Travertine rocks have a good resistance to cold, heat, UV rays and air humidity compared to other rocks. Of course, most granites also have these properties, but sometimes air humidity may oxidize the iron minerals present in ... Read More
What is Marble?
Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. It is composed primarily of the mineral calcite (CaCO3) and usually contains other minerals, such as clay minerals, micas, quartz, pyrite, iron oxides, and graphite. Under the conditions of metamorphism, the calcite in the limestone recrystallizes to form ... Read More

Ma rble stone is a type of limestone that has undergone a high temperature and high pressure exchange. In this transformation, fine-calcite crystals crystallize and converge into coarse crystals. The veins in the marble rock are related to impurities in the primary limestone.
