Vermilion
Artificial and natural pigmentComposition and Properties of Vermilion
Vermilion (cinnabar) is mercuric sulfide with the formula HgS. The oldest form of vermilion is finely ground mineral cinnabar. Mercuric sulfide can also be produced artificially.
The pigment is not affected even by strong concentrated acids and alkalis and is considered fairly lightfast but it can darken considerably. The darkening of vermilion has been studied extensively and is due to the transformation to the black form of HgS (1,2,3). It is compatible with other pigments.

Word origin
Vermilion
Late Latin vermiculus “a little worm,” specifically, the cochineal insect from which crimson dyes were obtained, in classical Latin, “larva of an insect, grub, maggot,” diminutive of vermis “worm”.

Cinnabar
“The word most likely comes from the ancient Greek κιννάβαρι kinnabari, later romanized to cinnabaris. In Persian, it is known as شنگرف shangarf; in the Arabic world it appears as زنجفرة zinjifrah.”

Preparation of Vermilion
The mineral has to be broken, ground and purified until the color is right.
Dry process
Mercury reacts readily with molten sulfur under the formation of the black form of mercury (II)-sulfide. This form can be transformed into the red form by sublimation.
Wet process
The German chemist Gottfried Schulz discovered that the black form can be transformed into the red form by heating it in a solution of ammonium or potassium sulfide (2). This being a much simpler and cheaper method than the sublimation in the dry process.

History of Use of Vermilion
Vermilion has been in use since antiquity until modern times. The following graph gives the frequency of its use from the 14th till the 19th century in the paintings of the Schack Collection in the Bavarian State Art Collections in Munich (1).
