Spotlight on Vermilion

How to create Vermilion
The brilliant and distinctive red of vermilion has been used extensively across thousands of years of art history, from the art and decoration of Ancient China and Rome through to the manuscripts of the middle ages and the paintings of the Renaissance.

A Beautiful But Dangerous Colour

Naturally occurring vermilion is an opaque orangish red pigment and was originally derived from powdered mineral cinnabar, the ore of which contains mercury making it toxic. Infact in ancient times many of the miners who extracted the ore paid a high price with their lives due to the toxicity of the substance. The word vermilion is derived from the French vermeil meaning any red dye which in turn comes from vermiculum, a red dye made from the insect Kermes vermilio.  

Ancient China Takes The Initiative

China has been credited with first synthesizing vermilion from mercury and sulphur. The earliest known description of this process dates from the 8th century China. ‘China Red,’ as it became known, was an everyday part of Chinese life from palatial red lacquers to the printing-pastes for personal name stamps to the red calligraphic ink reserved for Emperors.

Vermilion: The Colour Of Victory

Vermilion was equally revered by the Romans who painted the faces of their triumphant generals with it. The vermilion coated faces were to match the vermilion visage of the image of Jupiter Capitolinus in the temple on the Capitoline Hill. Because pure cinnabar was so rare, vermilion became immensely expensive and the price had to be fixed by the Roman government at 70 sesterces per pound - ten times the price of red ochre.

Buyer Beware

The story of a highly expensive highly sought after colour continued into the 12th century where synthetically produced vermilion was used throughout Europe. Costing as much as gilding, it was used mostly to illuminate manuscripts and vermilion still featured as a colour in illuminating kits available from the early to mid 19th century.

During the 14th century, the technique for synthesising vermilion became more widespread in Europe. Due to the repeatability and control over the process, synthetic vermilion was regarded early on as superior to the vermilion pigment derived from natural cinnabar. The Florentine artist Cennino Cennini in his book “Il libro dell’Arte” had some sound do-it-yourself advice for vermilion customers :

‘Always buy vermilion unbroken, and not pounded or ground. The reason? Because it is generally adulterated, either with red lead or with pounded brick.’(1)

The Dutch Take Control

From the 17th century, the Dutch method of manufacturing vermilion was used. Mercury and melted sulphur were mashed resulting in black mercury sulphide which was then heated in a retort giving off vapour. When this vapour condensed it gave a bright red crystalline form of the mercury sulphide and the crystallised mercury sulphide was then scraped off and treated with a strong alkali solution to remove the sulphur. The final pigment was produced after washing and grinding under water.

The Dutch looked back across the centuries basing their techniques on those adopted in ancient China. The names cinnabar and vermilion were used freely to describe either the natural or synthesised pigment until the 17th century, at which point vermilion became the more common name. By the late 18th century the name cinnabar was generally applied only to the unground natural mineral.

Pure And Not So Pure

By the mid 19th century Chinese vermilion was considered the purest form especially when compared to the European variety of the time. Due to the high cost of cinnabar, European vermilion was often cut with cheaper materials such as brick dust, orpiment, iron oxide, Persian red, iodine scarlet, and red lead. This debasement of the cinnabar would often make the final pigment unstable in artists’ colours.

Winds Of Change

Interest by the art world in vermilion declined during the 20th century owing to its cost and toxicity and cadmium red became a popular replacement which had comparable colour and opacity. Cadmium red and cadmium red deep are available in the Winsor & Newton Artists’ Oil Colour range.
 
Today vermilion is still most commonly synthesised by reacting mercury with molten sulphur and any naturally produced vermilion is most likely to come from cinnabar mined in China.

Culturally it still has immense significance. In Indian, Hindu women use vermilion along the hair parting line, known as Sindoor, to signify that they are married. Hindu men often wear the vermilion on their forehead during religious ceremonies. Vermilion also has significance in Taoist culture, regarded as the color of life and eternity.
