To confidently specify brick, consider color, texture, size, shape, type, grade, availability, and absorption characteristics. COLOR Colored brick are produced in several ways: through-the-body brick; clay-coated brick; and glazed brick. TEXTURE Texture is another determinant of brick appearance. Brick texture can be smooth, scored, wire-cut (velour), paper-cut, stippled, or bark, to name a few. Most brick are made in one of two basic ways: extruded or molded. SIZE AND SHAPE Today, the number of brick sizes readily available has increased dramatically. In addition to special sizes, special brick shapes also are available to meet specific structural and aesthetic needs. FIELD PANELS A field panel typically is constructed as a free-standing sample (torn down when the project is complete) containing the equivalent of 100 standard-size brick and constructed from the same production run intended for shipment to the project. TYPES OF FACING BRICK ASTM C 216 identifies three types of facing brick: Type FBS; Type FBX; and Type FBA. GRADES OF FACING BRICK ASTM C 216 recognizes two grades of facing brick: Grade SW (severe weathering); and Grade MW (moderate weathering). ABSORPTION There are two types of absorption: saturation and initial rate absorption (IRA). Both are important in specifying brick.
