Stone materials refer to materials formed by the mining and processing of natural rocks, whose properties are determined by mineral composition, structure, and formation environment. Common types include granite (composed of quartz and feldspar, hard and wear-resistant, suitable for outdoor ground), marble (mainly calcium carbonate, with delicate texture, mostly used for interior decoration), sandstone (with granular structure, good air permeability, often used as wall materials), etc.

Stone materials have both durability and natural beauty, with strong pressure resistance, but some varieties (such as marble) are afraid of acid erosion. In addition to architectural decoration, they are also used in sculptures, crafts, etc. The differences in hardness, water absorption, and color of different materials make their application scenarios have different focuses.
