German Silver: Not German. Not Silver. Possibly Mithril.
Mithril, Moria, and the Devil’s Copper
I’ve spent an embarrassing amount of time thinking about mithril.
Not the movie version — the shiny plot device that saves Frodo’s life in the mines. The canonical mithril. Tolkien’s mithril. The one described with almost metallurgical precision in Gandalf’s words in Moria:
“Mithril! All folk desired it. It could be beaten like copper, and polished like glass; and the Dwarves could make of it a metal, light and yet harder than tempered steel. Its beauty was like to that of common silver, but the beauty of mithril did not tarnish or grow dim.”
Apparently no one truly knows what inspired that description. Mithril is one of the very few things in Middle-earth that Tolkien invented wholesale, with no acknowledged mythological source and no letter, note, or interview in which he identifies a real-world referent. The Tolkien fandom has thought carefully about this — it’s one of the genuinely open questions in a legendarium where most things have documented sources — and the scholarship on Tolkien’s methods of world-building is rich and serious. I’m building on that scholarship, not correcting it. The properties he chose — silver appearance, non-tarnishing, malleable yet strong — are specific enough to suggest something concrete was in his mind. So I went looking for what that something might have been.
My argument is not that mithril is any real metal. It’s simpler than that: Tolkien was a world-builder who transmuted his immediate environment into fiction — he did it with geography, with architecture, with people he knew. The question worth asking is whether he did it with materials too. And if he did, the answer is hiding in plain sight in the city where he grew up.
The usual suspects, briefly
Tolkien scholarship has proposed titanium, aluminium, platinum, and silver as candidates. These are serious proposals from people who thought carefully about the text, and the titanium argument in particular has real intuitive appeal — lightweight, strong, corrosion-resistant. Each fails, though, and not just on physical grounds.
Titanium is very improbable. Pure metallic titanium wasn’t produced until 1910, and when Tolkien began writing in 1937 the entire global supply consisted of small experimental batches produced in a Luxembourg scientist’s home laboratory — by 1938 Kroll had managed just 50 pounds. Industrial production didn’t begin until 1948, the year Tolkien finished writing, at a grand total of 2 tons — a classified strategic material with no public profile as a metal. If “titanium” meant anything to a general reader in the 1930s and 1940s it was as a white paint pigment (titanium dioxide), which had been entering household use since the 1920s — a soft white powder with nothing in common with the lustrous, malleable, silver-coloured metal Tolkien describes. Beyond that, titanium work-hardens rapidly under mechanical stress — it is essentially the opposite of “beaten like copper,” which implies the easy plastic deformation of a ductile metal. On every relevant axis — cultural presence, physical behaviour, visual character — titanium fails.
Aluminium has a more interesting history. For a brief window in the mid-19th century it was more coveted than gold — Napoleon III reserved aluminium cutlery for his most honoured dinner guests while others made do with gold, and France’s 1855 Exposition Universelle displayed aluminium bars in glass cases alongside the crown jewels. In that moment it had exactly the mythic quality mithril carries. But the Hall–Héroult electrolytic process arrived in 1886, and within twenty years aluminium had collapsed from precious curiosity to the metal of cheap pots and mass-produced goods. By the time Tolkien was growing up in Birmingham in the 1890s, aluminium carried precisely the wrong cultural associations — industrial cheapness, not nobility. Polished aluminium can be bright, but it reads distinctly cooler and more bluish-grey than silver; no Victorian would have mistaken one for the other. More fatally for the argument, by the 1890s aluminium was the metal of mass production — the opposite of mithril’s prestige.
Platinum is far too dense. Silver tarnishes — that’s almost the entire point of Tolkien’s comparison. None of these candidates were present in Tolkien’s daily life as a child in any culturally significant way.
German silver
There is one material that was present — ubiquitously, inescapably present — in Tolkien’s Birmingham childhood, that the standard candidate list consistently overlooks. It is called German silver, and it contains no silver whatsoever.
German silver — also marketed as nickel silver, Argentan, and Nevada Silver — is a copper-zinc-nickel alloy developed commercially in the early 19th century. Its name refers to its appearance, not its composition. It was engineered to look like silver, behave better than silver in everyday use, and cost a fraction of silver’s price.
