Stone Material
Stone, referring to rock in the scientific term, such as marble and granite, are abundant in the nature. However, not every stone has commercial values. Most rock stones exposed on the earth can't be used in architectural applications due to unfavorable physical and chemical characteristics. It takes geologists many years to discover one usable stone quarry.
Stones have three general origins: sedimentary rock formed through deposition in the oceans or rivers; igneous rock that is associated with lava activities, and metamorphic rocks formed when high temperature and pressure altered the mineral structures in original sedimentary or igneous rocks. Granite is a typical igneous rock formed when lava cooled down deep under the ground. Such process contributed to hardness and toughness of granite we see today, making granite a great stone for applications requiring weathering proof. Limestone and sandstone are common sedimentary rocks; they will be altered to marble or slate after being metamorphosed. In terms of production process and commercial applications, stones are often classified into cut stone and carving stone. Certain marble and granite suitable for stone fabrications may not be used for carvings.
