Stone is a non-renewable resource and seldom used, so the government has introduced a series of measures to limit the exploitation of stone. The stricter the government control, the more tense the market will be, thus raising the price of stone. The current price of Sesame Blackstone is a typical example.

After the stone price rises, in order to occupy an advantageous position in the market competition and get orders, some manufacturers will also choose some inferior stone materials to be shoddy. Therefore, it is very important to have a pair of discerning eyes. To accurately distinguish the advantages and disadvantages of materials, the first thing is observation.

High-quality granite stones are generally hard and delicate, with good texture. The Buddha statues carved with this stone can effectively use the particularity of their own materials to show the charm of the statues and can be preserved for a long time.

Second, identify the stone Buddha statues from the carving knife method.

The ancient stone carving knives are concise, skilled and smooth, but the author of the replica is not familiar with the style of the times, technological process and carving method of the original, so the new works always leave their own style traces.

3. Identify from the stone density of the stone carving Buddha statue.

Even though most stone buddhas have the same appearance color, they may be different mineral materials. Different kinds of stones have different densities, and the quality of stones can be judged by the dispersion speed and range of ink drops.

At present, some stones on the market are artificial stones and some are inferior stones. It takes a long time for high-quality stone to disperse after ink drops, and the range of dispersion will not be very large. And artificial stone or low-density stone, soon dispersed.

Extended data:

1, the color of stone carving pattern on the surface is not beautiful as decorative stone carving. People mainly pay attention to the decorative effect of the processed surface.

2. Poor physical and chemical properties. Decorative (that is, the color pattern, luster and appearance quality of the stone carving surface) is often used as the requirement of material selection. However, in evaluating the quality of stone carving, besides decoration, other quality indexes should be considered, such as compressive strength, flexural strength, durability, frost resistance, wear resistance and hardness.

3. The deviation of specifications and dimensions is too large. Ornamental stone lions are all processed into plates. During construction, the method of paving (when the ground is used) or collage (when the wall is used) is adopted. In order to ensure that the decorative surface is flat and the seams are neat, the national standard stipulates the deviation of the length, width and thickness of the plate, as well as the limit tolerance of the surface flatness and the included angle between the front and side of the plate.

4. The appearance quality of the processed plate is poor. After cutting, sawing, grinding and polishing, the surface features of natural stone carvings are completely exposed. In the process of processing, the surface appearance of stone carvings will leave some defects. If these appearance defects exceed the scope stipulated by national standards, stone carvings are unqualified products.

Using these inferior plates with poor appearance quality for decorative stone carving, the overall decorative effect will not be satisfactory. Therefore, when judging the quality of stone carving, it is suggested that besides the color of the pattern, the appearance quality of stone carving must also be checked.
