Cantera Roja: complete guide
Cantera Roja is a red Mexican volcanic stone, lightweight and easy to carve. It is chosen to bring warmth and character to façades, columns, fireplaces and decoration.
History and origin
In Mexico, the name cantera refers to the volcanic tuffs used for centuries in architecture, particularly in the colonial buildings of many of the country's cities. Its workability made possible richly carved portals, columns and façades. Today it is also widely used in furnishings and interior decoration. Marmi di Carrara supplies it on request.
Look and veining
The background is red or reddish brown, with a fine grain and small lighter or darker inclusions typical of volcanic rocks. The appearance is matt and textured, with variations in tone from one block to another. It is usually finished matt honed, brushed or carved; it does not take a mirror polish.

FAQ
What exactly is cantera?
It is a volcanic tuff formed from consolidated ash: lightweight, porous and easy to work, very different from marbles and granites.
Can it be used outdoors in cold climates?
With caution: its porosity makes it sensitive to frost. In areas with harsh winters it is best used in sheltered positions and well protected.
Is it suitable for fireplaces and fountains?
Yes, these are among its most typical uses; fountains require a water-repellent treatment and regular maintenance.
