Brick made for general building purposes and not specially treated for color and texture. Also called building brick.

Brick made of special clays for facing a wall, often treated to produce the desired color and surface texture.

A designation indicating the permissible variation in size, color, chippage, and distortion allowed in a facing brick unit

A designation indicating the durability of a brick unit when exposed to weathering

The weight of water absorbed by a clay masonry unit when immersed in either cold or boiling water for a stated length of time, expressed as a percentage of the weight of the dry unit

The ratio of the weight of water absorbed by a clay masonry unit immersed in cold water to the weight absorbed when immersed in boiling water, indicating the probable resistance of the brick to the action of freezing and thawing

The weight of water absorbed by a clay masonry unit when partially immersed for one minute, expressed in grams or ounces per minutes. Also called initial rate of absorption.

A white, powdery deposit that forms on an exposed masonry or concrete surface, caused by the leeching and crystallization of soluble salts from within the material

The process of forming brick by molding relatively wet clay having a moisture content of 20% to 30%

The process of forming brick and structural tile by extruding stiff but plastic clay having a moisture content of 12% to 15% through a die and cutting the extrusion to length with wires before firing

The process of forming brick by molding relatively dry clay having a moisture content of 5% to 7% under high pressure, resulting in sharp-edged, smooth-surfaced bricks

Brick formed in the soft-mud process with a mold lined with sand to prevent sticking, producing a matte-textured surface

Brick formed in the soft-mud process with a mold lubricated with water to prevent sticking, producing a smooth, dense surface

A brick made of fire clay and used for lining furnaces and fireplaces

A dense, hard-burned brick used esp. for paving

A furnace or oven for burning, baking, or drying something, esp. one for firing pottery, baking bricks, or drying timber

Firing brick units alternately with too much or too little air to vary their face color

A brick or timber rejected as being of inferior quality

A refractory clay used in the making of firebricks, crucibles, and other objects exposed to high temperatures

A material having the ability to retain its physical shape and chemical identity when subjected to high temperatures

A brick or tile having normal face dimensions but a nominal thickness of 2 in. (51 mm)

A brick cut transversely so as to leave one end whole

To chip or rub stones or bricks to a certain size or shape

A brick or other masonry unit laid horizontally in a wall with the longer edge exposed or parallel to the surface

A brick or other masonry unit laid horizontally in a wall with the shorter end exposed or parallel to the surface

A brick laid horizontally on the longer edge with the shorter end exposed. Also, rollock.

A brick laid vertically with the longer face edge exposed

A brick laid vertically with the broad edge exposed

A brick laid horizontally on the longer edge with the broad face exposed. Also called bull stretcher.

Brick construction, esp. the art of bonding bricks effectively

Any of various arrangements of a masonry units having a regular, recognizable, usually overlapping pattern to increase the strength and enhance the appearance of the construction

A masonry unit specially formed or cut to finish a course or complete the bond at the corner of the wall. Also, closure.

A continuous course of headers or bondstones overlapping more than one wythe of masonry

A brick of half the normal width, used for completing a course or for spacing regular bricks

A three-quarter brick for finishing a course or for spacing regular bricks

A brick having a darker end exposed as a header in patterned brickwork

A brickwork or masonry bond composed of overlapping stretchers. Also called stretcher bond.

A brickwork or masonry bond having successive courses of stretchers with all head joints aligned vertically

A brickwork bond having a course of headers between every five or six courses of stretchers. Also called American bond.

A continuous course of headers or bondstones overlapping more than one wythe of masonry

A continuous course of stretchers in brickwork

A continuous course of headers in brickwork

A brickwork bond having alternate courses of headers and stretchers in which the headers are centered on stretchers and the joints between stretchers line up vertically in all courses

A modified English bond in which the head joints in the stretching courses are offset by half the length of a stretcher. Also called Dutch bond.

A brickwork bond for lightly loaded boundary walls, having a sequence of a header and three stretchers in each course, with each header being centered over a header in alternate courses

A brickwork bond having alternating headers and stretchers in each course, each header being centered above and below a stretcher

A modified Flemish bond having courses of alternate headers and stretchers alternating with stretching courses

A form of Flemish bond cross bond in which the courses are offset to form a diamond pattern
