Color and gloss of stone
The color of the stone refers to various kinds of minerals in rocks of different wavelengths of visible light selective absorption and reflection of various colors in the eyes of the people, by the feeling of showing. But the gloss is stone polishing face reflection ability of visible light. Beautiful color stone and a bright shine on people's shiny is with its mineral composition and structure, the structure is closely related to.
1.granite
The basic components of minerals are quartz, feldspar granite stone, hornblende, olivine and pyroxene, biotite, the former two known light colored mineral, after the four called the dark minerals. The type and content of quartz, feldspar in granite color depends on. The general contents of quartz and feldspar, is stone light color. When no dark minerals (dark mineral content is less than 5, the formation of white granite (petrology called alaskite), such as Jiangxi Fenyi the white lotus. When there is a certain amount of dark minerals, is the formation of various gray and gray series of granite, the former such as Fujian, Quanzhou white, the latter as Hubei Huanggang sesame gray.
The majority of granite in the quartz is a colorless or milky white quartz transparency is more big, light absorbing more strong, reflecting less light, the gloss of stone is low. Quartz is sometimes with white, yellow, purple and other color, also have a considerable impact on the overall color of the rocks.
2. marble
Barium color Dali line and the content of the letter, and materials such as bamboo, colored mineral elements content Ji low appears white copper containing a green or blue, with pale red drill, drill soap containing is rose red, iron yellow, containing strontium containing bluish green or yellow. serpentine soap green, with Shi Qiang or hunger quality early black, gray and black etc.
Large stone gloss with calcite and dolomite containing my line and their crystallization degree increased with the minerals, the content of impurities mud containing access increased.
3. slate
Slate varieties according to the color and gray, with blackboard stone, slate, green board line, Huang Banshi, red slate, violet plate, Cong plate for, rust rust and yellow stone fiber. Mineral composition of slate complex, most mountain stick on minerals, plate for color by clay minerals with different impurities, and dyed a different color. Pure straw color near green white, high organic matter in black. Slate plate foliation if Ding Muscovite person starry feeling, such as river Nan Lin county 'ArgentCrystal board for'.
