Choose a good grade: According to the allowable deviation of specifications and dimensions, the allowable tolerance of flatness and angle, as well as the appearance quality, surface finish and other indicators,blue grey limestone are divided into three grades: excellent, first-class and qualified; the classification of blue grey limestone.The identification is mainly through the detection of instruments and measuring tools.

Check the appearance quality: the appearance of different grades of blue grey limestoneis different. Because blue grey limestone is naturally formed, defects are inevitable. At the same time, the pros and cons of processing equipment and measuring tools are also the cause of sheet defects. Some boards are not full (warped or dented), the board has defects (cracks, sand holes, stains, etc.), and the board specifications are different (such as missing edges and corners, board irregularities) and so on. According to national standards, all grades of blue grey limestone are allowed to have certain defects, but the superior products are not so obvious.

Choose pattern color: The blue limestone slab is colorful, with various tones, and the pattern is not the same. This is the precious charm of the blue limestone slab. Basically the same color tone, small color difference, and beautiful patterns are the specific manifestations of good varieties, otherwise it will seriously affect the decorative effect.

Detection of surface gloss: The level of surface gloss of blue limestone slabs will greatly affect the decorative effect. Generally speaking, the polished surface of high-quality blue limestone slabs should have mirror-like luster, which can clearly reflect the scenery. However, due to the different chemical composition of blue limestones of different qualities, even products of the same grade have great differences in gloss. Of course, the glossiness of the surface of the board between different grades of the same material will also have a certain difference. In addition, the strength and water absorption of blue grey limestone are also important indicators for evaluating the quality of blue limestone.
