Why this list matters
The word
shungite has only existed since 1879. Before that, the rock had been mined, traded, ground into pigment, packed into soldiers' canteens, sold into Imperial cathedral construction sites, sent to the Letniy Sad in Saint Petersburg as carved decorative stone, and used as a household remedy across Karelia for centuries. The people who handled it had names for it. Several names. The names changed depending on who was speaking, what part of the rock-spectrum they were referring to, and which century they were standing in.
This thread collects the names that have been used in the Russian, Karelian, and (via the mineralogical-trade record) Western literature for the same Karelian black-carbon rock. Fifteen distinct terms, each tied to a specific period, source-tradition, or use-case. Reading the names in sequence is reading the social history of the rock in compressed form.
I. The folk-mythological names
1. Аспидный камень, aspid-stone
The 17th-19th-century Russian-and-Karelian folk name. The аспид in Russian folklore is a winged black serpent, a dragon-snake hybrid of pre-Christian or early-medieval origin (the word is borrowed from Greek
aspis but in Russian usage became something larger and stranger than the Mediterranean original). The black, glossy, faintly metallic Karelian rock was named after the creature: dark stone, kin to the dark serpent.
This is the name that frames the rock as something more than a mineral. The аспид serpent is dangerous and powerful; calling the rock its kin places the rock in the same folk-imaginative category. The protective-amulet tradition, the witch's-attribute tradition, the disinfectant-canteen-stone tradition, all of these run through the
аспидный камень frame.
Covered in detail in the
aspid stone folk-name and
vessel of evil spirits and an attribute of sorcerers threads elsewhere in this forum.
2. Змеиный камень, snake-stone
A parallel Russian-North folk-name for the rock, used interchangeably with
аспидный камень. Where
аспид is the specific mythological winged-black-serpent,
змей (zmey) is the more general Russian word for serpent or snake. In northern Russian folk speech, both terms attached to the rock, the rock as kin to the snake, full stop, with
аспид for the high-folkloric register and
змей for the everyday register. The REN-TV regional longread "The Snake Stone: healing properties of shungite few people know about" preserves the name in modern Russian regional press.
The two folk-names map onto the same rock. A Karelian peasant in the 1870s might call it
аспидный камень in front of a priest and
змеиный камень in front of a child. Same rock, two registers.
3. Аспидный сланец, aspid-slate
The same root word (
аспид), applied to the rock in its slate-form (cut and polished as a stone-finish material). This is the form that turns up in 19th-century Russian architectural-trade documentation: floor trim at the Kazan Cathedral, wall-base sections at St Isaac's, decorative vases at the Letniy Sad. When you read a Russian source on Imperial-era cathedral interiors and it mentions
аспидный сланец, it is talking about cut-and-polished shungite-bearing slate from the Karelian deposits.
The Latinised Western-mineralogical synonym recorded in some 19th-century sources is
aspidum.
Covered in detail in the
Karelian shungite-slate in the wall-base sections of St Isaac's Cathedral thread elsewhere in this forum.
II. The Imperial-survey names
4. Чёрная олонецкая земля, black Olonets earth
The 18th-19th-century Russian Imperial mineralogical-survey term. Olonets
(Олонец) was the historical name of the Karelian gubernia, the administrative region containing the shungite belt; the rock was the
black earth of that region. The term appears in the Komarov 1841/1848 reports in the
Mining Journal (Горный журнал, the oldest Russian periodical in the mining-and-metallurgy field, founded 1825). Komarov was the first mining engineer to argue that the
чёрная олонецкая земля deserved formal classification as a distinct material rather than being filed under coal or slate.
This is the workmanlike, observational name. No serpent, no dragon, no folklore, just the geographic origin and the colour.
5. Земляной уголь / углистый сланец, earth-coal / carbonaceous shale
The 1792 terms used by academician N.Ya. Ozeretskovsky during his Imperial Academy of Sciences expedition to Karelia. Ozeretskovsky compared the black Karelian rock to coal and called it
earth-coal, coal-like material that sat in the ground in its black-earth form. He also described it observationally as
carbonaceous shale (углистый сланец), the term that became the more widely-used Russian-academic designation in the 19th century. He noted the rock's distinctive colour, texture, and faint metallic conductivity, and he recorded the local people's use of it. Ozeretskovsky was the first to remark, in print, on the unusually black soil of Kizhi Island specifically, the soil that the later 19th-century geologists would identify as decomposed shungite-shale weathering on the bedrock surface.
Covered in detail in the
1792 explorer who described shungite thread elsewhere in this forum.
6. Землистый антрацит, earthy anthracite
The 1841 term introduced by mining engineer N.I. Komarov. Komarov was attempting to reconcile the rock's apparent coal-family character with its non-coal-like physical properties. He landed on
earthy anthracite as a compromise: a material in the anthracite branch of the coal-family but with the friable, earthy, semi-pulverulent character that distinguishes the Karelian rock from true Donbas anthracite.
The term lasted as the working scientific name in Russian mining-and-metallurgy publications for nearly four decades, until Inostrantsev replaced it in 1879.
