Development History of the Stone in the World

The mining, processing, trade of natural stone is part of the oldest activities, throughout the history of human civilization.

During the Roman Empire, and the Romans are the Eastern Mediterranean’s dominant, monopoly local marble mining, mine is the emperor of all.

After the fall of the Roman Empire, from the 5th century to the 12th century is the decline of the mining of marble and other stones. 15, ad, many countries producing their stone and imported stones and they have needs, stone mining thrived again.

Subsequently, the industrial revolution in Europe, is a groundbreaking development and mining of stone.

19th century marble especially white marble production, overall growth and extensively for construction of the emerging intermediate class.

20th century, mechanized production in marble processing, its use not only for decorative elements and used for wall cladding.

In the late 1950 of the 20th century to the mid-60, Italy, represented by stone mining and processing industry began fully into the automated machine production.

Second half of the 60, Diamond cutter into the stone processing industry late 80 early 90 into the stone mining industry, groundbreaking changes in the stone industry. Late 80 early 90 high-tech into the stone industry. From this stone industry changed the hulking figure, and as a snooty art products display in front of the world.

The late 80’s, rapid progress of the construction industry in the world, has contributed to international market demand for natural stone, which facilitated the development of its production. World production of native stone in the mid 80’s 23 million tons in 1989 to 30 million tons, respectively, per cent in 1926 and 20 times. 1979’s stone materials production has increased by 50% in the world 10 years. An average yearly growth rate was 4.1%.

Enter in the 1990 of the 20th century, despite the Gulf crisis, the Kosovo crisis, the Israeli-Palestinian violent conflict, events such as the India-Pakistan dispute over Kashmir, 9.11, brought turmoil to the world and disturbing, trend of the world economy at a low, but due to the emerging of stone rise of Nations such as China, architectural stone industry is still evolving.

Principles of Malachite Embossing and Engraving

Jade stone carving method is reduced in volume, solid character images such as landscapes, birds, insects, fish, jade stone in planes, arcs on the surface, usually only a decreased thickness, while maintaining the creative aspect ratio. Carver, images can be used to varying degrees of thickness was reduced, using different images of male and female face, formed under the effect of light refraction, or the perspective change of light or dark, exceptional carvings of icing and the sense of space, thus making the Emerald stone relief seems closer to painting, especially a thin Emerald stone reliefs like painting.
On the jade stone
Jade stone extends from Emerald mines out of the ground, has not yet been processed polished Emerald wool, bet, such as rocks and Ming. Also non-ferrous materials, flowers and so on classification methods.
About Emboss
So-called Anaglyph is the combination of sculpture and painting, using compressed approach to object, depends on factors such as perspective to represent three dimensional spaces, and only for one or two to watch.
Above is the explanation in Huian Kay rocks share jade stone reliefs, was also due to relief stress flat effect, theme scenery, environmental work can be filled and perfect performance in the relief.

The above work you need to be aware of are:

And excellent finishing
Means great/exquisite jade material carefully. A high quality of jade material, often with just a bit of carving without carving even, just give him a base, can be expected to be very chic.
Good jade is scarce. Most Malachite quality is middling. to utilize these materials is especially weighty.
Third, the small pieces
Complete with good jade of a high degree, is very small, which needs the sculptor unique mining maximum utilization of these minor pieces.
Four, getting pretty clever
Skin color of jade is the prevalence of these skin color if the sculptor is good, can play a finishing touch effect stone carving works. Conversely, easier to ensure that matters worse, it also stresses the difficulties.

The Utilization of Natural Stone

Stone is a natural non-renewable mineral resources in today’s growing demands will only intensify in the context of reducing, in advocating environmental protection today, the further development of the comprehensive utilization of natural stones, treasure, killed for profit has been made by hand. Comprehensive utilization of native stone, approach is very promising. Is currently being used and is only in the development of comprehensive utilization project is related to many aspects of life.

Comprehensive utilization of spontaneous stone, approach is very promising. Is currently being used and is only in the development of comprehensive utilization project is related to many aspects of life.

