MICA POWDER-PURPLE REDMica Powder is a beautiful bold color of purple that reminds you of fairytales. It is a cosmetic powder for soap making, bath bombs, lip balms, eyeshadows, aroma beads, candles, resin, nail polish, watercolor paints & general crafts. A perfect gift for her Mica is a mineral based powder (frequently used in cosmetics). It does not melt at firing temperatures but rather sticks to the molten glass. For best results, use between glass layers.
