Cinnabar crystallized (2016) by Monte Amiata Volcanic ActivityMuseum of Mines of Mercury Monte Amiata

Cinnabar

Mercury sulfide, HgS, is the most important mineral for the extraction of mercury. Extracted from the deposit of the mine of Abbadia San Salvatore, the most important of the 'Amiata area, reaching up to 470 meters deep.

The Cinnabar is a mineral of hydrothermal genesis, which is the form that is a result of the cooling and consolidation of the fluids magmatic residues

Cinnabar strawberries (2015) by Monte Amiata Volcanic ActivityMuseum of Mines of Mercury Monte Amiata

In the case of strawberries is cinnabar combined with calcite crystals.

CINNABAR (2015)Museum of Mines of Mercury Monte Amiata

Cinnabar was already used at the time of the Roman Empire as a pigment and cosmetics, and for the extraction of mercury

Calcite is a mineral consisting of neutral calcium carbonate. It is the main constituent of limestone and marble.

Cinnabar (2015) by Monte Amiata Volcanic ActivityMuseum of Mines of Mercury Monte Amiata

The most important deposits are located at Almadén in Spain, in Italy in the Monte Amiata area and in Idrija in Slovenia.

Epsomite (2015) by Monte Amiata Volcanic ActivityMuseum of Mines of Mercury Monte Amiata

Minerals of Amiata

Epsomite or Epsom salt is magnesium sulfate, also known as bitter salt, owes its name to the mineral reserves discovered in the homonymous town in England, UK

FLUORITE (2014) by Associazione Minatori per il MuseoMuseum of Mines of Mercury Monte Amiata

The Fluorite, is a rather common mineral composed of calcium fluoride.
In nature the fluorite is usually found in hydrothermal veins and cavities of metamorphic and igneous rocks.

CHALK QUARTZ BARITE (2014) by Associazione Minatori per il MuseoMuseum of Mines of Mercury Monte Amiata

Gypsum is a sedimentary rock of chemical origin
Quartz is a common constituent of magmatic intrusive rocks
Barite is to deposit the form of hydrothermal solutions, especially at elevated temperatures

CALCITE (2014) by Associazione Minatori per il MuseoMuseum of Mines of Mercury Monte Amiata

Calcite of sedimentary origin, it may also originate in metamorphic and igneous rocks, where it is deposited in the fractures with circulating high-temperature fluid.

QUARTZ AND AMETHYST (2014) by Associazione Minatori per il MuseoMuseum of Mines of Mercury Monte Amiata

Quartz and Amethyst, this belongs to the family of crystalline quartz and owes its violet color in the presence of traces of iron. It is formed through hydrothermal process.

QUARTZ AND AMETHYST (2014) by Associazione Minatori per il MuseoMuseum of Mines of Mercury Monte Amiata

The Amethyst is one of the most popular stones in crystal. Greeks and Romans believed that it is an excellent remedy against the effects of alcohol.

Stibnite and Cinnabar (2015) by volcanic activity of Mount AmiataMuseum of Mines of Mercury Monte Amiata

The stibnite, or antimony sulfide is mostly of hydrothermal origin.
It has an important role in many metal alloys, in electric batteries, in the healthcare industry, textile, rubber and glas.

Mercury (2016)Museum of Mines of Mercury Monte Amiata

Mercury

The specific weight of mercury is fourteen times greater than that of water. Lead floats on mercury.

Mercury cylinders (1916)Museum of Mines of Mercury Monte Amiata

The iron bomboles which contained mercury were cylindrical in shape with a capacity of 2,7 L, threaded closure cap screwing and weighed 34,5 Kg of mercury, standard weight established for the trade.

Davide Franceschelli explains what it is, from what we get and what are the uses of mercury.

Realgar (2016)Museum of Mines of Mercury Monte Amiata

Realgar is a mineral, arsenic sulfide, ruby red mass and orange yellow powder. It is formed in volcanic exhalations and hydrothermal mineralization.

Celestite (2016)Museum of Mines of Mercury Monte Amiata

The celestite is a mineral consisting of strontium sulphate. It is located in the limestone and sedimentary soils, but can also have hydrothermal origin

Orthoclase (2016)Museum of Mines of Mercury Monte Amiata

The orthoclase of the alkali feldspar group is the name of an important group of minerals that probably make up 60% of the earth's crust.

Marcasite (2016)Museum of Mines of Mercury Monte Amiata

The Marcasite is an iron sulfide with golden metallic color. It is found as a primary mineral in sedimentary rocks and in hydrothermal veins of low temperature.

Dawnsonite (2016)Museum of Mines of Mercury Monte Amiata

Dawnsonite comes in the form of deposits or in masses of minutes laminar crystals, white, radial.
It has its origin in hydrothermal veins of low temperature, generally in the veins of cinnabar.

Diatomite (2016)Museum of Mines of Mercury Monte Amiata

Diatomaceous earth, or diatomite, is a biogenic siliceous sedimentary rock. It is the fossil remnant of microscopic algae diatom family.