Mining of non-derelict stone

Top, bottom of the facing material deposits often has other minerals, namely non-derelict stone. Mining in general, and symbiosis in rock ore is also mined. Take advantage of it. Beijing Yanshan marble top (layer) great dolomite mine, Dali City, Yunnan province Cang sueing marble top (layer) talc mine. parental guidance Magma in the seam can be refined chemicals or fillers such as metallurgical industry, is that you can take full advantage of our resources and can increase economic benefit.

Non-specification of rubble, gravel

Natural stone mined in the course 50%, turned into rubble and gravel of non-compliance, national projections of current production blocks of stone, this is a very impressive numbers, if they can take full advantage of both the economic benefits and saving resources. Use for: as Shi Maoshi and gravel concrete for construction accessories, build embankments, roads and mushroom rock walls, and so on.

To produce granulated rubble and gravel crushing and screening you can get all kinds of stone M, its varieties, and colorful. Is the production of artificial stone, Terrazzo, granitic plaster and decorated with good raw materials.

Utilized in the production of artificial stone and polyester resins and cement blocks after mixing, vibration, vacuum forming. Made of imitation marble, artificial granite blocks, and then by grinding, cutting processing technology, such as decorating the plate.

Production of household products such as wood and stone furniture, stove, variety, selling faster, saves wood.

For carved, and technology products Yunnan province Dali, and Fujian province in Huian County, and Hebei province guying County, and Beijing Fangshan district, production stone crafts of history long, known as stone of township of reputation, by carved of tree, and flower, plant, Lions, and stone horse, and stone bird, and stone dog, animal; vase, and tea, and cookware, and lamps, and wine, and smoking, commodity; styling beautiful, and varieties pattern more, and bulk big, sells both at home and abroad.

Meet the technological requirements of part of the limestone and dolomite, calcium carbide, diabase, etc can be utilized for glass, ceramic, limestone, cast stone, concrete, alkali and other raw materials.


In the course of processing crude stone will generate approximately 5% blocks, one-third per cent of the total leftover. If as waste discarded, still have to pay a monetary price shipped out, improperly stacked also hinder environmental protection. In fact, these leftover are also very versatile.

1. Cut into various shapes and size tile, mosaic, corridors, Wadi, bathrooms and other small and small parts of veneer, durable, clean, neat appearance.

2. Using its natural shape, inlaid paving indoor field surface, walls and walkways of the Park, and so on. According to the cultivar texture differences, utilizing tonal matching aesthetics, spliced into a circle, square, triangle, vivid patterns such as flora and fauna for use after even more fun, beautiful and pleasant.

3. For the production of parquet wood and ice patterns of marble. Pattern facet of the stone is of different color bricks, bonded into large-size plates; ice line marble directly scraps pieces of large-size plates of different color, shape of the spring thaw of ice, hence get. Features both splice plates, tiles properly bonded properly, their value not inferior to the authentic (adult size) plates.

4. For the production of electrical insulating materials. Edgings can be made consistent with electrical appliances switch, light switches, switch cabinets, etc, is one of the indispensable material of rechargeable power industry, whose products sell well.

5. For road-track Board. Urban tracks lines with white natural stone inlay spelling, and clearly focused, once and for all.

6. Made of small crafts, small necessities. Made with leftover table lamp, desk calendar, pen, ink, painted bronze paperweight, color screen, table and door handles, and elegant appearance.

Natural stone stone powder

Crushed stones and stone products specifications Board processed into powder, is expected to have a variety of uses.

1. For the production of artificial sand, foundry sand and waterproof material, such as linoleum depending powder, steel casting, Tuomo, gradually smoothing, etc.

2. Chemical filler and paint fillers, architectural decorative painting.

3. Substitute baking soda, used for tanning. Using this process. It can reduce labor intensity and improve the production environment, and increase economic efficiency.

4. used for coal combustion and desulfurization agent for life, and join in the live coal of 5~10% marble, can not only save coal and combustion, reduction of sulfur dioxide gas escapes, improving indoor and outdoor environment, save energy, improve economic efficiency.

5. Production of welding electrodes joined stone powder. role to play to prevent weld pool and arcing into oxygen and nitrogen.

