Mica Powders are here! Mica Powders are a great way to brighten your stamped images. The mica powders are a wonderful way to create a metallic color within your project. They can be applied to the surface by using the Glass Stamping Medium™. For best results mix a white or black high fire enamel with the Glass Stamping Medium™, stamp your image and let it set, then while it is still tacky, rub the mica powders into the stamped image. When totally dry, wipe off the residue of the mica powder. They also can be fired within the layers of a fused glass project. The mica powders will hold up to fusing temperature 1400 degrees F.