The key ingredient that made it possible — nickel — was once known as the devil’s copper. Medieval German miners in the Ore Mountains kept finding a reddish-brown ore that looked exactly like copper, yielded no copper when smelted, and made the men who worked it violently ill. They blamed a mischievous underground goblin — Nickel, a German diminutive of Nikolaus, related to the English Old Nick — and named the ore Kupfernickel: the devil’s copper. The curse was real. The miners were being slowly poisoned by arsenic trioxide released during smelting, and they had named an entire ore after their supernatural explanation for why it was killing them. It took until 1751 for a Swedish chemist named Axel Cronstedt to isolate nickel as a distinct element — inadvertently preserving the devil’s name in the periodic table, where it sits today as element 28. The same ingredient that poisoned medieval miners is what gives German silver its silver-white colour, its workability, and — most importantly for this argument — its permanent resistance to tarnishing.
The properties that made German silver commercially revolutionary were exactly three: it had the visual appearance of silver, it could be worked and polished like silver, and — the property that drove the entire market — it did not tarnish.
That last point deserves emphasis because it was genuinely remarkable. Sterling silver tarnishes primarily through reaction with sulphur compounds in the air, forming black silver sulphide on the surface. German silver does not. Its nickel content makes the alloy surface electrochemically stable under ambient conditions, producing a self-protecting finish that holds its appearance indefinitely without polishing. Victorian trade literature hammered this point relentlessly because it was the commercial proposition: the appearance of silver, permanently. Hiorns’ 1890 metallurgical survey describes the alloy as valuable for “its white colour, lustre, hardness, tenacity, and power of resisting certain chemical influences.”
Now read Tolkien’s description again: the beauty of silver, could be polished like glass, did not tarnish or grow dim.
The visual-drama properties — the ones that would lodge in a child’s imagination, the ones that make a material feelspecial rather than merely perform well on an engineering test — match with a precision that is hard to dismiss as coincidence.
There is one further detail worth pausing on. “Mithril” is a Sindarin compound: mith meaning “grey” or “light grey,” and ril meaning “glitter” or “brilliance.” Tolkien named his fictional metal after its appearance — cool grey brilliance. This is a more accurate description of German silver’s optical character than it is of actual silver. Sterling silver has a warm, slightly yellow-white tone. German silver, because its nickel content shifts the alloy’s reflectance toward shorter wavelengths, reads distinctly cooler and greyer under most lighting conditions. The name Tolkien chose for his fictional metal describes the appearance of German silver more precisely than it describes the appearance of silver itself.
A history worth knowing
German silver did not begin in Germany, and it took Europe a thousand years of embarrassment to figure out how to make it.
The Chinese had been producing a white copper alloy called baitong — literally “white copper” — for centuries, reliably documented from around the 3rd century AD and possibly much earlier. It was a copper-nickel alloy, and Chinese craftsmen were smelting nickel-bearing ores and producing a lustrous, silver-white metal long before European metallurgists had any idea nickel existed as a distinct element. European traders encountered it through the East India trade routes and brought it back as a curiosity under the Cantonese romanisation paktong or packfong. They admired it, coveted it, bought it, and for centuries could not work out how to make it themselves. The alloy Europeans eventually called German silver was Chinese technology, independently rediscovered fifteen hundred years later.
The reason Europe couldn’t replicate it was nickel — the devil’s copper, as we’ve seen. Once Cronstedt isolated it in 1751 and the element was understood, German and French metallurgists began systematically developing copper-zinc-nickel alloys. The alloy was refined and commercialised through the 1820s and 1830s under a proliferation of names — Argentan, Neusilber (”new silver”), Maillechort, Alpacca, Nevada Silver, Victoria Silver, Alfenide, Electrum — each designed to evoke silver without legally claiming to be silver. The naming chaos was entirely deliberate. Every trade name was a piece of commercial camouflage, projecting nobility and preciousness onto an alloy whose whole point was that it was cheap. The marketing of German silver is one of the more brazen exercises in 19th-century commercial euphemism: an industry built on calling things by names that meant something they were not.
