Natural decorative stone is processed from natural stone, so its quality is determined on the one hand by the quality of the block, and on the other hand is related to the processing process. So, how to identify poor-quality marble and granite slabs? Next, let's take a look with FABULOUS editor.
Poor physical and chemical performance indicators
The compressive strength, flexural strength, abrasion resistance, durability, hardness and other properties of poor-quality stone are all poor, and the durability of the stone cannot be guaranteed.
The pattern on the surface is not beautiful
The surface pattern of high-quality stone is beautiful and elegant, graceful and luxurious, making the decorative surface have a strong decorative effect. The surface pattern and color of the inferior stone after processing is not beautiful and cannot give people the enjoyment of beauty. Therefore, the color tone of the stone surface pattern is the main indicator to evaluate the quality of the stone.
The appearance quality of the processed sheet is poor
During the processing of stone, some defects will be left on the surface appearance. If these appearance defects are beyond the scope of the national standard, the stone is considered unqualified. The overall effect of using these inferior stone with poor appearance quality for decorative decoration will be very poor. Therefore, when judging the quality of the stone, in addition to considering the color of the pattern, the appearance quality must also be checked.
The size deviation is large
Decorative stones are all processed into plates for use, and the construction is done by tiling or collage. If the boards with large deviations in specifications are laid, the surface will be uneven and the seams will be uneven, especially for facade decoration, the line shape of the decorative surface will be irregular, which will affect the overall decorative effect. Therefore, the deviation of the specifications will directly affect the decorative effect of the stone.