7. Шуньгский антрацит, Shunga anthracite
The transitional term used during the 1870s-1880s fuel-trials period, when the Karelian black-rock was being seriously evaluated as a Russian-supply substitute for imported anthracite. The Russian Imperial state had a strategic interest in finding a domestic anthracite source. The Karelian deposit was sampled, tested, and named after the village of Shunga where the most-promising outcrops were exposed. Inostrantsev himself used
шуньгский антрацит in his earliest publications on the rock, before settling on the shorter form
shungite in 1885.
The fuel-trials ultimately concluded that the Karelian rock was unsuitable as anthracite-substitute fuel. The classification problem the trials raised, what the rock actually was, if it was not anthracite, drove Inostrantsev's 1879 monograph and the formal naming.
Covered in detail in the
St Petersburg professor who gave the rock its name thread elsewhere in this forum.
8. Северный антрацит, Northern anthracite
The mid-19th-century Russian-survey term used in the field-notes of geologists
G. Helmersen and
B. Kolenko in their reports on the Kizhi-and-Zaonezhye region. Where Komarov's
землистый антрацит (earthy anthracite) had emphasised the friable-earthy character of the rock,
северный антрацит (northern anthracite) emphasised the geographic-regional origin: this was anthracite from the Russian North, distinct from the Donbas anthracite of the south. The term reflects the same Imperial-state strategic question the
шуньгский антрацит designation reflected, could the Russian North supply a domestic anthracite-grade fuel?, but with a regional rather than a deposit-specific framing.
9. Кижский чернозём, Kizhi black-earth
The local Zaonezhye and Russian-survey term for the unusually black soil of Kizhi Island. Helmersen and Kolenko, the same geologists who used
северный антрацит, used
Kizhi chernozem (Kizhi black-earth) for the surface-weathered form of the rock as it occurs on the island. The bedrock of Kizhi is shungite-bearing carbonaceous shale (the Karelian Research Centre RAS geological survey records the depth profile: 15-25m shungite-bearing rocks, 25-30m gabbro-dolerite intrusion, 30-38m high-carbon shungite-bearing rocks). The surface soil is what shungite-shale becomes when it weathers under wind, rain, and frost cycles for centuries. The local farmers had been working the soil; the geologists were the first to identify what the soil was made of.
The term
Kizhi chernozem is also a wry Russian-mineralogical joke: real chernozem (the black agricultural soil of the Russian steppes) is one of the world's most fertile soils because of its dense humus content.
Kizhi chernozem is black for a different reason, not humus, but carbon, and it is, in agricultural terms, the opposite of fertile. The wooden Kizhi Pogost cathedrals were built on this island in 1714 onwards (covered in the
Kizhi Pogost thread elsewhere in this forum); they are Russian-Orthodox monumental architecture standing on a shungite island.
10. Олонецкая чернедь, Olonets blackness
The natural-pigment trade name for the dye extracted from ground shungite-shale.
Чернедь (cherned) is an archaic Russian word for a black pigment or stable black dye;
олонецкая (Olonets) names the gubernia of origin.
Olonets blackness was used as a textile dye, an iconographic pigment, an industrial paint additive (the artillery-piece blackening covered in the
cannon paint thread elsewhere in this forum used this same pigment trade), and as a printer's-ink component in regional Russian printing-trade documentation. The pigment trade is one of the documented Russian-state-supply uses for which the Karelian peasants brought ground shungite-shale to Saint Petersburg through the 18th and 19th centuries.
Covered in part in the
Cologne earth pigment and
cannon paint threads elsewhere in this forum.
III. The trade-and-craft names
11. Глинистый шифер, clay shale
An older Russian trade-form term for the slate-like sedimentary variant of the rock, recorded in 18th-19th-century construction-and-roofing documentation.
Шифер (shifer) is the Russian word for shale or slate as a roofing-and-building material;
глинистый (clay-like) describes the matrix. The term covers a wider category than
аспидный сланец: it includes Karelian shungite-bearing slate but also non-shungite-containing clay-shale variants from neighbouring deposits.
When you read a 19th-century Russian construction-trade document that mentions
глинистый шифер from Karelia, you should interpret it as "shale-form Karelian slate, possibly shungite-bearing, possibly not". The lithological precision came later.
12. Нигозерский сланец, Nigozero shale
The deposit-specific name for the variant of shungite-bearing rock extracted from the
Nigozero deposit near the village of Nigozero, in the Kondopoga district of Karelia. The Nigozero variant is low-carbon (approximately 1% carbon) compared to the high-carbon Shunga variant (up to 98% carbon). It is the variant that was sent to Saint Petersburg in the early 18th century for the Letniy Sad decorative vases, and it is the variant that the 20th-century Soviet construction industry developed into
шунгизит (shungizite), the porous lightweight concrete-aggregate produced by firing the shale in rotary kilns.
The Russian-language sources note an important terminological confusion: in the 20th century the word
шунгит expanded to cover the full family of Karelian carbonaceous rocks, including the low-carbon Nigozero variant. The result is that modern Russian-trade documentation often uses
шунгит for the Nigozero shale even though the Nigozero variant is geologically and chemically distinct from the high-carbon Shunga variant.
