Stone is mainly divided into two categories: natural stone and artificial stone. Natural stone includes granite, marble, sandstone, slate, etc., which have the characteristics of high hardness and natural texture;

The main types and characteristics of natural stone:

Granite: Igneous rock, with the highest hardness (Mohs hardness 6-7), acid and alkali resistance, weathering resistance, suitable for outdoor use. Common domestic varieties include Fujian Hetang Red, Sichuan Red, and imported varieties such as Indian Red and Brazilian Illusion Green. The main colors are red, black, green, gray, white, and yellow, with uniform textures. ‌‌

Marble: metamorphic rock with moderate hardness (Mohs hardness 3-4), with a brilliant texture but easily weathered, commonly used for interior decoration. White marble, called White Marble, originated in Dali, Yunnan. ‌‌‌‌

Sandstone: Sedimentary rock with strong graininess and high water absorption, suitable for facade decoration. Common colors are brown, yellow, and gray. ‌‌‌‌

Slate: Metamorphic rock that can be peeled into thin sections, with a hardness between sandstone and granite, commonly used for walls or small area paving. ‌‌

Surface type of stone processing

Burnt surface: High temperature explosion forms a rough surface, which is non slip and weather resistant (commonly used in granite). ‌‌

Polishing surface: mirror gloss, requires regular maintenance (suitable for marble and granite). ‌‌

Litchi/Pineapple Noodles: Artificially chiseled textured texture to increase slip resistance. ‌‌

Stone, as an important material for architectural decoration and carving, has a wide variety of types, distinct characteristics, and is widely used. Firstly, stone can be classified into granite, marble, limestone, sandstone, and quartzite according to their types, each with its unique texture and appearance. Granite is known for its hardness and wear resistance, making it suitable for high-strength applications; Marble is favored for its elegant polishing and stability. The common characteristics of stone include good wear resistance, strong compression resistance, corrosion resistance, and significant aesthetic effects, but at the same time, the price of stone is relatively expensive. In architectural decoration, the application of stone is ubiquitous, from indoor floors and walls to building facades, and even artistic carvings, stone can showcase its unique charm. In addition, stone is widely used in the construction of infrastructure such as bridges, cemeteries, and water pools, as well as in the design of landscape gardens. Therefore, when selecting and using stone, it is necessary to fully understand its types, characteristics, and maintenance requirements to ensure the long-term beauty and durability of the stone.
