Karelian shungite was a traded European artist's pigment for centuries under three different names

Three names before "shungite"

The name шунгит (shungite), given by Inostrantsev in 1879, is the rock's scientific-mineralogical label. Before Inostrantsev, the same rock had been in use as a black artist's pigment across Europe for at least two centuries, under three different traditional names:

- Олонецкая земля (Olonets earth), the Russian-language name, used in the 18th-19th-century Russian icon-painting tradition, named after the Olonets gubernia where the rock came from.
- Кёльнише эрде (Kölnische Erde, "Cologne earth"), the German name. This was the trade name under which the pigment circulated in Western European painting markets. The German name suggests Cologne, the major Rhine river-trade city, was the European centre of distribution. The name almost certainly disguised the Russian origin.
- Карельская чёрная (Karelian black), a more modern Russian-popular name preserving the Karelian origin.

The same rock. Three names. One European pigment-trade history that runs from at least the 17th or 18th century until industrial pigment manufacture replaced traditional mineral pigments in the late 19th and early 20th centuries.

Why the rock works as a pigment

Shungite has properties that make it almost ideal as a black pigment for traditional egg-tempera and oil painting:

- Light-fast. Russian-language pigment-handbook descriptions say пигмент шунгит является светостойким пигментом, the shungite pigment is light-fast. Pigments fade or shift colour under prolonged exposure to sunlight; light-fast pigments retain their colour for centuries. Shungite, formed under 2 billion years of geological pressure, is structurally stable enough to survive the comparatively trivial light exposure of a centuries-long church or museum environment.
- High covering power. Шунгит обладает высокой кроющей способностью, shungite has high opacity. A small amount of pigment, mixed with binder, completely covers the underlying surface. This is critical for icon work, where black areas need to be densely opaque rather than translucent.
- Resistant to sulfide-driven discolouration. Шунгит под действием сероводорода и сернистых газов не изменяет первоначального цвета, shungite does not change its original colour under hydrogen sulfide or sulfur dioxide exposure. This is an unusual property. Most lead-based and copper-based pigments react with hydrogen sulfide (which is produced in small quantities by candle combustion, by oil-lamp burning, and by certain microbial activities in old buildings). White lead darkens to lead sulfide; copper greens turn brown. Shungite, which is essentially elemental carbon, does not have a chemical pathway for sulfide attack.

For an icon painting that would hang in a Russian Orthodox church for centuries, surrounded by candle smoke and incense, exposed to whatever sulfurous compounds the burning produced, the choice of a sulfide-resistant black pigment was not academic. The wrong black would turn brown over time. Shungite stayed black.

Mixing with white

The Russian icon-painting tradition records a specific colour effect: в смеси с белилами он дает красивый синеватый оттенок, in mixture with white pigments, it gives a beautiful bluish tint. The bluish-tinted greys produced by shungite-and-white mixtures were used for grey skies, monastic robes, certain shadow areas in faces, and the cool-grey halftones in rendered drapery. This is a small craft fact. It is also a fact that travelled from icon studio to icon studio across centuries, and that a serious 17th-century Russian icon-painter would have known.

The European trade

The "Kölnische Erde" name is the trail-marker for the European side of the story. By the 18th century, German pigment-merchants in Cologne were dealing in a black pigment under that name. The geological-source identification is unambiguous: Cologne earth is shungite, traced through pigment-handbook references back to Karelian Olonets-earth shipments. The trade went via the Rhine, via Hanseatic-network connections, via Saint Petersburg as the Russian shipping hub for goods to Northern Europe.

The pigment was probably never a high-volume commodity. Carbon-based black pigments (lamp black, vine black, ivory black) were easier to produce locally. Shungite's competitive advantage was the sulfide-resistance and the bluish-tint property. For specialised icon and oil-painting work in Northern and Eastern European studios, those properties justified the import of Russian pigment.

The 19th-century Maksovskoe extraction

The mid-19th-century mining at the Maksovskoe deposit (covered in a separate thread) was specifically for black paint pigment. The extraction was small-scale and local, supplying the Russian Empire's industrial-paint and decorative-paint markets. The European pigment-trade demand had probably already declined by then; the major customers were Russian, supplying iron-foundry casting paint, church-railing decoration, and similar industrial uses. By the early 20th century, synthetic carbon blacks (industrial soot derivatives, then engineered carbon-black products from petrochemical processing) replaced the traditional mineral pigment for almost all uses.

The pigment-trade history of Russian shungite is, in this sense, a story of the rock circulating across Europe for centuries under disguised names, then being absorbed into the industrial-pigment marketplace, then being displaced by synthetic blacks, then being re-discovered for completely different reasons in the 20th and 21st centuries. The rock that 17th-century Cologne pigment-dealers were quietly importing under the name Kölnische Erde is the same rock that 21st-century wellness shops sell pyramids of, under a Russian name those Cologne dealers wouldn't have recognised.

Where the trail leads

- Hudsalon.ru, dry mineral pigment shungite product page (still sold today as a traditional artist's pigment): hudsalon.ru

For the European trade history under "Kölnische Erde" / "Cologne earth":

- The trail leads back through the German pigment-trade literature of the 18th and 19th centuries. The standard German pigment handbooks (e.g. Friedlieb Ferdinand Runge's chemistry of dyes and pigments, the Kunsttechnik tradition of artisanal pigment recipes) reference Kölnische Erde. Connecting that named pigment back to the Karelian Olonets-earth source requires reading both ends of the trail. As of writing, no English-language treatment has assembled the full Kölnische-Erde-to-shungite identification chain.

For the icon-craft tradition specifically:

- The Russian icon-painting tradition's pigment knowledge survives in active monastery-school practice (the Holy Trinity-St Sergius Lavra, the Pochaev Lavra, the Kiev-Pechersk Lavra all maintain traditional pigment workshops). Direct monastic conversation in those institutions would be the way to recover the practical use of shungite as Olonets-earth pigment in living tradition.
- The State Russian Museum and the Andrei Rublev Museum of Old Russian Art in Moscow have research divisions that perform pigment analysis on icons. Their pigment-database publications would systematically identify shungite-bearing icons in the surviving Russian-art corpus.

Editor's note (2026 audit): Standard pigment history identifies Cologne earth (Kölnische Erde) as a LIGNITE-derived pigment from German brown coal, NOT Karelian shungite. Thread 238 correctly identifies them as separate competing pigments. Thread 177's 'same rock under three names' framing overreaches. Suggested edit: Reconcile with thread 238: Olonets blackness (shungite-derived) and Cologne earth (lignite-derived) are SEPARATE pigments that competed in European catalogues, not the same rock under different names.
