[From the Brickbuilder.]
Figs. 127 and 128 are suggestions for moulded brick cornices for three and four-story buildings, and Fig. 129 one of plain bricks for a two-story building with a low pitch roof. Fig. 130 shows a section of a simple brick cornice that the author has used on brick churches having a pitch roof.
Decorative brickwork should always be executed in smooth, regular brick of even color, as uneven colors and rough brick mar the effect of light and shade and detract from the design.
For brick cornices a copper or galvanized iron crown mould, such as is shown in Figs. 127 and 129, is very appropriate. The metal should be carried over the top of the wall (if a parapet) and down 5 inches at the back.'
If the wall terminates as shown in Fig. 128 the upper courses should be laid in cement mortar and the top well plastered with Portland cement. This will protect the wall for several years, but is not as lasting as terra cotta or metal.
Surface patterns, or diaper work, are very common in brick buildings in Europe, and they have lately been introduced to a considerable extent in this country.
Their chief object is to give variety to a plain waft space. When used in exterior walls they should not be so marked as to make the pattern insistent and thus interfere with other features of the building.
Usually sorting the brick into light and dark shades, or varying the color of the mortar in which the pattern is laid, will be sufficient for any surface decoration, the best success in this class of decoration being obtained by using comparatively simple designs and quiet contrasts of color.
If different colors are used the greatest care must be exercised in their selection, and even with care and thought it is not granted to all architects to use color nicely.
One of the best opportunities for the use of color lies in the direction of pattern work for frieze and band courses.
Surface patterns should generally be flush with the wall. When used as in Fig. 133 the pattern may project ¼ inch from the surface or panels.
Diaper work may also be used with good effect on interior brick walls of waiting rooms, corridors, public baths, etc.
