The main minerals of marble are calcite and dolomite, which are a type of rock represented by marble, including calcium carbonate salts and metamorphic rocks. Marble varieties and colors are different in different regions, so different origins often have the same rock with different names and different rocks with the same name. The phenomenon occurs, that is, the name is the same, or the name of the same region is the same. The relatively simple marble should be white or off-white, but because it is easily contaminated by other colors, different color series appear, mainly including white, black, red, green, yellow, gray and other patterns with patterns. There are many basis for the naming and division of marble. Dandong Green and Tieling Red are named after the place of origin and color; Marble still uses traditional names, such as Han Baiyu and Foshan White.
White marble is produced in Fangshan, Beijing and Huangshi, Hubei. It is mainly jade white, with slight veins. The veins are fine and layered, and it belongs to the highest-grade stone. Yashibai is produced in Greece, and there are many similar Yashibai stones in China. It is white with high purity, large-grained crystal structure, high hardness, smooth color, dense structure, and a little gray texture. Snowflake White is produced in Yexian County, Shandong Province. It is white and light gray, with uniform medium crystals and more yellow spots. Foshan White is produced in Hezhou, Foshan. It is mainly white with gray lines, high gloss, slightly larger grain crystals, and gray lines. Coarse, with many gray grains, some with beige grains, belonging to the low-end stone material, very suitable for engineering stone selection Large white is produced in Italy, the white background is mixed with gray stripes, the texture is relatively hard, the pattern is natural and smooth, and the texture is very layered Feeling, gray and white, distinct layers.
Generally, monochromatic marble requires uniform color; colored marble requires patterns and gradual transitions in depth; patterned marble requires clear patterns, bright colors, and strong pattern regularity. In short, it is better to have beautiful designs and colors, facilitate large-area splicing and decoration, and be able to supply the same color in batches.
