How to judge the quality of white marble

The white marble has small transparent crystal metamorphic diagenesis, which sparkles and crystal clear under the light, like the beauty of rime. Compared with other color marbles, white marble with excellent whiteness always brings people a sense of high and cold.

White marble is mainly divided into two categories, one is coarse-grained crystal 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 price, there are thousands of marbles with only fine grain texture, such as Yashi white, snow white, large white, and of course, fish maw white. The crystal particles of this variety are very fine, and it is difficult to see the marble crystal with the naked eye. The fineness of the marble crystal is very good, and the decorative effect is good.

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. However, the reserves and output of fine-grained white marble are very small, and the supply is in short supply, so the price has remained high.

So why does white marble have so many differences in value?

First of all, look at the whiteness of white marble 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.  The whiteness of unified varieties and unified mines 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 Carrara white, merchants mostly use oiliness to locate 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 value evaluation criteria is the aesthetics of the board texture. Compared with the oval, stone scar, stone gall, and stone line textures, most people prefer larger flowing textures or more uniform fine lines. In order to balance supply and demand, merchants differentiate the prices of textures of different shapes. The natural texture of nature 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 and customized art by designers. The so-called benevolent sees benevolence, and the wise sees wisdom. Everyone has their favorite natural artistic patterns in their hearts, and those who can tolerate imperfections and beauty are always open-minded and loving. In order to simulate the naturalness of marble, artificial stone also prints the color line stone scar on its own products. Most of the patterns of tiles are printed with a single texture and are gradually eliminated by the market, so everyone better not pursue the consistency of marble textures, and it is natural to have differences.
