natural stone is formed by different kinds of minerals, for example, calcium carbonate is the natural consolidation component of marble. Certain viscous minerals are doped with calcium during the formation of the stone, resulting in brilliant colors. The beautiful patterns of marble are formed by the flow of liquid minerals from the rock under the action of high temperature and pressure. At high temperatures, the liquid minerals can flow, and when cooled, the mineral flow stops flowing and gradually hardens into a beautiful pattern.
stone correspond to the following:
black: biotite, amphibole, carbon
brown: limonite
ash: various minerals
green: mica, chloride, silicate
Red: Hematite
white: feldspar, calcite, dolomite
yellow: limonite
because minerals have various crystal properties, different properties have different colors. The main minerals and their colors are as follows:
pyroxene: brown, green, black, purple
biotite: black, brown, green
Calcite: Pearl and off-white
dolomite: colorless, pink, light brown
feldspar: yellow, white, pink, green, gray
Hematite: metallic ash, black
hornblende: green, yellow, brown, black
limonite: black, brown, yellow
sulfur: light golden yellow
important to note that if you use incorrect cleaning agents or non-stone conservation-specific cleaning agents, the use of dirty water mopping, may change the subtle color of the stone. Long-term exposure to the sun can also make natural stone fade.
