chromium: a thoroughly modern metal | dartmouth toxic metals

Beginning with the use of chrome plating in the art deco designs of the 1930s through its heyday in the cars, furniture and appliances of the 1950s and 1960s, chromium has been closely associated with the fast-paced modern world. Unlike other metals, chromium had no ancient or prehistoric uses

High amounts of chromium are found naturally in two minerals. The more common, called chromite, is a dark, dull stone that was easily overlooked. The second, a mineral called crocoite, is unusual in appearance but extremely rare. Crocoite, also known as lead chromate, was discovered by a geologist in 1765 at the Beresof mine near Ekaterinburg, Siberia. A brilliant orange, the mineral was prized by early stone collectors for its four-sided crystals. Artists also treasured fragments of crocoite for their beautiful, reddish orange color. But the ore is too rare to be useful commercially. Chromite, the primary commercial ore, was not discovered until 1798

The chromium element was isolated in 1797 by the French chemist Louis Nicholas Vauquelin. He named the element from the Greek word for color, “chroma,” because each chromium compound he produced was a brilliant color. He found reds, bright yellows and deep greens and discovered that traces of chromium in a Peruvian emerald were responsible for its color. Others later discovered that the ruby also takes its red color from chromium

In 1799, a German chemist living in Paris found chromium in a dark, dull stone that would become to be called chromite. This mineral was more plentiful than crocoite and the greater availability of chromium facilitated innovation and discovery in a wide range of industries

The colorful chromium chemicals for which Vauquelin named chromium soon found practical application in the textile industry. Before the advent of synthetic dyes, all dyes came from natural sources such as minerals and plants. Often these dyes faded quickly if the dyed material was laundered. To fix or stabilize the color, chemical agents called mordants were used. Chemically, the mordant binds with the dye and the fibers of the material, preventing bleeding and fading. As early as 1820 the cotton and wool industries were using large amounts of chromium compounds such as potassium bichromate in the dyeing process. Red and green pigments developed from chromium compounds were also used for printing wallpaper during this period

In 1822 one of Vauquelin’s pupils, Andreas Kurtz, moved to England and began producing potassium bichromate and selling it to the English textile industry at 5 shillings a pound. Local manufacturers soon followed suit and competition drove the price down to 8 pence, about an eighth of the original price. This did not give Kurtz a satisfactory profit, so he began producing other chrome compounds, specifically chrome pigments. His chrome yellow achieved vogue status when the popular Princess Charlotte, daughter of British monarch George IV, had it used to paint her carriage. This was perhaps the origin of the “yellow cab,” an idea exemplified today in New York City taxis. Kurtz left his mark on the world of color; “Kurtz yellow” is still available in British color catalogues
