Glitter describes an assortment of very small (roughly 1 mm²) pieces of copolymer plastics, aluminum foil, titanium dioxide, iron oxides, bismuth oxychloride or other materials painted in metallic, neon and iridescent colors to reflect light in a sparkling spectrum. Glitter is usually sold and stored in canisters somewhat similar to salt shakers, which have openings that control the flow of glitter. These canisters may contain one or many colors. It can be permanently applied with strong glue, or temporarily applied with other sticky materials, such as makeup. It is not to be confused with confetti, which contains larger pieces, and should also not be confused with sequins, which are larger yet.
Glitter is used in craft projects, especially for children, because of the brilliant effects which can be achieved relatively easily. Glitter is used as an element of decorations, and can be added to rubbers and plastics. It is also often put into cosmetic products like lip gloss and eyeshadow. Glittery cosmetics are popular with youth, but are also worn by adults.
Glitter was invented by Henry Ruschmann. Accounts conflict as to when glitter was invented—some say 1934 and others shortly after World War II.
The word "glitter" is often used euphemistically to refer to brilliantly gorgeous but superficial glamour. From this meaning comes the term glitterati to refer to pop stars and socialites. The word is derived from "glitter" and "literati".
