The Greek for orpiment was arsenikon, deriving from the Greek word arsenikos, meaning "male", from the belief that metals were of different sexes. This Greek term was used by Theophrastus in the fourth century BC. [5] The Chinese term for orpiment is Ci-Huang (in Pinyin), meaning "female yellow". [6]
Arsenic blende or Arsenblende (German: Arsenblende, arsenik-blende) is a trivial name that has partially fallen out of scientific use, used by mineralogists, as well as representatives of mining and craft professions in relation to at least two similar ore minerals — orpiment and realgar, [1]: 135, 239, 438 in composition — arsenic sulfides.
Both orpiment and realgar, as well as As 4 S 3, have selenium analogs; the analogous As 2 Te 3 is known as the mineral kalgoorlieite, [39] and the anion As 2 Te − is known as a ligand in cobalt complexes. [40] All trihalides of arsenic(III) are well known except the astatide, which is unknown.
This is a list of Latin words with derivatives in English (and other modern languages).. Ancient orthography did not distinguish between i and j or between u and v. [1] Many modern works distinguish u from v but not i from j.
Arsenic trisulfide is the inorganic compound with the formula As 2 S 3.It is a dark yellow solid that is insoluble in water. It also occurs as the mineral orpiment (Latin: auripigmentum), which has been used as a pigment called King's yellow.
One of the "Five Ks" of Sikhism is Kesh, meaning "hair". [32] Baptized Sikhs are specifically instructed to have unshorn Kesh (the hair on their head and beards for men) as a major tenet of the Sikh faith. To Sikhs, the maintenance and management of long hair is a manifestation of one's piety. [32]
When arsenopyrite is heated, it produces sulfur and arsenic vapor. With 46% arsenic content, arsenopyrite, along with orpiment, is a principal ore of arsenic. When deposits of arsenopyrite become exposed to the atmosphere, the mineral slowly converts into iron arsenates.
The colour was also used later by medieval artists for the colouring of manuscripts. Pigments were also made in ancient times from a mineral known as orpiment. Orpiment was an important item of trade in the Roman Empire and was used as a medicine in ancient China although it contains arsenic and is highly toxic. It was also used as a fly poison ...