Waste rock slurry (slurry)

Each step and stone processing plants (sawing, milling, cutting), produces some waste pulp, if random emission, pollution of the environment. If precipitation, dewatering and drying (or dried), and other related processes, can be utilized as cement raw materials and asphalt filler, can also be used as fillers such as chemical dyes are used.

Dolomite powder factory, da Shi Wo town in Fangshan district of Beijing, is the treatment of waste rock, and as a raw material for cement production, supply Liulihe room mountain

Introduction and Installation of Natural Stone

Natural stones are native rock, and processed into a block or plate material collectively. Die stone for architectural decoration there are mainly two types of granite and marble.

marbles mean sedimentary or metamorphic carbonate rocks rock, marble, dolomite, limestone, sandstone, shale, and slate. As famous for white marble is Beijing Fangshan Middle dolomite, marble is produced in the county of Dali in Yunnan province of marble, the famous Green Serpentine silicide Kayan in Dandong. Similarly, as the stone mining of various types of igneous rocks, such as granite and andesite, called the slow, green, rock, gneiss granite diabase. Granite is the white granite of white tiger gully as Beijing. Jinan is green gabbro, while the Qingdao black granite diabase.

As decorative stone is a natural product, each plate pattern and color characteristics are not consistent, must pass the parquet (color), the pattern and the color are gradually extended, transition to achieve the overall tone. Place flowers (colored), shall immediately be numbered, so that when fitted in place. Number available and pasting labels or lumber crayon directly on the surface, but avoid using liquid crayon graffiti mark on the stone surface to prevent pigmented liquid permeating stone material, leave indelible traces.
When you install, first floor mud-daub with water layer, and 1:2.5 the bottom of cement mortar and rammed, leveling, and then poured over fresh mud posted solid stone. Best of cement-mortar thickness is not lower than mm. travel destinations . Within 8 hours of the paved stone do not walk or ballast to avoid empty shells or rough terrain. While it is important to point out, some imported stone affixed with plastic on the back the network, flaky network before installation which must be torn off.
Be aware of the fact of is that bathroom floors, wall decoration materials, although it can be a variety of materials, but only have one: to be waterproof. Stone of the sandstone class and may be used, even if a surface waterproof and do not take into account.
When the stone facing plates all the positioning fixation, refurbishment, due to the existence of monolithic stone facing plates are always flatness tolerances, combined into a single rugged flat seams will certainly exists, Shuhei joints or low are therefore indispensable link in the installation project. is another important work of clearing the surface of stone finishes stains. Mud stains in particular, should be readily cleared.

The Details of Bath Stone

Choosing of Bath stone

Due to the different concepts of homeowners, and coupled with the diversity of varieties and textures of the stone of the ever-changing, bath stone in color material are numerous, including granite, marble, limestone, sandstone, slate, quartzite, and so on. Usually bathrooms are marble and granite used by stone. (But now that concerns about radioactive granite, current use of granite has started to decline. )

Now, people generally prefer plain simple stone or solid colors or textures to decorate the bathroom floors and walls, decorated with the rich texture of marble sink tops. Bathroom adds to the air of elegance in a few minutes.

Marbles are also called metamorphic crystalline limestone or back. Solutions of genuine marble is a metamorphic rock of the stone, and has a crystal structure. Most marble derived is limestone geological changes. It was dominated by calcite and calcium carbonate. Mohs scale of mineral hardness value of 4.5 per cent. The drawback is the relatively soft, acid and alkali, poor weathering resistance, easy to absorb liquids such as oil, water contamination and is easily scratched, do not wear, and almost all of vertex containing acid and alkali cleaning and stains on marble has hurt, stay a little longer, damage to marble and lose luster.

In the marble bathroom utilize should be made of material harder, high density, avoid using soft materials, high water absorption of marble. Marble bathroom the best choice polished surface processing and protection treatment before utilize, so as to better protect the stone, it is easy to clean, and marble tile suitable for tiling of vertical surfaces. colored stone tolerance of mild soap and water pollution degree stronger than the dark stone, so it is recommended not to utilize in a toilet and bathroom black and green serpentine marble and stone surfaces contaminated with relatively little chance.

