Cinnabar, a dense red mineral, is the principal ore of the metal mercury, usually described as an intense reddish orange (See Cinnabar, Warm) or sometimes as a dark reddish purple. Our cold cinnabar is prepared from the mineral in ore deposits in Haydarkan, Kyrgyzstan. It has a masstone color of soft purplish red. History of Use: It is an historical pigment, but surprisingly not found in ancient Egyptian or early Mesopotamian objects. It was well known to the Romans and widely used in China since the third millennium B.C. Permanence and Compatibility: Authorities today do not consider cinnabar to be a permanent pigment. However, samples have been known to withstand exposure to sunlight for at least ten years. It is remarkably unreactive with other pigments despite that fact it is a sulfide. In oil-medium, it was commonly used with lead white to produce flesh tints with no sign of formation of black lead sulfide. It was used on alkaline lime fresco walls. The traditional use of red glazes of madder, kermes and cochineal lakes over cinnabar underpaint not only increases the purity (chroma) of the color, but has been shown to reduce its tendency to darken. The natural mineral is said to be more stable than manufactured vermilion. Oil Absorption and Grinding: Cinnabar absorbs a low amount of linseed oil when grinding the pigment in this medium. Linseed oil is very slow drying with cinnabar, yet it produces a strong paint film. Although considered by some to be an erratic pigment, cadmium reds do not replace its special hue or physical characteristics. Toxicity: Some authorities consider natural cinnabar to be non-toxic. Anita Albus writes that the deadly poison of mercury becomes harmless when it is stably bound with sulfur. However, we consider cinnabar to be toxic and urge caution in handling the dry powder pigment, as well as the pigment dispersed in medium.
