Artificial vermilion is a bright red pigment based on mercury sulfide (HgS), developed as a synthetic alternative to the rare natural mineral cinnabar. Its manufacture is already documented in antiquity, with early recipes described in Roman and later medieval technical sources, where mercury and sulfur were combined through controlled heating and grinding. Compared to natural cinnabar, artificial vermilion offered greater availability, more uniform color, and lower cost, which contributed to its widespread adoption in painting and manuscript illumination from the Middle Ages onward. The pigment is characterized by a strong, opaque red with high covering power, making it ideal for details, drapery, and symbolic elements. However, vermilion is also known for its chemical instability: under certain environmental conditions, particularly light exposure and the presence of chlorides, it may darken or alter in tone.
