Brick
Solid brickwork is made of two or more layers of bricks with the units running horizontally (called stretcher bricks) bound together with bricks running transverse to the wall (called "header" bricks). Each row of bricks is known as a course. The pattern of headers and stretchers employed gives rise to different bonds such as the common bond (with every sixth course composed of headers), the English bond, and the Flemish bond (with alternating stretcher and header bricks present on every course). Bonds can differ in strength and in insulating ability. Vertically staggered bonds tend to be somewhat stronger and less prone to major cracking than a non-staggered bond.

Famous quotes containing the word brick:
“Follow the yellow brick road.”
—E.Y. Harburg (1898–1981)
“Sometimes among our more sophisticated, self-styled intellectuals—and I say self-styled advisedly; the real intellectual I am not sure would ever feel this way—some of them are more concerned with appearance than they are with achievement. They are more concerned with style then they are with mortar, brick and concrete. They are more concerned with trivia and the superficial than they are with the things that have really built America.”
—Lyndon Baines Johnson (1908–1973)
“Protoplasm, simple or nucleated, is the formal basis of all life. It is the clay of the potter: which, bake it and paint it as he will, remains clay, separated by artifice, and not by nature from the commonest brick or sun-dried clod.”
—Thomas Henry Huxley (1825–1895)
