Caput Mortuum
''Caput mortuum'' (plural ''capita mortua'') is a Latin term whose literal meaning is "dead head" or "worthless remains", used in alchemy. ''Caput mortuum'' (alternately called ''nigredo'') signified a useless substance left over from a chemical operation such as sublimation and the epitome of decline and decay; alchemists represented this residue with a stylized human skull, a literal death's head. The symbol shown on this page was also used in 18th-century chemistry to mean ''residue'', ''remainder'', or ''residuum''. ''Caput mortuum'' was also sometimes used to mean ''crocus metallorum'', i.e. brownish-red metallic compounds such as ''crocus martis'' (ferrous sulfate Iron(II) sulfate (British English: iron(II) sulphate) or ferrous sulfate denotes a range of salts with the formula Fe SO4·''x''H2O.

Alchemy
Alchemy (from Arabic: ''al-kīmiyā''; from Ancient Greek: χυμεία, ''khumeía'') is an ancient branch of natural philosophy, a philosophical and protoscientific tradition that was historically practiced in China, India, the Muslim world, and Europe. In its Western form, alchemy is first attested in a number of pseudepigraphical texts written in Greco-Roman Egypt during the first few centuries AD.Principe, Lawrence M. The secrets of alchemy'. University of Chicago Press, 2012, pp. 9–14. Alchemists attempted to purify, mature, and perfect certain materials. Common aims were chrysopoeia, the transmutation of "base metals" (e.g., lead) into "noble metals" (particularly gold); the creation of an elixir of immortality; and the creation of panaceas able to cure any disease. The perfection of the human body and soul was thought to result from the alchemical ''magnum opus'' ("Great Work"). The concept of creating the philosophers' stone was variously connected with all of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nigredo
In alchemy, nigredo, or blackness, means putrefaction or decomposition. Many alchemists believed that as a first step in the pathway to the philosopher's stone, all alchemical ingredients had to be cleansed and cooked extensively to a uniform black matter. In analytical psychology, the term became a metaphor for "the dark night of the soul, when an individual confronts the shadow within." Jung For Carl Jung, "the rediscovery of the principles of alchemy came to be an important part of my work as a pioneer of psychology". As a student of alchemy, he (and his followers) "compared the 'black work' of the alchemists (the nigredo) with the often highly critical involvement experienced by the ego, until it accepts the new equilibrium brought about by the creation of the self." Jungians interpreted nigredo in two main psychological senses. The first sense represented a subject's initial state of undifferentiated unawareness, "the first nigredo, that of the ''unio naturalis'', is an obje ...

Sublimation (chemistry)
Sublimation is the transition of a substance directly from the solid to the gas state, without passing through the liquid state. Sublimation is an endothermic process that occurs at temperatures and pressures below a substance's triple point in its phase diagram, which corresponds to the lowest pressure at which the substance can exist as a liquid. The reverse process of sublimation is deposition or desublimation, in which a substance passes directly from a gas to a solid phase. Sublimation has also been used as a generic term to describe a solid-to-gas transition (sublimation) followed by a gas-to-solid transition ( deposition). While vaporization from liquid to gas occurs as evaporation from the surface if it occurs below the boiling point of the liquid, and as boiling with formation of bubbles in the interior of the liquid if it occurs at the boiling point, there is no such distinction for the solid-to-gas transition which always occurs as sublimation from the surface.

Ferrous Sulfate
Iron(II) sulfate (British English: iron(II) sulphate) or ferrous sulfate denotes a range of salts with the formula Fe SO4·''x''H2O. These compounds exist most commonly as the hepta hydrate (''x'' = 7) but several values for x are known. The hydrated form is used medically to treat iron deficiency, and also for industrial applications. Known since ancient times as copperas and as green vitriol (vitriol is an archaic name for sulfate), the blue-green heptahydrate ( hydrate with 7 molecules of water) is the most common form of this material. All the iron(II) sulfates dissolve in water to give the same aquo complex e(H2O)6sup>2+, which has octahedral molecular geometry and is paramagnetic. The name copperas dates from times when the copper(II) sulfate was known as blue copperas, and perhaps in analogy, iron(II) and zinc sulfate were known respectively as green and white copperas. It is on the World Health Organization's List of Essential Medicines. In 2020, it was the 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Copper is a chemical element A chemical element is a species of atoms that have a given number of protons in their nuclei, including the pure substance consisting only of that species. Unlike chemical compounds, chemical elements cannot be broken down into simpler sub ... with the Symbol (chemistry), symbol Cu (from la, cuprum) and atomic number 29. It is a soft, malleable, and ductility, ductile metal with very high thermal conductivity, thermal and electrical conductivity.

Alchemical Substances
Alchemical studies produced a number of substances, which were later classified as particular chemical compounds or mixtures of compounds. Many of these terms were in common use into the 20th century. Metals and metalloids * Antimony/ – Sb * Bismuth (german: Wismuth) – Bi * Copper/ – associated with Venus. Cu * Gold/ – associated with the Sun. Au * Iron/ – associated with Mars. Fe * Lead/ – associated with Saturn. Pb * Quicksilver/ – associated with Mercury. Hg * Silver/ – associated with the Moon. Ag * Tin/ – associated with Jupiter. Sn Minerals, stones, and pigments * Bluestone – mineral form of copper(II) sulfate pentahydrate, also called blue vitriol. * Borax – sodium borate; was also used to refer to other related minerals. * Cadmia/Tuttia/Tutty – probably zinc carbonate. * Calamine – zinc carbonate. * Calomel/Horn Quicksilver/horn mercury – mercury(I) chloride, a very poisonous purgative formed by subliming a mixture of mercuric chlori ...
