Orpiment – Due to the softness of orpiment, the preparation of an elixir via the normal method is not recommended" (Love is in the Earth - Updated 464). Do not use this mineral in any elixir. "An arsenic." (Jentoft) Do not use this mineral in any elixir.

Orpiment and Realgar are both arsenic sulfides. Orpiment is a rare orange to lemon-yellow mineral consisting of a native trisulfide of arsenic and usually forms with Realgar. Realgar and Orpiment are almost always found together. Realgar is a bright reddish-orange

These fantastic getchellite, orpiment and stibnite combo specimens come from the collection of a former Senior Mine Geologist at Getchell.Between 1988 and 1989 in the South Pit of this famous gold mine, collecting was done in a series of unique, highly-mineralized getchellite zones, right when it was best exposed in the pit wall during commercial mining.

ORPIMENT is used to stimulate the intellect and is very useful in cleansing and activating the solar plexus chakra. It assists us in our capability for reasoning. It brings growth to that which is impaired, assisting us in recognizing that which is conceivable and helps us to promote necessary action.

PRELIMINARY CONSIDERATIONS In the 1950s it was thought that although the structure of orpiment (As 2 S 3), is a common monoclinic crystal system of an arsenic sulfide mineral (P2 1 /c, a=4.256 ; b= 9.577 ; c=12.19 and β=109.75 ), it seemed to have little similarity with the orange-red arsenic sulfide mineral realgar (α-As 4 S 4) 12-14.

Orpiment

Orpiment is a deep-colored, orange-yellow arsenic sulfide mineral with formula As 2 S 3.It is found in volcanic fumaroles, low-temperature hydrothermal veins, and hot springs and is formed both by sublimation and as a byproduct of the decay of another arsenic mineral, realgar..

Rock of the Month # 99, posted for September 2009--- Galena (PbS) is the principal ore mineral of lead, while orpiment is one of the more readily identified arsenic-rich sulphides. The Quiruvilca district, located in a Miocene metallogenic belt in northern Peru, has been mined for polymetallic veins of copper, lead, zinc, silver and gold (Hollister, 1977; Hermelin, 1986; Bartos, 1989, 1990

Haritalam (Orpiment) : Haritalam, properly purified, cures phlegm, vataraktam, poison, excess of air, and fear from ghosts. It stops menstrual discharge, is soothing, pungent, and produces a warm effect on the system. It increases the appetite and cures

s) : Orpiment is of a Colour Closest to Gold In his Il Libro dell'arte, Cennino Cennini writes that orpiment is made by alchemy. It is true that by the early Renaissance most of the pigments artists were using were manufactured, but orpiment is actually a naturally occurring mineral: a canary-yellow sulphide of arsenic that is around sixty percent arsenic.

Orpiment was probably not mined in ancient Egypt, though it was used there. Possibly it was imported from Persia.10 It was brought into the classical Mediterranean world from Syria, Cap-padocia,12 Mysia (Hellespont),13 Pontus,14 and Carmania (Kirman).5

Late stage realgar and orpiment are commonly associated with high-grade ores. The main deposit is confined to a zone nearly 7000 ft. long at the northern end of the Getchell fault zone. Deep exploration shows that the mineralization persists at least 1 km down-dip on the Getchell fault system and also occurs along the parallel Village fault.

Orpiment, on the other hand, is composed of two arsenic atoms and three sulfur atoms. Neither species is particularly stable over time. Intense sunlight can cause realgar to slowly convert to a more stable form called pararealgar, an orange-yellow mineral that is often seen as a coating or dusting on the realgar.

2013/3/7Orpiment is known to give off a strong garlic smell due to its arsenic content, and may crumble into dangerous powder when exposed to light. The mineral was used as a primary component of ochre paint, and likely poisoned many of the artists who used it.

This list includes those recognised minerals beginning with the letter O.The International Mineralogical Association is the international group that recognises new minerals and new mineral names, however minerals discovered before 1959 did not go through the official naming procedure, although some minerals published previously have been either confirmed or discredited since that date.

This highly polished specimen was mined in the central asian nation of Kyrgyzstan, and was purchased several years ago at the Tuscon show. Similar Orpiment sps are currently listed on eBay and other internet sites for $300 to $600. The brass display stand is
