Stone crimson quartzite is a rock. In other words, it consists of several minerals, the main one being quartz. From him, in fact, the name came from. Small amounts of topaz, corundum, sericite, pyrophyllite, feldspar, and talc are mixed with quartz. During the recrystallization of sandstones, this mixture is formed. This metamorphosis occurs under the influence of temperature or pressure.
Description
Raspberry quartzite, reviews of which are listed in the article below, occupies a separate place among the huge number of types of Karelian minerals. By its properties it is a unique stone. It is also called porphyry, or Shokhan porphyry (due to its resemblance to Iranian porphyries). It means "royal stone".
Mineral combines very high strength, wear resistance, hardness, as well as a beautiful appearance.
Crimson Quartzite, as demonstrated by medical studies,has medicinal properties. So, it stabilizes blood pressure, eliminates ailments in weather-sensitive people that were caused by weather changes, and also relieves pain in the joints and lower back.
In the bath, the Shoksha raspberry quartzite makes the steam very light. This effect is achieved due to the low thermal conductivity and high density of the stone, which together gives excellent heat dissipation over time.
Historically, this mineral was intended to decorate various majestic structures and buildings in St. Petersburg and Moscow. Perhaps this is the most solemn nugget from the Onega region.
Shoksha raspberry quartzite has always been highly valued, which means it was used for decoration of especially significant architectural projects. According to its mineral composition, it is considered almost pure quartz (about 98%). It is an environmentally friendly material, almost does not have radioactivity, and this makes it possible to use it for facing offices and residential premises. Good resistance to high temperatures gives advantages when using the mineral in sauna and bath ovens.
Chemical properties
Quartzite is obtained from sandstones, consisting of large fragments of sedimentary origin bonded with natural cement. Some large sandstone fragments are preserved during recrystallization. Consequently, quartzites often have an uneven structure. In the mineral, crystals of mica and quartz are clearly visible. Bonding such particles of various sizes makes the stone very strong.
The strength characteristic is directly related to the composition of the stone, since quartz (its main component) on the Mohs scale has a hardness index of 7 points. At the same time, topazes, which are also included in quartzites, occupy the eighth line in the scale. The corundums mixed with the rock are inferior only by a point to diamonds, the champions of hardness, whose indicator is 10 points. In total, the hardness of quartzite adds up to about 8 points.
In addition to high strength, crimson quartzite, the properties of which are described in this article, is resistant to temperature. Its negative values do not affect the stone. Fire resistance is also impressive. The mineral begins to change only at 1770 ˚С. Such resistance to heat makes the stone an excellent raw material for the construction of steam rooms. Raspberry quartzite for a bath, reviews of which are always positive, makes it durable and safe. With active exploitation, the life of the rock is about 200 years.
Stone is uneasy and high humidity. The mineral is not affected by various chemical reagents. At the same time, the rock does not react with acids and alkalis. But raspberry quartzite is not in a hurry to succumb to a person either. Due to the increased hardness, it is very difficult to process, which significantly increases the price of products from this breed. They tend to buy it for special occasions. For example, Napoleon's sarcophagus was made from this stone.
Deposits
This is a common stone. Among the metamorphic rocks, it occurs in extended, large layers. These depositsavailable in America, Africa, Russia and Eastern Europe. Thirty deposits have been registered on the territory of our country. Their main concentration is in the Urals.
Crimson Quartzite
Raspberry-colored minerals are suitable for accumulating heat in the ovens of baths and saunas. Their heat warms the air, ceiling, shelves and walls. Due to the high temperature of the minerals, when water is poured on them, a dense, moist steam is formed, warming the bathers.
Material
Mineral is a natural natural stone. It is characterized by a quartz homogeneous composition. Often mined in Karelia. It was used to decorate significant architectural buildings (in St. Petersburg it was used when decorating St. Isaac's Cathedral, or rather, its altar, the Kazan Cathedral, the Winter Palace). This environmentally friendly and beautiful material with excellent physical and mechanical properties can be used for stoves in baths and saunas.
Distinctive features of the mineral:
- has a low water absorption rate;
- high strength;
- durable;
- has low abrasion.
Application
Raspberry quartzite for a bath before being placed in a wood-burning or electric stove must be washed with water from dust, dried, and damaged and small stones must be thrown away. When laying in the oven, there should be a small space between the minerals for free air circulation. At the same time, flat, largest stones must be placed in the lower part, and small ones in the upper part.
The distance between the heating elements in electric furnaces should remain unchanged when laying stones. At the same time, the heating elements of the electric heaters must be covered with minerals (the ideal distance is about 5 centimeters above the heating elements).
Healing properties
According to various medical studies, raspberry quartzite has various healing properties:
- eliminates ailments from changing weather;
- equalizes pressure;
- helps with pain;
- strengthens male potency;
- improves blood composition.
The mineral is also credited with magical properties. It should be noted that for many it remains a mystery that has not yet been solved.
Stone in history
This is an amazing stone, which, by a lucky coincidence, has become a symbol of we alth and luxury. By decree of the tsar, it was prescribed to be used in the nineteenth century exclusively for significant construction projects, therefore, as mentioned above, it can be seen in the decoration of the facades and walls of the Winter Palace, the Kazan and St. Isaac's Cathedrals, the Mikhailovsky Palace and the Moscow Kremlin.
In addition, it was used to create the tomb of Napoleon. The lid and base of the sarcophagus were carved from solid pieces of crimson quartzite. It was a gift from Nicholas I. The delivery of these minerals from Karelia to the Russian treasury cost a lot of money. But it should be noted that the monument to Nicholas I was also made of crimson quartzite.
On thisstone prices are still very high - from 10,000 rubles per ton.
Radioactivity
It should be noted that, according to the results of gamma spectroscopy studies, the effective specific activity of natural radionuclides in quartzite reaches 194 Bq/kg. This does not exceed the acceptable value for building materials of the first class.
These minerals are used for the production of dinas, as well as in metallurgy as a flux, as an acid-resistant material, as well as a decorative and building stone.
Raspberry quartzite for a bath: reviews
Reading the reviews about this mineral, we can conclude that it is chosen by those who often do not want to buy stones for a bath and are looking for a "durable" option. This stone is able to survive its "brothers" in the bath of all types. Interestingly, pink quartzite is liked by people who take care of their he alth and appreciate the bath for its healing properties - according to many, the stone normalizes blood pressure, improves blood composition and circulation, eliminates back pain and muscle pain.
It is purchased by those who are very sensitive to changes in the weather, because, as they say, it makes it possible to get rid of this ailment. Of course, there are also negative reviews. However, for the most part, they come down to the very high cost of the stone. Not all bath owners can afford it.
