Tile. Colored tiles form a very effective (34) Flat reinforcing bars were bent into parabolas to follow the lines of maximum tensile stresses in the early days of reinforced concrete, according to W. W. Clifford ("The Architectural Forum", May 1922, p. 178). surface decoration (Fig. Ill, 141). The thinner tiles are usually placed before pouring--for ceilings directly on the forms, and for vertical surfaces glued to paper or to canvas or set in forms with clay. Tile is also laid in precast concrete slabs which are set into recesses created by the formwork. O. C. Hering states that when unglazed tiles are used their backs should be soaked in water and their face oiled as protection against efflorescence--an unnecessary precaution with glazed tile. A piece of felt placed on the face of the tile also protects from surface staining by wet concrete. The back of a tile should never be oiled as it would lose its porosity and power of adhesion.
