This beautiful new species is a new sulfosalt from the Zarshouran Au-As deposit, Iran, published in late 2009. Only a small number of these pieces were recovered and then studied. This is one of the largest extant specimens and is co-type material, which I obtained by exchange from the collection of Dr. Werner Paar of the University of Salzburg. Dr. Paar is lead author on the publication of the species (Mineralogical Magazine, Oct. 2009, vol. 73 #5.) Daliranite occurs as very rich orange-red crystals, eye visible but sub-mm in size, easily seen on this contrasting matrix specimen of quartz. It is associated with orpiment and other related species (he has identified both galkhaite and cinnabar as present on this piece). This specimen is a large, display-worthy piece that could EASILY be trimmed into 2 very fine but smaller display-quality samples, and perhaps yielding lesser reference specimens as well. The orpiment veins and crystals make this an attractive piece, overall. These specimens were found in 1998-2002 and studied only later, in Germany. Return trips by the authors in 2005 , to the dumps, were unsuccessful at finding more daliranite and it remains today a fairly rare species, thus. Originally, and erroneously, reported as ludlockite from Zarehehuran, Takap, Takht-e-Suleiman massif, Azerbaijan. Apparently, it was rather difficult to analyse and presented a fair challenge to the crystallographers. TYPE AND ONLY LOCALITY MATERIAL.

This beautiful new species is a new sulfosalt from the Zarshouran Au-As deposit, Iran, published in late 2009. Only a small number of these pieces were recovered and then studied. This is one of the largest extant specimens and is co-type material, which I obtained by exchange from the collection of Dr. Werner Paar of the University of Salzburg. Dr. Paar is lead author on the publication of the species (Mineralogical Magazine, Oct. 2009, vol. 73 #5.) Daliranite occurs as very rich orange-red crystals, eye visible but sub-mm in size, easily seen on this contrasting matrix specimen of quartz. It is associated with orpiment and other related species (he has identified both galkhaite and cinnabar as present on this piece). This specimen is a large, display-worthy piece. The orpiment veins and crystals make this an attractive piece, overall. These specimens were found in 1998-2002 and studied only later, in Germany. Return trips by the authors in 2005, to the dumps, were unsuccessful at finding more daliranite and it remains today a fairly rare species, thus. Originally, and erroneously, reported as ludlockite from Zarehehuran, Takap, Takht-e-Suleiman massif, Azerbaijan. Apparently, it was rather difficult to analyze and presented a fair challenge to the crystallographers. Type and only locality material.

Note it can be trimmed into two equally nice miniatures... 7 x 2.7 x 2.2 cm\u003C\u002Fdd>\u003C\u002Fdl>\u003C\u002Fdd>\u003C\u002Fdl>",372,{"id":613,"source_url":614,"license_code":296,"credit_html":615,"title":616,"description":617,"author":323,"original_width":340,"original_height":618},59808,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=10149163","Robert M.

At its simplest, a mineral is a naturally-occurring solid chemical.  Currently, there are over 4900 named and described minerals - about 200 of them are common and about 20 of them are very common.  Mineral classification is based on anion chemistry.  Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates.\n\u003C\u002Fp>\u003Cp>The sulfide minerals contain one or more sulfide anions (S-2).  The sulfides are usually considered together with the arsenide minerals, the sulfarsenide minerals, and the telluride minerals.  Many sulfides are economically significant, as they occur commonly in ores.  The metals that combine with S-2 are mainly Fe, Cu, Ni, Ag, etc.  Most sulfides have a metallic luster, are moderately soft, and are noticeably heavy for their size.  These minerals will not form in the presence of free oxygen.  Under an oxygen-rich atmosphere, sulfide minerals tend to chemically weather to various oxide and hydroxide minerals.\n\u003C\u002Fp>\u003Cp>Realgar and orpiment are both arsenic sulfides.  Realgar is an intensely reddish-orangish arsenic sulfide (AsS), while orpiment is a bright yellow-colored arsenic sulfide (As2S3).  They are always associated with each other.  Arsenic is a rare element in Earth’s crust, but because As has very few uses in modern society, it has practically no value.  Orpiment & realgar have a nonmetallic luster and are fairly soft (H=1 for yellow orpiment & H=2 for reddish-orange realgar).  The two minerals are fairly insoluble, but they do volatilize readily.

