a light-catching something extra. These powder pigments can be mixed with all casting resins, or in other creative uses such as oils, acrylics, slime, soap and polymer clay, fused glass, tumblers or spread dry on porous surfaces. You can even blend colors together to create custom shades and develop one-of-a-kind crafts. When youre done, simply place the cap back onto the container and youll be ready to move on to the next color or project. The colors of our Mica Powders Set are so vibrant, you can easily create bright bath bombs, colorful paintings, mixed media pieces, candles, slime, wax melts and more.
