The cobblestone took one kind of pure natural stone material, takes since has experienced surely the year ago diastrophism in the granulated substance rocky mountain which sticks out by the ancient river bed produces, is experiencing in the mountain torrent impact, the running water transporting process the unceasing extrusion, the friction. In tens of thousands of years vicissitudes successional variation process, they full fetch water after the wave the movement which flushes, is rubbed by the broken stone collision has lost the irregular edges and corners, also deeply is buried together with the silt in underground has silenced 11 million years.
  Because these pigment ions dissolve into in the silicon dioxide hydrothermal the type and the content different, thus presents the color which the shade, the depth is eternally changing, causes the cobblestone to present black, white, yellow, is red, dark green, the schungite isochromatic department.
  Cobblestone use:
  The cobblestone is widely applied to the public building, the villa, the garden construction, lays down the road surface, the park rockery, the bonsai packing material, botanical garden art and other high-level overtop structures. It both propagates the Eastern ancient culture, and manifests the west classically, is graceful, returns the artistic style which plain returns to original condition.
  
  The cobblestone for only the water, the sewage treatment, the electric power, the botanical garden and so on a project has also provided the high quality material. Also for the ceramics, the precision casting, the papermaking, spurts rubs, the chemical industry, the monocrystalline silicon, the national defense and so on provides the original auxiliary material.

  Cobblestone material quality: 95% above silicon dioxide (SiO2).
  Cobblestone performance parameter: fineness 98%, compressive strength above 600 Kg/M2.
