The varieties of marble colours are generated by the impurities contained (red from the iron salts; brown from manganese salts, grey from graphite, etc.), while its veins are caused by the numerous cracks filled with secondary calcite.

Thanks to its characteristics, marble is highly recommended for indoor work: floor and wall tiling, frames, stairs, decorative elements, etc. For outdoor work, marble should be subject to special treatment as it is affected by the weather, which may lead to it becoming matte or cracking as a result of the freeze-thaw cycle or acid rain. It is recommended for low- and medium-traffic floors and stairs given its average wear coefficient.
Marble has been one of the most popular materials since antiquity due to its multiple colour varieties and versatility. There is a wide range of marble varieties, which cover a very large geographical area of origin: Italy, Greece, Spain, Turkey, Romania, Portugal and Brazil.
