Cobalt Name Origins
- meaning
- brief story
- famous historical use of cobalt
- longer story
Cobalt gets its name from the German word Kobold, meaning goblin.
Cobalt ore looks a lot like silver ore but gives black soot and poisonous gas instead of silver!
Cobalt had been used for centuries to color blue the special glass we use to look at an eclipse, and to make cobalt blue pigments, a very stable medium dark blue. German miners named it Kobold ore (Goblin ore) because of all of the mischief it caused when they tried to refine it. As mentioned above, ores containing cobalt looked a lot like silver. The miners would get really excited when they saw this. But, when they refined it, instead of getting beautiful, gleaming, expensive silver after smelting the ore, they were left with a pile of black powder (cobalt oxide). Rocks containing cobalt also tend to have arsenic in them too. Smelting of poisonous arsenic, as you may imagine, has much worse side-effects than just finding black powder in the place of silver.
Cobalt is a goblin. Mischevious, but very rewarding when treated right. It turns out that the comparison of cobalt to a goblin is pretty spot on. In both German and Nordic folktales, the basic gist is that Goblins will be very good to the people that they live with as long as they are treated well. When a goblin feels that he is not treated well, his retribution is swift and stinging.
Nickel Name Origins
- meaning
- where and when
From ‘Kupfer-nickel’, copper of Old Nick.
Named after ‘Nickel’ a mischievous sprite of German mythology (similar to Old Nick).
Nickel ore looks like copper ore but gave miners no copper. In medieval Germany, a red mineral was found in the Erzgebirge (Ore Mountains) that resembled copper ore. However, when miners were unable to extract any copper from it, they blamed the sprite ‘Nickel’ for besetting the copper and called the ore Kupfernickel from the German Kupfer for copper. This ore is now known to be nickeline (aka niccolite), a nickel arsenide.
In 1751, Baron Axel Fredrik Cronstedt tried to extract copper from kupfernickel at a cobalt mine in the Swedish village of Los, and instead produced a white metal that he named after the spirit that had given its name to the mineral, nickel
Aluminium Name Origins
From Alum or Alumen
The ancient Greeks and Romans used alumen (alum, potassium aluminium sulfate, K2Al6(OH)12(SO4)4) in medicine as an astringent, and as a mordant in dyeing.
Alum was exported from ancient Greece and Italy.