Bath stone cleaning and maintenance

Natural stone is a natural beauty, textures, unique upscale decoration material, surface natural stone look texture is dense and high hardness, but due to its natural and mineral structures, diversity, and the stone itself has many flaws and problems, in fact, natural stone is very precious. Laying natural stone requires not only installing and utilize caution when, in daily use should be noted at the same time take care and maintenance.

Toilet and bathroom special ambient conditions, moisture, humidity, mold, dirt and frequent contact with chemicals such as detergents, bath stone is very vulnerable to pollution, as soon as the maintenance is not good, it will corrode the surface of the stone, bereavement, or even stain color line.

So on a daily basis, you want to be careful not to use shampoo products containing dyes, don’t use SOAP and shampoo containing artificial colors, and do not use acid or alkaline washing products, neutral cleaning agent to clean the surface, try to keep stone surfaces dry, pollutants fall on stone surfaces should be wiped clean immediately, and so on.

The method of Reduced Wear from Powder to Diamond Segment

Corundum is human nature’s hardest material found thus far, but during the use, wear of the diamond powder is an issue that cannot be ignored.

Because diamond is human nature’s hardest material found thus far, so stone powder to its wear and tear is tiny. Nonetheless, the matrix is different. It is composed of various metal materials, hardness is lower than that of diamond, susceptible to hard granite particles wear, premature wear of the carcass will cause premature detachment of the diamond, vicious circle, directly affects the life of the saw blade. In order to reduce stone powder for diamond segment wear, you have the following options:

Stone powder purification method:

1, natural precipitation method

2, machine cleaning method

3 chemical flocculation

Practice has proved that the stone powder for diamond segment wear is a problem not to be ignored. It reduces the service life of the saw blade, and increased costs. the same time, during the process of recycling, which also has some wear on equipment, stone dust particles in the purification of coolant in a timely manner are essential.

In the above three methods of purifying stone powder, natural precipitation method suitable for clear powder particles larger; mechanical removal and chemical precipitation method suitable for clearing small particles of powder. Obviously, if there are conditions, three integrated utilize, the effect will be even better.

Top Ten Considerations for Conservation of Natural Stone II

Today, we continue to see the next steps keep the natural stone.

Under normal circumstances, water stains on the volatile off within a certain time, but in the bottom under the condition of extreme temperature, water stains will not disappear, will immerse and long-term storage from within the stone. Various stains material (except liquids) does not in itself has an impact on the stone, and only after the stains and produces chemical changes in Sheung Shui, will form a dye, pollution and other issues. In addition, water immersion within the stone, also changes the stone, stone mineral salts by contact with water and chemical reaction, when crystals grow large, stone will burst and precipitated crystals on the surface, causing pollution problems such as Rainbow. Therefore, conclusions water is the biggest enemy of stone. Stone pore clogging can only be fundamentally solved this issue.

“Prevention is better than cure” this quote for stone is the most fitting. Stone conservation aim is “to prevent moisture infiltration, moisture exhaled.” Stone protecting agent for different characteristics, stone provides comprehensive protection against the infiltration of moisture, dirt, grease, etc, will also prevent mineral salt was taken outside of the stone, rainbow or rust stains, etc.

2, avoid all contact with non-neutral articles

All stones are afraid of acid and alkali. For example: acid often results in oxidation of pyrite generation in puke yellow granite, the acid will break down calcium carbonate contained in a marble, causing surface erosion, alkali eroding granite crystals of feldspar and quartz silica in grain peeling caused by grain boundary phenomenon. So non-neutral articles are the engulfing of damaged stone mirrors.

3, and will not be waxed

Market where many kinds of wax, water based wax, acrylic, oil, stearic acid, and so on. These waxes are basically containing acid and alkali substances. Not only can clog the pores of the stone to breathe. Still stained with dirt and dust to form wax scale, resulting in yellow stone surfaces. At very sharp frequency of pedestrians and the circulation of goods place while waxing, you must consult a professional maintenance company with wax and maintenance.

4, not mess with non-neutral detergent

For the sake of quick cleaning results, General cleaners contain acid and alkaline, if prolonged use of unknown composition of detergent, will make the stone surface gloss loss and non-neutral reagent residues also have a primary cause of the stone material pathological change in the future.

