How to judge the quality of white marble?

White marble has small transparent crystal metamorphic diagenesis, which sparkles and crystal clearly under the light, like the

beauty of rime. Compared with other marble colors, white marble with excellent whiteness always brings people a feeling of

hig-end and cold.

White marble is mainly divided into two categories, one is coarse-grained crystalline texture, and the other is fine-grained crystal.

The whiteness and fineness of white marble are the keys to determining the value of marble. At the market,higher price white marble

is always  with fine grain texture, such as Volakas white, snow white, statuario white, and of course, calacatta white. The crystal particles

of this variety are very fine, and it is difficult to see with the naked eye the marble crystals,the textures are very delicate and have a good decorative effect.

Every year, the world's top engineering designers and high-end decoration projects use these marble works as benchmark works, making surrounding projects follow suit. The reserves and output of fine-grained white marble are very small, and the supply can not meet the demand, so the price has remained in high level.

So why does the same material has so many differences in value&cost? Everyone knows that marble is a natural product, there is a rule of

20-80, the raw materials are divided into different grade. First of all, look at the whiteness of white marble base and measure the whiteness

of the substance. Usually, the standard whiteness of magnesium oxide is 100, and the whiteness of newspaper is about 60. Based on this, if the whiteness of white marble is higher than 90, it is good white texture. The whiteness of same material and same quarry is also different. This whiteness and fineness are the main factors that determine the price of white marble. Oiliness is also one of the judging criteria. For example, the common material Carrara white, people mostly take oiliness to judge the price of Carrara white marble. Oiliness is the comprehensive performance of marble's luminosity, density and hardness, and this concept also applies to other marbles.

Another point of quality criteria is the aesthetics of the slab texture. Compared with the oval, spot, and line textures, most people prefer to larger flowing textures or more uniform colors. In order to balance supply and demand, people differentiate the prices of textures of different shapes. The natural texture is formed by the deposition and geological changes of nature. Each natural stone is imprinted with different imprints of nature, which are rich in stone customized art by designers. The so-called benevolent sees benevolence, and the wise sees wisdom. Everyone has their favorite natural artistic patterns in their mind, and those who can tolerate imperfections and beauty are always open-minded and loving. In order to simulate the natural marble, artificial stone also prints the color and vesin design on its own products. Most of the porcelain tile patterns with same texture are gradually eliminated by the market, so we do not need to pursue the consistency of marble texture, it is natural to have differences.

What's the advantage of white marble?

First of all, White marble is elegant and noble. The white reflection reflected by the natural transparent crystal is immortal and has excellent texture. This is the main reason why people love white marble.

Second,Natural white marble formed the Cambrian Qianhai Continent, and the salt lake environment that was dry and rapidly crystallized, especially fine-grained white marble with good whiteness, there are very few of these marbles in the world. Humans mine white marble in

the surface ore layers. These mines are all eroded by wind, sun, rain and geological changes, and there are natural gaps, stone lines, stone spot and other defects that affect the appearance. In order to avoid all kinds of flaws in the ore layer, people mostly use higher-cost mining methods, such as the method of down wall and hole mining. In order to improve the line of each layer of the big board, it also increases investment risk and gambling for mining people and investors. The yield rate of many white mines at the beginning is less than 1%, which means that investors need money to pave the way for mines. It is no exaggeration to say that the fine-grained white marble is the top merber in the stone family.

Third, as a decorative surface material, white marble symbolizes light, simplicity, innocence, tranquility, cleanliness and elegance. The world-renowned mosques must be decorated with white marble. The Taj Mahal in India is also made of white marble. Many Buddha statues in my country are also carved with marble such as marble sculpture, and they also appear in the Forbidden City, Yuanmingyuan and other ancient Huangling, which is enough to prove the charm of white marble. In terms of design, it is more in line with the decorative effect of light luxury, minimalism, Chinese modern and other styles. A residence decorated with white marble always brings a noble feeling.

How to reduce the problem of white marble after installation?

Most of white marbles turns in yellow, pollution, sandification, softening and other phenomena before and after laying, and the cost of

repair or replacement is not much more than the purchase cost of the marble.

First, water is the medium for returning to alkali. White marble will not return to alkali or turn yellow in a dry environment. Therefore, when paving white marble, first level the floor or wall, and then use white stone to pave it after the cement is dry. The patch is paved with marble. This paving method is suitable for projects with ample time, and the risk of white stone yellowing and darkening is significantly reduced.

Second, the waterproof sealer of white marble is very important. It must be sealed to make it waterproof during production and processing.

It is also required that the marble is completely dry, and the front and surrounding areas should be waterproofed. On the marble surface,

it is in the shape of water droplets, and the waterproof effect is good, which can block water, vinegar and chili oil, and is durable.

Third, before laying white marble, it should be checked that there is no rust-prone metals such as iron or wood sawdust and other easy-to-finish debris at the bottom of the installation. These debris will continuously release color under the catalysis of water. These colors are like dyes. Severely pollutes the marble from the inside up. Remember to clean up before installation. The hardness of white marble is related to water content. Whether in production, processing or installation and paving, try to keep the marble as dry as possible, which can largely prevent the problem of marble polluted, because white is more obvious than other colors of marble after water vapor polluted.
