Everyone who is anyone in Saltillo makes clay floor tiles from the abundance of raw material that is at hand. Wood drying racks are strewn across yards, front and back, which are connected by well-worn paths to nearby clay pits. Unlike most other floor tiles, Saltillo tiles are not baked in a high-temperature kiln. The tiles are, therefore, extremely soft and crumble easily. They are not tough at all, but they are extremely cheap to buy.
Saltillo tiles impart a rustic look that no other material can match.
People who like Saltillo tiles love them, and those who don't, hate them. There doesn't seem to be much middle ground. In my neck of the woods, the states bordering on Mexico, Saltillo tiles have been common for years. They have also made their way up north during the past couple of decades. Although Saltillo tiles are inexpensive to buy, an installation might end up costing you more than one using ceramic tiles due to increased labor costs.
