Kiln-baked brick appeart in the reign of Augustus (r. 27 B.C.-14 A.D.), long;: and narrower than ours and used both for facir.: concrete blocks and independently. For their monuments. buildings, the Romans turned to concrete blocks; pozzno-lana, a volcanic ash, provided a natural cement. Regular ashlar masonry, opus quadratum, needed no facing, but the Romans believed that concrete blocks did. Opus incertum, perhaps the earliest type, consisted of irregular blocks embedded in the surface. Opus reticulatum, square blocks arranged t diamond pattern, was standard under the empire through the reign of Hadrian. In later times, alternate hands of stone and brick, opus mixtum, iormecl the facing.

Decorators are often confronted with rooms that have walls in part or entirely of masonry that cannot easily be changed. These walls may consist of cut or uncut field stone, ashlar, concrete blocks or cement-blocks, brick, or various types of tile. Stone is often used for fireplaces and chimney-breasts and it is best in these cases to leave the stonework in its natural finish. concrete blocks or cement-blocks, if used structurally, usually form walls that are 8 or 16 inches thick, and as these materials are moisture-absorbent in the majority of climates, they require a furred interior finish Wall of plaster or other material, built with an air space between it and the blocks. In warm and dry climates, or where walls are well protected by a Roof overhang, block walls may be treated with either a water or oil paint. Bricks and tiles are produced in an infinite variety of colors, textures, and sizes, and there is no objection to using them in their natural finish, if they are of good quality and color; otherwise a coat of paint is preferable. Masonry materials have a degree of permanence that does not exist in the majority of Wall surface treatments, and they have the added advantage of low cost of upkeep.