The name “German silver” itself followed the same logic, acknowledging the country of commercial development while the “silver” referred purely to appearance. By the time Birmingham took over as the world’s dominant production centre in the mid-19th century, the alloy was being sold under so many names that consumers had little idea what they were buying — only that it looked like silver, held its shine, and cost considerably less.
Birmingham in the 1890s
Here is why this matters beyond a properties checklist.
Birmingham in the 1890s was the world centre of German silver manufacture. The alloy had been commercially dominant in British silverware since the 1820s, and by Tolkien’s childhood it was the material substrate of Victorian household life: the base metal of domestic cutlery, decorative goods, plated ware, candlesticks, picture frames, and the hardware of daily existence. It was not a specialist or industrial material — it was what the spoons were made of. A boy growing up in Birmingham between 1896 and 1900 would have encountered German silver every day of his life without ever thinking about it consciously.
And that is exactly the kind of influence that shapes a writer’s imagination. Not a deliberate reference, not a conscious choice, but the ambient texture of the world — the look and feel of things that were simply there, absorbed without being catalogued. Tolkien was not designing an alloy when he described mithril. He was remembering, at some level he could not have articulated, what it felt like to live in a city where the most celebrated material was a silver-coloured metal that never lost its shine.
The pattern of transmutation
This argument does not stand alone. It fits within a pattern of local influence that Tolkien scholarship has long recognised, even where Tolkien himself rarely confirmed it directly.
The Shire is Sarehole — the small Worcestershire village where the Tolkien boys played from 1896 to 1900, which he described near the end of his life as “a kind of lost paradise.” The mill at Hobbiton is Sarehole Mill; Tolkien drew it with its distinctive chimney-tower in his own illustrations. The miller’s son (George Andrew) who chased them off the grounds and was nicknamed the “White Ogre” became Ted Sandyman. Moseley Bog, where they played, became the Old Forest. His aunt Jane’s farm in Worcestershire, literally called Bag End, gave Bilbo his address. The Black Country — the industrial region visible as a smouldering, smoke-stacked horizon from Sarehole’s fields — maps onto Mordor in vocabulary, atmosphere, and name (Mordor means “Black Land” in Sindarin). Perrott’s Folly and the Edgbaston Waterworks tower, two landmarks Tolkien passed daily on his route to school in Edgbaston, are associated with the Two Towers. The illuminated face of the Chamberlain clock tower at the University of Birmingham is linked to the Eye of Sauron.
Tolkien was careful, for the most part, not to confirm these correspondences. He objected to allegory and was protective of his mythology’s internal coherence. But the pattern is too consistent to be accidental, and Tolkien scholarship has long operated on the sensible premise that undocumented influence is still influence. He didn’t need to consciously encode Sarehole as the Shire — he needed only to have lived there intensely as a child.
The same logic applies to German silver. He didn’t need to think “I shall base mithril on this alloy.” He needed only to have grown up in the city where it was made, used it every day at the table, and carried somewhere in his imagination the concept of a silver-coloured metal that never tarnished and that everyone wanted.
The irony at the bottom of the Shire
There is one further connection worth noting, not as a causal claim but as a piece of historical irony that reflects how thoroughly Birmingham’s metalworking identity permeated even the places Tolkien loved most.
That chimney on Sarehole Mill — the architectural feature that made it visually distinctive, the one Tolkien drew faithfully into every illustration of Hobbiton, the emblem of his pastoral ideal — exists because Matthew Boulton put it there. Boulton, the founding figure of Birmingham’s industrial metalworking economy and business partner of James Watt, leased Sarehole Mill from 1756 to 1761 and converted its machinery for metal rolling to produce sheet metal for button manufacture. He later moved operations to the Soho Manufactory at Handsworth, which became the direct ancestor of the Birmingham firms that dominated German silver production throughout the 19th century.
Tolkien almost certainly never knew any of this — Boulton’s tenancy predated his childhood by 135 years, and he wasn’t encoding industrial history, he was encoding a place he loved. But the chimney he loved was a metalworker’s chimney. The “lost paradise” he set against the industrial horror of Birmingham was itself, in its own architecture, a product of Birmingham’s industrial tradition.
