What things in your home are made of rocks or minerals, and why do you use them?

Natural marble brick is cut and polished with natural marble, ceramic tile is made of kaolin and other minerals, cement is made of siliceous minerals, only made of metal minerals, glass cover of desk lamp, etc. Things made of rocks are more durable and applicable, and things made of minerals are more applicable.

Rock is a solid aggregate with stable shape, which is composed of one or more minerals and natural glass. Rocks made of minerals are called monazites, such as marble made of calcite and quartzite made of quartz. Rocks composed of several minerals are called composite rocks, such as granite composed of syenite, feldspar and mica, gabbro composed of basic plagioclase and pyroxene, etc. Liquids without a certain shape, such as oil, natural gas and loose sediment, are not rocks.

Minerals are natural compounds with certain chemical composition, stable phase interface and crystallization habit. The crystal morphology and symmetry of minerals are determined by internal crystallization habits; The hardness, luster and conductivity of minerals are determined by the nature of chemical bonds. The color and specific gravity of minerals are determined by their chemical composition and the degree of bonding. When identifying minerals, the morphology and physical properties of minerals become the most commonly used symbols for identifying minerals because of their easy identification.
