Travertine (in French: Travertin), a porous limestone that category is accessoriesDecorations sedimentary rocks. in water resources, lower, lighter stone color determines the color of the stone will be. except elements during its formation, several factors involved in changing the appearance and rock mechanics Darnd.yky of the most important factors, thermal metamorphism travertine thermal Ast.dgrgvny on travertine causes less water absorption, condensation close to the time change and the elements added to a solution of water Could heating deposition time, it gives different forms. Other factors such as tectonic fractures and alluvial deposits, Lvvym etc. and for secondary factor in the appearance and quality of the rock is impressive. Travertine has a porous texture and colors and bar shape due to changes in speed and changes in the solution is precipitated Agency. Travertine due to its high porosity property is suitable for indoor and outdoor shots. Travertine can be very cold even in areas with high rainfall but also a stone facade work without worrying about it.