Tolkien constructed the Shire and Mordor as opposites. The physical record suggests they were always the same place, seen from different angles and different centuries.
Celebrimbor’s name
One quiet piece of supporting evidence, for those who follow Tolkien’s linguistics.
Celebrimbor — the Elven-smith of the Second Age, the master craftsman who forged the Rings of Power and is associated in the legendarium with mithril-working — bears a name Tolkien constructed in Sindarin to mean Silver Hand. The greatest metalsmith in Middle-earth, the maker of its most prized substance, is named from a root meaning silver.
Tolkien’s naming was never casual or accidental. Mithril itself translates as “grey glitter” — cool grey brilliance, not warm white. Celebrimbor translates as Silver Hand. The craftsman who worked the grey-glittering metal is named for silver. The entire linguistic cluster around mithril points toward silver as its conceptual origin, while the physical description points toward something that improves on silver. A material that looked like silver, worked like silver, but never behaved like silver — never tarnishing, never losing its grey glitter — is exactly what German silver was, and exactly what mithril became in the imagination of a writer who grew up surrounded by it.
What this argument is and isn’t
To be precise about the claim, because the Tolkien fandom deserves precision:
The Tolkien scholarship that takes this kind of argument seriously has good foundations. Tom Shippey, whose work on Tolkien’s sources remains the standard, has documented extensively how Tolkien transmuted real philological and cultural material into secondary-world invention — not as allegory, which Tolkien explicitly rejected, but as what he called applicability: the way real experience shapes imagination without dictating meaning. The literary source for mithril’s narrative function — impenetrable armour of miraculous lightness — is almost certainly the silken mail coat in the Norse Hervarar saga, a text Tolkien knew intimately. That source explains what mithril does in the story. What it cannot explain is why Tolkien described it the way he did: the specific cluster of visual and material properties that make mithril feel real rather than merely functional. That is where Birmingham comes in.
This is not an argument that mithril is German silver, or that Tolkien consciously modelled one on the other, or that the physical properties match on every criterion. Some do not — mithril’s extreme lightness and its hardness exceeding tempered steel go well beyond anything German silver achieves, and that’s as it should be. Fantasy takes real things and removes their limitations. That is the direction of travel from German silver to mithril: take the material that amazed people in Victorian Birmingham — silver appearance, permanent lustre, workable and beautiful — strip away the mundane constraints of actual metallurgy, and you have a legend.
The argument is that German silver was the most culturally prominent material in the city where Tolkien spent his formative years; that its defining properties — the ones that made it remarkable to non-specialists, to households, to children — are precisely the properties Tolkien chose to mythologise; that Tolkien is independently documented as a writer who encoded his Birmingham environment into his fiction with extraordinary fidelity; and that no other proposed candidate for mithril’s inspiration satisfies all three of these conditions simultaneously.
Tolkien never said. But the city he grew up in did.
The minerals behind the alloy
German silver is built from three elements, each with its own story in the earth:
Native copper (Cu) — occasionally found as pure metal in nature, the first metal humans ever worked. Its malleability is what Tolkien captures in “beaten like copper” — a property so characteristic it became the benchmark.
Smithsonite (ZnCO₃) — the principal carbonate ore of zinc, named for James Smithson, founder of the Smithsonian Institution. Zinc contributes brightness and corrosion resistance to the alloy.
Pentlandite [(Fe,Ni)₉S₈] / laterite — the primary nickel-bearing ores. Industrial-scale nickel extraction was one of the defining metallurgical achievements of the 19th century. It was nickel that gave German silver its silver-white colour, its hardness relative to precious metals, and — most importantly — its non-tarnishing character. Without industrial nickel, there is no German silver. Without German silver, there is no obvious real-world seed for the most celebrated fictional metal ever invented.

I did not know until today that JR Tolkien lived in Birmingham for most of his childhood, and for part of that time in Kings Heath, about 500 metres from where I lived. I probably delivered newspapers to houses in that street when I was 13 or 14. Quite a few years after he died though 😁
