Reflectivity: Marble stone has a smooth and reflective surface that gives it a luxurious and beautiful appearance. This property makes it suitable for use in ornamental and decorative materials.
Transparency: Some types of marble have a natural transparency, which is called transparent marble or crystalline marble. This feature is observed in some cases of marble and gives more beauty to the stone.
CHEMICAL PROPERTIES
chemical properties:
Chemical composition: Marble is composed of calcium carbonate. Its main chemical composition is calcium carbonate (CaCO3), which is present as crystalline crystals in the rock structure.
Solubility: Marble has solubility in acids. For example, sulfuric acid and hydrochloric acid can dissolve and leach marble. This feature is used to clean the marble surface.
Water absorption: marble can absorb water due to its porous structure. This property limits marble in some uses.
