Tezontle
Tezontle (Spanish: tezontle) is a porous, highly oxidized, volcanic rock used extensively in construction in Mexico. It is usually reddish in color due to iron oxide.[1] Tezontle is a well-cemented, agglomeritic and scoriaceous rock.[2]
Uses
Tezontle can be mixed with concrete to form lightweight concrete blocks,[3] or mixed with cement to create stucco finishes.[1] Tezontle is often used as the top layer of gravel on unpaved roads in Mexico. Many colonial buildings in Mexico use the reddish cut tezontle on their facades.
Facades
Many buildings use tezontle to create an aesthetic facade. Here are some examples.
- Church of San Bernardo, Mexico City
- House of Count de la Torre de Cossio
- Mexico City Metropolitan Cathedral
- Nacional Monte de Piedad
- National Palace (Mexico)
