For those of us not growing up in a country where nickel could buy you lollies at the milkbar on a Saturday, you may not have been introduced to this metal until now! Nickel is a very popular choice for traditional door hardware … but why? And wherefore? And how come?
Nickel is chemically close to iron, and is produced in the universe by much the same forces. Along with iron, it is formed by much smaller and lower temperature stars than other metals (read: less heat and energy, on Earth!), and as such is very common in meteorites … and in the Earth’s crust, where anybody might pick it up and take it away.
While nickel is quite reactive – being easily damaged when it is in its pure form – the element is quite slow to react with air, so it doesn’t easily develop the patination that brass does, or bronze or iron do, in the forms of verdigris and rust respectively. Nickel is also capable of taking on a very high polish – this is the characteristic that really helped it rise to metal prominence. It is a prince among metals, at least, if not a king!
Nickel is actually magnetic – one of the few metals other than iron that can claim this. While the US nickel is actually 75% copper, so won’t stick to itself in your wallet, or wreck your credit card encoding (!), the Canadian nickel minted between 1922 and 1981 was nearly pure nickel. Not great for credit cards, or the occasional floppy disk that you might find in your wallet!
If you have nickel door hardware in your traditional home, then your knobs and knockers’ metallic cousins include things like Raney nickel, used in chemical reactions in laboratories; kupfernickel (the Devil’s nickel!), which is used to color glass green for beer and other funny coloured drinks; coins all over the world (the rich relatives); and of course, construction and magnets. I like the idea of the Devil’s nickel best… >:-D
Some unlucky individuals are actually allergic to nickel – it can cause mild contact dermatitis if you wear earrings made of nickel and you are sensitive to it. The good news is though, that if it merely on your doorknobs, you are unlikely to suffer any adverse affects from it. If you are concerned, you can easily lacquer your knobs with the appropriate commercial product, and you need worry (and itch!) no longer.
And that is the story of ‘Saint Nick’! Except of course, the many different stories told by the fascinating and individual knobs and knockers in the products section
