(I) Consideration of Budget Capital

Natural stone belongs to the category of natural ore. Due to variations in quality, quantity, and mining locations, different types of stone often have significant price differences. Therefore, when owners and designers select them in the initial stage, they should have a corresponding understanding of their costs.

Expression of Aesthetics

Stone colors, patterns, and textures are subjective factors in selection, often differing due to the preferences of owners and designers. However, with a deeper understanding of natural stone, the expression of design craftsmanship can be more exquisite and adaptable.

The classification of ore formation primarily includes igneous rocks, sedimentary rocks, and metamorphic rocks. Locally, construction stones commonly used are mainly marble (metamorphic rock) and granite (igneous rock). Generally, marble stones feature abundant colors and patterns, with a smooth and soft texture. Although granite has fewer variations in color and pattern, it exhibits a more flexible texture. Additionally, granite has a more solemn and classical overall feel.

Section 3: Stone Quality Control

Uniformity and integrity of materials:

Avoid dark cracks, black spots, and color discrepancies as much as possible.

2. Composition of Stone:

(1) Avoid excessive amounts of harmful substances such as iron sulfide, iron oxide, salt, carbon, and clay in stone.

Avoid radiation components in stone materials.

(3) Avoid minerals with excessively high coefficients of thermal expansion, thermal conductivity, and electrical conductivity within the stone to prevent risks of cracking, thermal conduction, and electrical conduction.

(4) Durability Considerations

When using stone as a building material, it is generally desired that the stone has the same lifespan as the structure itself, especially when used for exterior wall and flooring finishes, where durability becomes even more crucial. Stones with good durability not only ensure the aesthetic appeal of the building's exterior but also guarantee the stability of the stone, preventing potential injuries to pedestrians in case of falling. However, installing stone on building exteriors and floors poses a significant challenge to the stone itself.

Consideration of Application Parts

When stone is used for exterior walls, flooring, high-rise buildings, or other unique outdoor environments, the selection of stone type becomes even more crucial.
