He also mentions the fact that clay (argilla) is used for iron welding, and further orpiment (auripigmentum), realgar
(sandaraca), minium (minium) from silver-mines (used as a pigment), ruddle or red ochre (rubrica, Greek miltos), cinnabar (cinnabaris) and Sinopian earth (sinopis) for painting, yellow ochre (sil) from gold- and silver-mines ("the best [.
For instance, the combination of Realgar
(tetraarsenic tetrasulfide), Indigo Naturalis, Radix Salviae Miltiorrhizae and Radix Pseudostellariae has been proved to be effective in the treatment of human acute promyelocytic leukemia (APL).
with Calcite Jiepaiyu Mine, Shimen, Hunan Prov.
The program met its objectives, successfully filling in the gaps in the resource model, extending and defining the near surface limits of previously known mineralization (as shown on the attached map) and resulting in the discovery of a new zone of mineralization, the Realgar
Zone, at the intersection of the Black and Central Zones.
You will recall that in late 2005 and into 2006 the market was briefly flush with superb specimens of realgar
from a then-new find in one of the old mines of Baia Sprie (formerly Felsobnsanya), Romania.
Within the intrusive and intrusive breccia, oxidation is less well developed and primary sulphides and realgar
are observed in a number of drill holes.
For instance, it is reported that the combination of Realgar
(tetraarsenic tetrasulfide), Indigo Naturalis, Radix Salviae Miltiorrhizae and Radix Pseudostellariae had exerted a synergic effect in treating human acute promyelocyte leukemia (APL) (Wang et al.
These include: (1) chemically reactive sedimentary carbonate rocks; (2) range front faults with accompanying heavy rock brecciation; (3) frontal fault jasperoids with stibnite and fluorite and high contents of arsenic, antimony and mercury; (4) overall hydrothermal mineral assemblage of stibnite, realgar
, cinnabar, fluorite, and barite; and (5) widespread presence of anomalous amounts of gold.
specimens are infamous for their photosensitivity, cracking apart and changing from a beautiful dark red color to orange and yellow if they are not kept strictly in the dark.
Jaroslav Hyrsl's article in March-April 2008 brought the small, inactive Palomo mine, in Huancavelica Department, to our attention, chiefly noting the very nice realgar
specimens found there in 2006.
Oh yes, Jaroslav also offered thumbnails showing blocky, bright red realgar
crystals to 1.
Since 2000 the Palomo mine has sparingly produced excellent and distinctive specimens of realgar
--the author of this article brought a fine lot of realgar
specimens to the 2007 Tucson Show.
