Artist\\\\\\\'s dry pigment Orpiment (\\\\\\\"King\\\\\\\'s Yellow\\\\\\\"):
Natural Orpiment Pigment fine grane is suitable for use in paints,tempera, lacquers, and inks. It is a highly toxic. It should not be used for cosmetic purposes.
Origin and History:
Orpiment is a stone, found throughout the world as a low-temperature product of hydrothermal veins, hot-spring deposits, and volcanic sublimation. In its natural state, it has a mica-like sparkle which recalls the luster of metallic gold. An ancient pigment, used throughout the Middle East and Asia through the late 19th century. During the Renaissance, orpiment was imported to Venice from Asia Minor.
Making the Pigment: Mineral orpiment is heated with sulfur, allowing a more pure orpiment to sublime out. Orpiment is particularly difficult to grind into a pigment. An artificial variety of pigment is made by fusing of arsenic or arsenic oxide with sulfur.
Chemical Properties: Yellow Arsenic Tri-sulfide, As2S3. Monoclinic, transparent to opaque. In close proximity, orpiment can react with lead colors such as flake white and minium (\\\\\\\"red lead,\\\\\\\" an orange color). It outgases, meaning that orpiment vapors will creep over to the lead colors and corrupt them, reverting them to a lead-gray color. This process can creep a couple of inches in as many months, or less. It cannot be used to modify green tones containing verdigris, as the sulphur of the orpiment attacks copper in the same way. It also has a corrosive action on binding materials, and has quite often decayed and come away from panels and parchment.
Artistic Notes: Its color is light, vivid yellow in color, sometimes pure yellow but often inclined toward orange. When mixed with zinc or titanium white, it loses its yellow tones becoming a pale brown/beige.
