![]() Trying to dissolve his gunk in alcohol, though, revealed a deep purple liquid. After repeated failures, “Perkin produced little more than a black, sticky mess,” says the Independent. In 1856 Perkin, now 18, was trying to synthesize quinine in the lab. But cinchona trees come mostly from South America, and scientists wanted a better way to get their hands on the drug.Įnter William Perkin, a young chemist who had joined the Royal College of Chemistry at 15. Scientists had recently realized that quinine, a chemical derived from the bark of cinchona trees, could be used to treat against malaria. The Empire’s colonization attempts, though, were being beaten back by malaria. In the 1850s the British Empire was pushing into Africa. But the development of an artificial purple wasn’t a deliberate decision, but a happy accident for a young chemist named William Henry Perkin. The video explains that snail-fueled purple persisted until chemists learned to make synthetic dyes. The craftsmen were harvesting chemical precursors from the snails that, through heat and light, were transformed into the valuable dye.īut this telling leaves out one of the best parts of the story. The snails, though, aren’t purple to begin with. They were then boiled for days in giant lead vats, producing a terrible odor. ![]() To make Tyrian purple, marine snails were collected by the thousands. The video above, by CreatureCast, recounts the story of Rome’s vaunted Tyrian purple, and the color’s close link with the marine snail Bolinus brandaris. Purple was expensive, because purple dye came from snails. And while purple is flashy and pretty, it was more important at the time that purple was expensive.
