Sparkly mica stars ready to include in your glass fusing projects. These shapes were cut from raw mica and then fired to nearly 1900F to change the color to an assortment of beautiful metallic colors. Mica is an inclusion that must be fused between layers of glass and needs a long bubble squeeze during fusing to prevent large bubbles. Small bubbles are a normal and typical result of fusing with inclusions.
