Invention of Carbon Pigment

There are pigments with interesting origin stories. Then there is carbon black — a pigment so old, so universally used, and so quietly essential that most people encounter it dozens of times a day without registering it at all.

The ink in the text you are reading right now likely contains it. The tyres on every car on the road contain it. The mascara in most makeup bags contains it. Carbon black is simultaneously one of the oldest manufactured materials in human history and one of the most produced industrial chemicals in the world today.

What Carbon Black Actually Is

At a chemical level, carbon black is a form of nearly pure elemental carbon — tiny particles produced by the incomplete combustion or thermal decomposition of hydrocarbons. The particle size is extraordinarily small, often in the range of 10 to 500 nanometres depending on the production method. That small size is part of what makes it such an effective black pigment — the particles absorb virtually all visible light, producing a deep, consistent black across almost any medium they are applied to.

Carbon pigment in its most basic form is carbon. What varies between different grades and types of carbon black is particle size, surface area, and the manufacturing process used to produce it. These variables determine whether a particular carbon black is suited for use as a printing pigment, a rubber reinforcing agent, a conductive material, or a UV stabiliser in plastics.

The historical forms of carbon black — lamp black, bone black, vine black, ivory black — were all variations on the same basic chemistry, produced by burning or charring different organic materials. Modern industrial production is more controlled, but the underlying substance is the same black pigment that ancient Egyptian scribes used for writing on papyrus thousands of years ago.

The History of Carbon Black as a Pigment

The history of pigments almost always starts with carbon. Before artists had access to iron oxides, lapis lazuli, or lead white, they had charcoal and soot — crude forms of carbon pigment that could be ground, mixed with fat or water, and applied to surfaces.

Archaeological evidence of black pigment use goes back over 30,000 years to cave paintings in France, Spain, and elsewhere. The artists at Lascaux and Chauvet used charcoal-based black pigments to draw the animals that have survived on cave walls into the modern era.

In ancient Egypt, carbon pigment was used extensively for writing ink. Scribes mixed finely ground soot or charcoal with water and a binder — usually gum arabic — to produce the black ink used across papyrus documents. This formula was simple, effective, and produced a durable black line that has survived in readable condition for thousands of years.

In ancient China, ink production developed along similar lines. Ink sticks made from compressed soot and glue became a cornerstone of Chinese calligraphy and painting from very early periods. The quality of the carbon pigment, how finely it was ground, and what materials were burned to produce it were matters of considerable craft attention.

Across the ancient Mediterranean, lamp black — produced by collecting the soot from burning oil lamps — was used in cosmetics, inks, and paints. Kohl, the eye cosmetic used across ancient Egypt and the ancient Near East, was typically a mix of carbon black pigment with other dark minerals.

How Industrial Production Changed Everything

The history of carbon black as a pigment takes a significant turn in the industrial era. Until the 19th century, production was essentially artisanal — burning specific materials in controlled conditions and collecting the soot.

Industrial production changed the scale and consistency of carbon black manufacturing dramatically. Modern methods include:

• Furnace black process — the dominant production method today, producing most of the world’s industrial carbon black by burning heavy aromatic oils in a high-temperature reactor with a limited air supply
• Channel black process — an older method where natural gas is burned and the soot collected from steel channels; largely superseded by the furnace process but historically important
• Thermal black process — decomposing natural gas by heat without combustion, producing coarser particles used in specific applications
• Acetylene black — produced from acetylene gas, with particularly high conductivity used in battery electrodes and conductive rubber

Where Carbon Black Pigment Is Used Today

The applications of carbon black split into two main categories: reinforcing agent and pigment.

The largest single use globally is as a reinforcing filler in rubber — primarily tyre manufacturing. Carbon black added to rubber compounds significantly increases tensile strength, wear resistance, and durability. Without it, car tyres would wear out in a fraction of their current lifespan.

As a black pigment specifically, carbon black pigment appears in:

• Printing inks — for newspapers, packaging, and commercial printing. The deep, consistent black of newsprint ink is carbon black.
• Paints and coatings — in both decorative and industrial applications, as the primary source of black colouration
• Plastics — both as a pigment and as a UV stabiliser that prevents plastic degradation from sunlight
• Toners and inkjet inks — the black toner in laser printers and the black ink in inkjet cartridges both use refined grades of carbon black
• Cosmetics — mascara, eyeliner, and kohl products still use carbon black pigment as their black colourant
• Artists’ materials — lamp black and ivory black in artists’ tube paints are all carbon black pigment in different formulations

Carbon Black in Fine Art: What Artists Should Know

For painters and printmakers, the different historical forms of carbon black behave differently on the palette and in the painting.

Lamp black — made from soot — has an extremely fine particle size and produces a very deep, slightly warm black. It tends to dry slowly in oil because of its high oil absorption.

Ivory black — historically made from charred bones or ivory — has a slightly brown undertone and is considered warmer in tone than lamp black. It is the most commonly available black in traditional oil paint ranges.

Vine black — made from charred grapevine residue — has a blue-grey undertone and is particularly valued in watercolour.

Mars black — a synthetic iron oxide black rather than a carbon black — is cooler, more opaque, and faster-drying than the carbon blacks. It is often preferred for underpainting.

Frequently Asked Questions

What is carbon black and how is it different from other black pigments?

Carbon black is a fine powder consisting of nearly pure elemental carbon, produced by the incomplete combustion or thermal decomposition of hydrocarbons. It differs from other black pigments like iron black or manganese black in that it is purely carbon-based. It absorbs virtually all visible light, making it one of the deepest and most consistent black pigments available.

What is the history of carbon black as a pigment?

The history of pigments begins with carbon. Archaeological evidence of carbon black pigment used in cave art goes back over 30,000 years. Ancient Egyptians used soot-based inks for writing and cosmetics. Chinese ink stick production refined the carbon pigment into a form used for millennia in calligraphy. Industrial production in the 19th and 20th centuries scaled manufacturing enormously, and today carbon black is one of the most produced industrial materials globally.

What are the main uses of carbon black pigment today?

Carbon black pigment is used in printing inks, paints and coatings, plastics, toners, inkjet inks, cosmetics, and artists’ materials. Its largest single use is as a rubber reinforcing agent in tyre manufacturing, where it significantly increases durability and wear resistance.

Is carbon black pigment safe to use in art and cosmetics?

For artists’ paints and cosmetics, carbon black pigment in finished products is generally considered safe for the intended use. However, fine carbon black particles in powdered form are an inhalation risk and should not be breathed in. Artists working with dry pigment powders should use appropriate respiratory protection.

What is the difference between lamp black, ivory black, and Mars black in painting?

All three are black pigments used in painting but they differ in origin and character. Lamp black is a carbon black pigment made from soot, with a deep warm tone and slow oil-drying time. Ivory black is a carbon black pigment historically made from charred bone, with a slightly brown-warm undertone. Mars black is not a carbon pigment at all — it is a synthetic iron oxide that produces a cooler, more opaque black that dries faster, making it popular for underpainting.
