'Well nickel carbonyl turned out to be a very volatile colourless liquid, one that boils just below room temperature.' What Mond and his assistant Langer discovered was something remarkable – that his valves were corroding because the metal reacted with carbon monoxide, to make a compound called nickel carbonyl.' And he had a problem – he was passing carbon monoxide gas through nickel valves and these kept failing and leaking. 'Mond was a German chemist who moved to the UK.

But the problem is that in contact with the skin, as in jewellery, the tiny amounts of nickel that dissolves in the sweat of the wearer was enough to cause skin reactions in some people and the using nickel turned out not to be a great idea.' 'Yes, a bit like chrome, but less vulgar – chromium gives a brilliant shine. 'Oh, you mean a bit like chrome plating '. Nickel has long been used in alloys and to plate other metals – the nickel provides a tough resistant and shiny coating that protects the object from corrosion.' 'But isn't nickel rather nasty? Wasn't there some problem with nickel jewellery?' my friend asked.
