What stone is used for carving?

The quality requirements of stone suitable for carving are generally:

1, rocks and carved stones belong to the category of rocks, and only with the characteristics of rocks can they be carved;

2, toughness, hardness should be below 3 degrees, only carved parts;

3. The quality of stone can reach the size and fragmentation required for carving;

4, artistry, to have the color, luster and corresponding texture needed for artistic creation.

Stone carving is a very old art form, dating back to prehistoric times. One of the most famous sculptures in the world, Michelangelo's David, was completed on 1504, using marble. Besides marble, common stone carvings include granite, limestone, sandstone and talc. The choice of carved stone depends on the sculptor's carving experience and project scale.

First of all, we need to understand different rock types, including sedimentary rocks, metamorphic rocks and volcanic rocks. All the stones used for carving belong to the same category. Knowing the characteristics, hardness, luster and durability of each stone is helpful to choose which stone.

Secondly, the choice of stone carving depends on the professional knowledge level of the sculptor. Soft stone is easier to carve than hard stone and is more suitable for beginners. The varieties of soft stone include talc and striped marble.

Third, see if local universities or colleges offer courses in stone carving. The professor can recommend materials suitable for this project and where to buy them locally. If you want to transport stones from other places, the cost may be higher.

Fourth, do a good job in stone budget. Some stones are cheaper than others because they are plentiful in the market. Very high quality stones, such as carrara marble, are very expensive.

Fifth, decide what color to use and how high the quality of the finished product is, such as how high the final gloss of the product is. Each stone variety is different in texture and color.

Sixth, think clearly whether to display the sculpture indoors or outdoors. Some kinds of stones can withstand strong weather damage. Granite is hard and kept outdoors for a long time. Striped marble, sandstone and talc cannot be placed outdoors.

Seventh, you should have an idea of the fineness of stone carving. As a soft sedimentary rock, limestone is suitable for very detailed carving. On the other hand, granite is too hard to carve carefully.

Stones unsuitable for carving

The more pores a stone has, the less it can adapt to wet weather. When the rain falls on the porous sculpture, it will gradually penetrate into the stone. This may cause it to break, especially when the water freezes.
