Tomb stone processing and processing

design headstone stone is subject to a surface treatment of the block before the production, and according to the different processing techniques, the final stone type is also varied, and the suitable place for use is still not the same. Tombstone stone surface processing what kind of process it?
  The first kind: grinding. After grinding, the surface of the stone is relatively flat, and the gloss can be controlled as needed. The surface gloss is very high, very smooth but there are a lot of tiny holes, this kind of stone is very common in everyday construction, because when the grinding is done, the floor has a large hole size angel headstones, which requires the frequent use of a penetrating sealant. The color of the stone is not as bright as the surface of the polishing process.
  The second: polishing. Although the stone of this step will be more glossy than the polished stone, it requires careful maintenance later, otherwise it will lose its luster after a period of time due to improper maintenance. After polishing, the surface is smooth and has few holes, showing the natural stone mineral particles.
  The third kind: fire. This process is the stone formed at high temperatures, the surface of the stone will be rough. Due to the high temperature heating, the crystal of the stone will burst and there will be many empty surfaces. It is necessary to use an osmotic sealant.
  Fourth: sandblasting. A high-pressure jet of sand-water mixture is sprayed onto the stone to form a shiny but not smooth stone surface.
  These types of stone are the most commonly used tomb stone processing procedures. Different tombstones do not have the same tombstone effect. Therefore, it is recommended that consumers must carefully and carefully select the appropriate tombstones when they purchase custom tombstones.