The Latin term was used by Pliny the Elder in the first century CE[2]. An older Greek name, *arsenikon*, came from a root meaning \"male\", drawing on ancient ideas about the sexes of metals; Theophrastus used it in the fourth century BC[3]. The Persian *zarnikh* and the Chinese *Ci-Huang* — \"female yellow\", set against realgar's \"male yellow\" — likewise pointed at the colour gold[3].\n\nLong before either name reached Europe, the substance itself was already a paint. Egyptian artisans used orpiment in tomb decoration as early as the fourteenth century BC; it appears among the wall decorations of Tutankhamun's tomb and on ancient Egyptian scrolls[4]. Central Asian painters used it on wall paintings between the sixth and thirteenth centuries[4]. Chinese lacquerware took it up early too, and ground orpiment served in ancient China as a correction fluid for ink errors on bamboo and paper[5].\n\nIn the eastern Mediterranean the mineral travelled as both pigment and poison. Orthodox icon painters in Bulgaria, Russia, and the territories of former Yugoslavia worked with it between the twelfth and sixteenth centuries[4]. Alchemists in China and in Europe, captivated by its gold-like sheen, pursued it in their long search for a way to make gold[6]. They also drew on it as a source of elemental arsenic — the bright yellow ore was, for centuries, the most accessible window onto that element.\n\nEuropean medieval and Renaissance painters used orpiment as the truest yellow available before modern chrome and cadmium pigments. Combined with indigo dye it produced a deep rich green visible in works such as the *Wilton Diptych* of about 1395 to 1399[7]. Raphael deployed it in the *Sistine Madonna* of 1513 to 1514, where the pigment colours the clothing of the figures and the background; Tintoretto used it in his *Portrait of Vincenzo Morosini* of about 1575 to 1580 to replicate the gold embroidery and other details[8]. In the seventeenth century Robert Hooke mentioned the mineral in his *Micrographia* for the manufacture of small shot[9].\n\nA refined eighteenth-century version called **king's yellow** kept the pigment in artists' studios until safer alternatives arrived[10]. Production of artificial arsenic trisulfide began in the same century to feed western demand, which had been comparatively muted until then[10]. Two problems then closed the trade: the mineral's extreme toxicity, and its incompatibility with other common pigments — particularly lead and copper compounds such as verdigris and azurite, which it darkens on contact[11]. Cadmium yellows, chromium yellows, and aniline dyes replaced it in the nineteenth century[11].","claude-opus-4-7","1.7.0",{"markdown":1037,"model_version":1034,"prompt_version":1035,"reviewed_at":11},"The brightest modern life of orpiment is hidden inside infrared optics. Arsenic trisulfide — synthetic As₂S₃, the same compound as the natural mineral — is one of the workhorse chalcogenide glasses, a family of glasses made from sulfur, selenium, or tellurium that transmit infrared light where ordinary silica glass does not[1]. The material is drawn into infrared-transmitting glass for lenses and windows, and is used as a semiconductor and photoconductor[1].\n\nIndustrial uses outside optics are scattered and thin. The same compound appears in oil cloth, linoleum, and pyrotechnic mixtures, and lingers in a few restoration pigments[1]. In rural India a paste of orpiment mixed with slaked lime is used as a depilatory, and the tanning industry employs the same chemistry to remove hair from hides[2]. None of these uses sustains a significant arsenic-mining trade in their own right.\n\nBeyond these niches the modern role is largely geological. Well-formed yellow crystals are sought by collectors and museums as representatives of the species, and the mineral remains a minor historical source of arsenic. Its toxicity continues to surface in unexpected places — a 2023 British recall of orpiment bookends sold by a high-street retailer prompted public-health warnings about ornamental arsenic minerals in the home[3]."]
