I. Damage caused by physical damage: including freeze-thaw damage and crystallization damage. Freeze-thaw damage occurs when the temperature in the winter is cold. When moisture enters the stone, it freezes and expands, causing the stone to expand and crack. Refers to the salt dissolved in water that penetrates into the yellow rust stone through the lifting effect of the capillary. Under dry conditions, the salt constituents crystallize. The pressure caused by the crystal expansion causes the surface of the stone to fall off in powder or scale form, and dry. In the case of wet alternation, the crystal damage is more serious.

Second, chemical corrosion damage: rust spots, water marks, Baihua and other diseases are caused by stone pollution or corruption.

The microorganisms will not only damage the appearance of the stone, but also cause the stone to change color.
