What is orpiment? Origin and etymology

Orpiment is a vibrant, powerful golden color. Its name comes from the naturally occurring mineral called "orpiment." In English, it is called orpiment, and chemically it is an arsenic compound called diarsenic trisulfide (As2S3).

This mineral is often found together with a reddish-orange mineral called "realgar." It is said that the name "realgar" (女黄) comes from the ancient Chinese concept of yin and yang, where the lighter color was seen as "female" and the darker color as "male." As the name suggests, it is characterized by a color that possesses both softness and elegance.

While oryzae possesses a beautiful color, it is also highly toxic due to its arsenic content. This duality has given oryzae a mysterious and somewhat dangerous allure. In addition to being used as a pigment, it was also used in the past as a medicine and insect repellent, but its handling required extreme caution.

Historical background of orpiment

The use of orpiment is ancient, and it was already known as a pigment during the Han Dynasty. Its golden luster made it a highly valued color, symbolizing noble beings such as emperors and gods.

In Taoism in particular, orpiment, along with realpiment, was considered an ingredient in the "golden elixir," a miraculous elixir of immortality. However, it is actually a highly toxic arsenic compound, and it is said that this led to tragedies in which many people who dreamed of becoming immortals instead lost their lives.

Furthermore, orpiment was also used as an "eraser" to correct writing. Some ancient papers were colored yellow, and by applying orpiment powder to areas where writing mistakes had been made, the writing could be made invisible.

This custom gave rise to the idiom "shinkō shikou," which refers to the attitude of carelessly correcting statements or making arbitrary criticisms without any basis, just as one would easily rewrite words with yellow ink. It is an interesting example of how a color itself became a lesson about the weight of words.

Oryct in Chinese Art and Crafts

The vibrant yellow of orpiment played a crucial role in Chinese art, particularly Buddhist art. In the murals of the Dunhuang Mogao Caves, orpiment was lavishly used as a substitute for gold to depict the halos and robes of Buddha statues, as well as the sacred spaces within them. In the dimly lit caves, the glow of the orpiment must have appeared to people like a divine aura.

In ink painting and brushwork, it was used to add vibrancy and accent to works, such as depicting autumn foliage or the clothing of noble figures. However, because it contains sulfur, it easily reacts chemically with other pigments and discolors, making it a difficult pigment for painters to work with.

In clothing culture, oryzae was primarily used as a pigment to draw patterns on fabrics rather than as a dye. Mineral pigments do not easily penetrate fibers, making them unsuitable for dyeing entire pieces of cloth. However, it is believed that oryzae patterns drawn on silk fabrics and other materials made the garments appear even more luxurious due to their brilliance.
