When making rockery for landscaping, when selecting materials, you should tap the stone to see if there is mute crack sound, and observe whether there are old cracks in the section after sawing. If the above situation does not choose; if you want to use, carefully calculate how to avoid, processing eyes, ears, force skillfully can prevent damage.
No matter what kind of stone, we must first understand its texture and structural characteristics, in the processing will be due to force, from the point of view of the most bearable processing is not easy to break. In processing, the angle and strength of each hammer and pick should be considered according to the shape structure and rock texture structure. The processing of thick and thick parts should pay attention to whether the vibration of weak parts can be tolerated. Don't think that the processing of thick parts is reckless, and ignore the damage of weak parts after the earthquake. Even if the processing of weak parts pays attention to light handed and light footed, and does not pay attention to the study of stress angle, it will cause rock fracture damage.
Therefore, in processing, it is necessary to know the central part of the rock to be processed and the impact and vibration limit that the rock can bear when applying the force, so as to know how to apply the force. This is a skill based on feeling and experience. As long as attention is paid in processing the rock, damage can be avoided or reduced.
When processing, the mind should be concentrated, not distracted, otherwise it is easy to cause rock fracture, rockery production is a technical work! Modeling should be simple and natural, no affectation!
