Burnt Adobe is at home in Tucson
Tucson is said to have the most burnt adobe homes in the United States. Lucky us! Most of these homes were built between 1950 and 1970. Burnt adobe was used in many styles of homes including Ranch, Midcentury Modern, Territorial, and Spanish Revival style homes. Burnt adobe homes are easily recognizable in their natural state, although sometimes they’ll be mortar-washed, painted, or stuccoed over the years. It’s a real treat to see burnt adobe home interiors and exteriors with the adobe left natural, without an opaque paint or plaster coating.
What is burnt adobe?
If you’re new to Tucson or Southern Arizona, you may not have heard of burnt adobe before. It’s a regional material made in the northern part of Sonora, Mexico that gained popularity during the post WWII building boom. But once you’re familiar with the material, you’ll see it almost everywhere in Tucson.
Burnt adobe, which is different than mud adobe, is made of mud and clay that is formed into bricks then fired in ovens. They are much larger and thicker than red bricks and are easy to spot. The exterior of the burnt adobe blocks have a hard shell which needs to be protected from water by using a sealant that needs to be reapplied periodically. Burnt adobe is made in the northern part of Mexico, which is one of the reasons it is such a popular material in Tucson. It isn’t used much farther north than Tucson, due the prohibitive cost of shipping.
Types of burnt adobe
There are 3 types of burnt adobe: Sasabe, Querobabi, and San Luis. The first 2 are named for the towns where the adobes are made. Most burnt adobe homes in Tucson use the Sasabe adobes, probably because the town of Sasabe is closer to Tucson than Querobabi. Sasabe adobe is more orange while the Querobabi adobe is more red, and the San Luis adobe is multicolored with hints of yellow, black, orange, red, and brown. San Luis adobe is striking in appearance, but was rarely used in Tucson.