Covered briefly in the
Karelian shungite-slate in the wall-base sections of St Isaac's Cathedral thread.
13. Пробирный камень, touchstone (assayer's stone)
The black-rock-as-precious-metal-test name. A
пробирный камень is the dark, hard, fine-grained stone an assayer uses to test the purity of gold or silver: you rub a sample of the metal across the stone surface, the streak of metallic deposit reads against the stone's dark colour, and the pattern of the streak reveals the sample's purity. The Karelian aspid-stone, in its glossier and harder forms, is one of the rock-types historically used as a touchstone in Russian and Karelian assaying practice.
The Western mineralogical-trade synonyms recorded for the same touchstone-class material include
lidite (from the ancient Lydian assayers) and
paragon (the term used in some 18th-19th-century European mineral-collection catalogues). Russian-language reference works list these as Western synonyms for аспидный камень / пробирный камень / shungite, though the geological precision varies, and not every European
lidite specimen is necessarily Karelian-origin.
IV. The modern scientific name
14. Шунгит, shungite
The name proposed by professor Aleksandr Inostrantsev of Saint Petersburg University in 1879, formalised in his 1885 publication. Named after the village of Shunga in Zaonezhye where the most-cleanly-exposed and most-carbon-rich outcrops are located. Inostrantsev's contribution was to establish the rock as a distinct natural-carbon allotrope rather than a kind of coal or a kind of slate, and to give it a classification-record name in the formal mineralogical taxonomy.
The 1879 paper did not displace the older folk-name
аспидный камень. The two names ran in parallel for decades, in the regional press, the Russian encyclopaedias, and the village folk-memory; to this day, Russian-language regional outlets sometimes lead with
аспидный камень and only afterwards note "also called shungite".
Inostrantsev's name is also what the rock would have been called if the 1879-1885 fuel-trials had succeeded: the project of finding a Russian anthracite-substitute fuel did not work out, but the project of finding a Russian classification-record name for the rock did.
15. Shungite (the international name)
The 1879 Russian name in its Latin-alphabet transliteration, as it entered the Western mineralogical literature in the late 19th and early 20th centuries. The name has been the international scientific term for the Karelian black-carbon rock since approximately 1900. The 1992 fullerene-discovery paper by Buseck, Tsipursky, and Hettich (covered in the
1992 fullerene discovery thread) used the international name; every subsequent Western and Russian academic paper has used the same. The folk name
аспидный камень survives, but in the international scientific literature it is the Karelian rock that goes under its 1879 Inostrantsev name.
How the names overlap
The fifteen names do not refer to fifteen different rocks. They refer to the same Karelian carbonaceous-rock family, viewed from fifteen different angles:
- The
folk-mythological angle (аспидный камень, змеиный камень, аспидный сланец) names the rock by its kinship to the serpent
- The
Imperial-survey angle (чёрная олонецкая земля, земляной уголь / углистый сланец, землистый антрацит, шуньгский антрацит, северный антрацит, кижский чернозём, олонецкая чернедь) names it by region, by coal-family classification, by anthracite-trial designation, by surface-soil expression, and by pigment-trade use
- The
trade-and-craft angle (глинистый шифер, нигозерский сланец, пробирный камень, lidite, paragon) names it by use-case: roofing slate, deposit origin, assayer's tool, mineralogical-collection specimen
- The
modern scientific angle (шунгит, shungite) names it by its 1879 type-locality
Each angle preserves something different. The folk names preserve the serpent-and-otherworld imaginative frame. The Imperial-survey names preserve the geographic, coal-family-classification, and pigment-trade debates. The trade-and-craft names preserve the actual practical uses the rock had been put to before science caught up with it. The modern name preserves the 1879 mineralogical settlement.
Reading a 19th-century Russian source that uses several of these names in the same paragraph, and that does happen, is reading the rock through several superimposed frames at once. The same writer, in the same sentence, might call the rock
аспидный камень in the high-folkloric register,
змеиный камень in the everyday register,
шуньгский антрацит in the technical register,
чёрная олонецкая земля in the survey register, and
олонецкая чернедь in the pigment-trade register. The redundancy is not confusion. It is the rock occupying several social-cognitive categories simultaneously.
The category problem
The reason the rock has fifteen names is that the rock does not fit neatly into any single category in 18th-19th-century Russian-Imperial classification systems.
It is not coal, exactly: it does not burn the way coal burns. It is not slate, exactly: it does not split the way slate splits. It is not anthracite, exactly: it failed the 1870s-1880s fuel-trials. It is not a precious-metal-test stone, exactly: it has uses far beyond the assayer's bench. It is not a soil, exactly: the
Kizhi chernozem is black for the wrong reasons. It is not a pigment, exactly: it has uses far beyond the dye-bath. It is not even one rock, exactly: the high-carbon Shunga variant and the low-carbon Nigozero variant are chemically and geologically distinct, even if both have ended up under the modern umbrella term
шунгит.
The fifteen names are fifteen attempts to fit a rock that resists fitting. Inostrantsev's 1879 contribution was, finally, to invent a new category name,
shungite, that did not pretend the rock was a member of any pre-existing family. The name solved the category problem by creating a category of one.
