In Ytterby you will find two secret pasts. 220 years ago, the sleepy village now dotted with vacation houses owned by wealthy citizens of nearby Stockholm would be a restless mining settlement, shipping out high-grade feldspar for that royal porcelain industrial facilities of Europe and quarta movement to line the blast furnaces popping up across England. It's also the birthplace of a number of character s most marvelous and least appreciated chemical elements.

The second story started in 1787, when a novice geologist named Carl Arrhenius was going to a mine in Ytterby. He discovered an abnormally heavy black rock one of the grey outcroppings and, as being a guy of healthy scientific curiosity, sent an example for analysis to Johan Gadolin, a prominent chemist in the Royal Academy of Turku in Finland. In 1794 Gadolin came to the conclusion the specimen contained a completely new element, later named yttrium. By 1879 chemists had isolated six additional components from exactly the same rock, getting the grand total within the recently invented periodic table to 70. Three of individuals elements ytterbium, erbium, and terbium were simply given additional variants about the title of Ytterby, as the other three were named holmium (for Stockholm), scandium, and thulium (both in the Latin for Scandinavia), within the nationalistic fashion then for. Following a lengthy, lucrative run, the Ytterby quarry was closed in 1933. In lots of ways, though, the city s influence looms bigger than ever before. The sun and rain discovered there, known with each other as rare earths, today make up the backbone from the modern wired and wireless world despite the fact that you've most likely never heard about them.

The nice and cozy glow of terbium is important to high-efficiency compact-fluorescent lights. Europium is broadly used to create vivid shows for laptops and wise phones. Rare earths also appear in additional unpredicted places like baseball bats, European currency, and evening-vision goggles...
