Since prehistoric times, glitter has been made and used as a decoration, from many different materials such as; malachite, galena, mica, insects and glass. Modern glitter is usually made from plastic. The first production of modern (plastic glitter) is credited to the American machinist Henry Ruschmann, who found a way to cut sheets into glitter in 1934. Today over 20,000 varieties of glitter are made in a large number of different colours, sizes, and materials. Over 10,000,000 pounds (4,500,000 kg) of glitter was purchased between the years of 1989 and 2009. Commercial glitter ranges in size from 0.002 square inches (1.3 mm2) to 0.25 square inches (160 mm2). First, flat multi-layered sheets are produced combining plastic, coloring, and reflective material such as aluminium, titanium dioxide, iron oxide, and bismuth oxychloride. These sheets are then cut into tiny particles of many shapes including squares, rectangles, and hexagons. Glitter in little containers.
