Newer research indicates that chlorine ions and light may aid in decomposing vermilion into elemental mercury, which is black when in finely dispersed form. Vermilion has one important defect it is liable to darken, or develop a purplish-gray surface sheen. The pigment is still made today using essentially the same process. To remove the sulfur, these crystals were treated with a strong alkali, washed, and finally ground under water to yield the commercial powder form of the pigment. Mercury and melted sulfur were mashed to make black mercury sulfide, then heated in a retort, producing vapors condensing as a bright, red mercury sulfide. In the 17th century, a new method of making the pigment was introduced, known as the Dutch method. Italian Renaissance artist Cennino Cennini wrote: "If you were to grind it every day, even for 20 years, it would keep getting better and more perfect." The longer the compound is ground, the finer the color becomes. When first created, the material is almost black. Heat this in a flask (the compound vaporizes and recondenses in the top of the flask).Mix mercury with sulfur to form aethiopes mineralis, a black compound of mercury sulfide.The process described by Jabir ibn Hayyan was fairly simple: In the early 9th century, the process was accurately described by Persian alchemist Jabir ibn Hayyan (722–804) in his book of recipes of colors, and the process began to be widely used in Europe. Greek alchemist Zosimus of Panopolis (third–fourth century AD) wrote that such a method existed. The Chinese were probably the first to make a synthetic vermilion as early as the fourth century BC. Efforts began early to find a better way to make the pigment. Greek philosopher Theophrastus of Eresus (371–286 BC) described the process in De Lapidibus, the first scientific book on minerals. Larger crystals produce duller and less-orange hues.Ĭinnabar pigment was a side product of the mining of mercury, and mining cinnabar was difficult, expensive, and dangerous, because of the toxicity of mercury. Differences in hue are caused by the size of the ground particles of pigment. Vermilion is not one specific hue mercuric sulfides make a range of warm hues, from bright orange-red to a duller reddish-purple that resembles fresh duck liver. Like most mercury compounds, it is toxic. The pigment was originally made by grinding a powder of cinnabar ( mercury sulfide). Vermilion is a dense, opaque pigment with a clear, brilliant hue. Thus, the natural mineral pigment is called "cinnabar", and its synthetic form is called "vermilion" from red lead. The term cinnabar is used in mineralogy and crystallography for the red crystalline form of mercury sulfide HgS. The first recorded use of "vermilion" as a color name in English was in 1289. The name originated because it had a similar color to the natural red dye made from an insect, Kermes vermilio, which was widely used in Europe. Used first in English in the 13th century, the word vermilion came from the Old French word vermeillon, which was derived from vermeil, from the Latin vermiculus – the diminutive of the Latin word vermis for worm. It is synonymous with red orange, which often takes a modern form, but is 11% brighter (at full brightness). Vermilion (sometimes vermillion) is a color family and pigment most often used between antiquity and the 19th century from the powdered mineral cinnabar (a form of mercury sulfide).
