"Brick compares favorably with stone as a structural material for its fire-and-weather resisting qualities and for the ease of production, transportation, and laying."
 * a. Comparison and contrast**

"Bricks may be used in construction only in conjunction with mortar, since the unit is too small, too light, and too irregular to be stabilized by weight." **
 * b. Description

<span style="font-family: Georgia, serif; color: rgb(162, 21, 79);"> "Special shapes can be produced by molding to meet particular structural or expressive requirements (for example, wedge-shaped bricks are sometimes employed in arch construction and bricks with rounded faces in columns)." ** " <span style="color: rgb(162, 21, 79); font-family: Georgia; font-weight: normal;">The commonest ancient Roman bricks were cut into triangles and laid with the base out and the apex set into a concrete filling that provided additional strength." **  <span style="font-family: Georgia, serif; color: rgb(162, 21, 79);"> "Brick which has been used since the 4th millennium BC, was the chief building material in the ancient Near East. The versatility of the medium was expanded in ancient Rome by improvements in the manufacture of both brick and mortar and by new techniques of laying and bonding. Employed throughout the Middle Ages, brick grained greater popularity from the 16th. Century on, particularly in northern Europe. It is widely used in the 20th Century, often for nonbearing walls in steel frame constructions."
