Олонецкая чернедь (Olonets blackness) is one of the fifteen historical Russian-and-Karelian names for shungite-bearing rock (catalogued in the
fifteen names for one rock thread). The name applies specifically to the rock's use as a pigment-trade material: ground shungite-shale, sold as a stable black dye, with a regional brand-name attached.
Avdei Aleksandrov, 1750
The earliest dated documentary trace of the Olonets pigment as a tested-and-graded trade material is from 1750. A Russian-state-archive testimony of that year names
Avdei Aleksandrov, a
"window-frame and painting master" (оконишный и малярный мастер), as the craftsman who tested the Olonets black paint and reported on its quality. His positive testimony moved the pigment into the Imperial state-supply category, Imperial buildings, military equipment, ecclesiastical commissions.
Roman black, Cologne black, Olonets black
By the late 19th century, European pigment catalogues listed three regional black-earth pigments together as the principal organic-black trade options:
-
Roman black, ground lignite from the Verona region, in trade-use since the 15th century. The standard reference black
-
Cologne black, ground lignite from the Cologne / Kassel regions, in trade from the 17th century. Slightly browner
-
Olonets black, ground Karelian shungite-shale, in trade from the 18th century. A depth-of-blackness the lignite-pigments couldn't match
Three pigments, sold as parallel options in late-19th-century catalogues. A painter could specify Roman, Cologne, or Olonets black depending on hue, supply chain, price.
The Olonets pigment disappeared from European catalogues in the early 20th century, replaced by industrially-manufactured carbon-black pigments synthesised from oils and gases.
The pigment-trade uses
Olonets blackness, in its 18th-and-19th-century supply period, is documented behind several specific applications:
- Russian Orthodox iconographic painting (Olonets-region workshops had local access)
- Textile dyeing (stable dark-cloth dye, fast under washing)
- Artillery-piece blackening (covered in the
cannon paint thread)
- Printer's-ink component for state-supply printing (banknotes, official documents)
- The folk-decorative
Олонецкая роспись (Olonets painting) tradition on wooden objects and household items
The chemistry that the pigment-makers did not know about
The Olonets pigment is, in 21st-century chemical-classification terms, a natural fullerene-and-graphene-quantum-dot-bearing carbon-black pigment. The Karelian shungite-shale's high concentration of natural C60 and C70 fullerenes (1992 Buseck-Tsipursky-Hettich, covered in the
1992 fullerene discovery thread) and natural graphene quantum dots means that Olonets blackness, ground and applied to a surface, deposits a pigment-layer containing these molecular structures.
Avdei Aleksandrov in 1750, the icon-painters across the 18th-and-19th centuries, the European pigment-catalogue paint-manufacturers, they specified Olonets black for its visual-and-trade qualities. The molecular content was incidentally bundled with the trade goods. Russian Orthodox icon-painting therefore unwittingly deposited natural fullerenes onto wooden panels for centuries. The iconographic record contains, in trace quantities, the same molecular structures the 1992 discovery paper isolated from the rock that supplied the pigment.

Editor's note (2026 audit): This thread (correctly) treats Cologne black as lignite-derived German pigment separate from Olonets blackness. Thread 177 overreaches by claiming they were the same rock under different names. Suggested edit: Reconcile with thread 177: this thread's framing (separate competing pigments) is the more accurate one.
