How to Make Spanish Tile Roofing

Round one side of a 4-by-4 beam to the desired curve of your Spanish tiles by sawing two corners down at a slight angle and sanding the surface smooth. This will be the mold for your tiles, traditionally known as a "burro."

Mix dry bonding clay with water, adding clay powder until it will no longer absorb moisture. Allow the mixture to sit for 24 hours.

Drain off any water remaining on top of the clay. Spread the clay in the sun to dry until no longer sticky.

Take a clump of clay and strike it repeatedly against a hard surface. This process, known as "wedging," removes air bubbles that can weaken the tile when fired.

Place globs of wedged clay on the burro and roll them out flat with a rolling pin. Cover the entire burro with an even layer of clay. Score the clay at even intervals along the burro's length to divide the tiles from each other.

Allow the tiles to dry on the burro for 24 hours. Remove the tiles and place them in your fireplace or fire pit. Build a fire on top of the tiles and keep it burning all day. Remove the fired tiles the next morning.