5, not long-term cover carpets, debris

To keep the stone to breathe smoothly, avoid long covering carpets on stone surfaces and debris, or moisture cannot be changeable through the stones pores under the stone. The stone owing to excessive humidity, water content increased problems arising disturbing the stone material pathological change. If you must lay the carpet, dumping debris, and please don’t forget to always change.

6, thoroughly clean clean

Granite, whether hard texture (hardness of HRs88-111 4-7) or than the marble (hardness of HRs46-77 3-5) is not resistant to wind the long-term ravages of sand and soil particles.

Using electrostatic duster and MOP thoroughly from time to time to do the dusting and cleaning work. Entrance into a better place dust mat of commercial space, filtering the grit from shoes by. Home is best after getting started to change into slippers, reducing the chance of grit were stone dust surface.

7, regular upkeep and maintenance gloss

Dusting, cleaning alone is unable to keep bright stone glosses sustained retreat. So be sure to regularly make a professional company to do maintenance and regeneration of gloss maintenance.

Yank, stone material maintains with wax, not only expensive and time-consuming, and Prince is ammonia-containing substances, volatile decomposition had a negative impact on humans and the environment, has tapered off in the international arena. At present, crystal face processing is the best way to conserve.

8, do you want to eliminate the pollution

All stone with the natural pores, pollution (oil, tea, coffee, Colas, such as soy sauce and Chinese ink) will easily infiltrated inside the stone down the pores, forming annoying stains, so be sure to select a good quality stone construction, protective agents, stone on stone surfaces to prevent contamination sources of pollution. Need to know all the protective agents are not hundred percent long-term denials of pollution, so once the pollution on the stone must be clean to prevent the permeating stone material inside the pores.

9, always keep the air dry

Stone much moisture is too hefty. Hydration of water on stone, hydrolysis and carbonation, water spots, whitening, such as weathering, erosion, rust and yellow lesions, destroy stone. Stone installation sites always keep the air temperate.

10, to be applied on a regular basis for protective treatment

Long Stone life, denial of infiltration of water and pollution, it is important to regularly take professional protective treatment. Protective agent must pay extraordinary attention to the quality. construction, it must be feasible to maintain the breathability and waterproofness of the stone, stain-proof. Must not use unsolicited Protectant, so as not to not only measure up to the protective effect, increased stone maintena

Several Methods of Clearing Surface Wax Scale of Natural Stone

A, and what are the categories of the wax?

There are many Waxes on the market. Such as the water based wax, acrylic, oil, stearic acid, and so on. These waxes are basically containing acid and alkali material after long use, the pores can clog not only breathable natural stone, is also easy to make natural stone coated with wax scale dirt dust formation, causing yellowing phenomenon in natural stone surfaces.

Under of the following ways the classifications are

(1) The oily wax: Synthesis of solvent-containing wax. There are two kinds of robust and liquid.

(2)Emulsified wax: wax emulsion in water containing solvents.

(3) resin waxes: a metal consisting of propylene, polyethylene resins containing emulsifiers.

(4) natural wax: consisting of natural rubber.

Second, how the resin COATING on the floor wax film?

Resin film forming process for COATING on the floor:

(1) The Prince.

(2) The evaporation. Milk particles are filled.

(3)Milk particles mix, attachment.

(4) The completed film.

Three disadvantages of wax, resin use?

(1) floor and drape film poor contact. For example: the floor wet, low molecular weight is too large, plasticity, natural stone can cause disfigurement, pores are too small, too smooth powder.

(2) La’s shiny enough, only silky with no mirror effect.

(3) the epithelium is too thick not natural stone texture.

(4) leveling agent resin wax, effortless to turn yellow.

(5) The resin wax regularly in addition to Prince, but can damage the surface of natural stone.

(6) of inorganic alkaline salts have a crystalline wax removing agent, long-term residual crystallization expansion in the pores, resulting in rupture of genuine stone.

Four, how to remove the old wax scales?

Old wax scale removal methods:

(1) Coupled with aqueous wax removing agent S grinding.

(2) Spray waxes removing agent to use with scraper.

(3) To direct grinding watermills.

