Glitter

Glitter is an assortment of flat, small, reflective particles that are precision cut and come in a variety of shapes, sizes, and colors. Glitter particles resemble confetti, sparkles and sequins, but are somewhat smaller. Since prehistoric times, glitter has been made from many different materials including stones such as malachite, and mica, as well as insects and glass. Uses for glitter include clothing, arts, crafts, cosmetics and body paint. Modern glitter is usually manufactured from the combination of aluminum and plastic, which is rarely recycled and can find its way into aquatic habitats, eventually becoming ingested by animals, leading some scientists to call for bans on plastic glitter.
