A Look Inside a Marble Factory
We're reporting from Almeria, a province in southwestern Spain where surfaces company Cosentino
is headquartered. For the past couple of days, we've gotten a first-hand look at how the company manufactures its products—natural stone and engineered surfaces Silestone and the just-announced Dekton. Here we share the journey of a natural marble slab from mountaintop to manufacturing.
Our journey starts millions of years ago, before Spain and Europe as we know it existed. This land used to be submerged deep underwater. Over time, minerals and salts were transformed into sedimentary rock. Travertine, limestone, and marble descend from the same components and represent various phases of calcification. On the top, travertine is the most porous and pitted. Dig a little deeper and you'll find limestone. Deeper still, is marble, which is the most prized and valuable. It takes about 250 million years to form marble.