If it is a high frequency of pedestrians and the circulation of goods of natural stone floor, you need regular waxing, waxing professional maintenance companies should be invited to keep “breathe unobstructed.” In order to maintain the natural stone, “breathe”, and should be avoided in native stone covered with carpets and other debris, or moisture cannot evaporate natural stone the stone material pathological change due to water content increased, among other issues.

Top Ten Considerations for Conservation of Natural Stone I

Natural stone is by far the very high cost of building materials, using Westerners who want to highlight the value of sense of its strong decorative elements on structural factors, are already widely used in hotels, restaurants, office buildings, airports, memorials and other public buildings: floors, countertops and walk into the family, and so on.

However, due to natural stone formation of long, many marbles are formed by calcareous. Granite is composed of silicate minerals, it is easy to react with the detriment of stone maintenance chemicals. Genuine stone is just like your teeth, need careful maintenance and repair work, lack of attention to maintenance or maintained improperly, will make the stone a born noble, elegant temperament style disappeared. Therefore, maintenance of stone makes it permanently bright and pure, and is convenient for daily cleaning, is particularly important.

Talking about stone maintenance

(A) the necessity of the stone material maintains

The company engaged in conservation techniques for many years, often receive a number of builders or owners to inquire, mostly stone decoration is not acceptance, the stone material pathological change has occurred, had to seek remedies. In fact, these problems can be prevented completely, regardless of pollution and destruction of the stone where they come from, the underlying reason is that the natural cracks and pores of the stone itself, with absorption and permeability. Without a protective treatment, will inevitably lead to processing, storage and transportation, occurred during the installation and use of various diseases and pollution, speed up the weathering process of its corrosion.

Best way to solve problems is immediate protective treatment, eradicate the absorbability and permeability of stone, its mate lower water absorption and adsorption, permeating stone material transports moisture and pollution, disease cannot produce. In addition, lesion stone has already occurred, cleaned after the refurbishment, such as coloring, protection must also be addressed, due to previous lesions may appear again

(B) why rather than work through the crystal hard waxing for stone maintenance?

People know that if stone ground without conservation, will soon lose its value there will be wear and tear. Waxing is the most currently used in China’s hotel industry a approach of maintenance of stone material ground, it can be said it is a mistake to maintenance. Why? because wax is a not breathable of sealed agent, hit finished wax Hou, while outside of water and moisture cannot entered stone internal, can in must degree Shang prevent pollution, but stone internal and following of moisture due to sealed wax of effects also distributed not out, such moisture long-term accumulated in stone internal, on will led to stone of lesions; and wax General will effects stone of natural color, while often waxing will damaged stone surface, shortened stone life. Besides, waxing wax regularly, and cured most of the water is a brilliant (PH12-14), marble (marble) rapidly aging because of corrosion of calcium carbonate. Very high corrosion resistance of quartz granite, feldspar and Mica is not resistant to corrosion, pitting deepened the widening, the surface becomes uneven.

Crystal stone facing of hard is by far the most ideal maintenance way, the principle is the use of ceramic hard agents plus the floor brush to the stone surface friction, under the dual role of chemistry and physics, causes the ground to the surface hardened layer form a hard dense ceramics, stone facing to be easily damaged, do not stick dye stains. Stone face crystal hard treatment did not change the structure of the stone is not coated with a layer of mulch, therefore, does not change the texture of stone. After Crystal, hard, stone surface molecules more dense, improved the gloss, makes the stone more beautiful, more elegant. Crystal unkind dealing with new stone facing, or refurbished stone surfaces begin, and regular maintenance, the stone face perfect, for years and like new. addition, the crystal hard stone or patching, slightly damaged as the ground, should be refurbished, then crystal hard.

Advantages of Crystal face processing:

1, gloss natural, does not affect the breathability of stone.
2, wear-resistant: Duration is water wax several times.

3, time: does not change the chemical composition of stone, so as to avoid stone illness. Crystal faces processing by users and loves it.

(C) maintenance of stone-notes

1, pay attention to the waterproofing

Stone pollution can be divided into the following four categories:

⑴ Organic substances such as cigarettes iodine soy sauce stains, stains, stains;

⑵ Metal rust stains such as rust, stainless steel, lead;

⑶ Oil such as petrol, oil, painting;
(4) is the easiest and the most difficult to avoid water stains.
