ORPIMENT MINERAL SPECIMEN
A rare Orpiment Mineral Specimen formation. This one has a glowing vibrant orange colour. In days of yore this mineral was used for colour pigment. I can see just a hint of square Barite jutting out on top.
Palomo Mine, Andes, Peru.
7cm x 3cm x 2.5cm, 77g.
ORPIMENT As2S3, Arsenic Sulfide.
A major ore of arsenic, formerly used for pigments, firework colouring agent and as mineral specimens.
Orpiment is derived from the latin auripigmentum or golden pigment. Its use as a dye or pigment is limited due to its instability. Over time, orpiment will deteriorate into a powder. The process takes a long time and but exposure to light will accelerate it. Specimens should be stored in dark, enclosed containers.
Contains Arsenic, always wash hands after handling container. Like don’t touch it and don’t blow the dust off it as you don’t want to inhale the dust. This one is like the pretty looking spider…
