Finished Surface: Bronze can be cast with great ease and in the most delicate patterns, and may be finished surface in a great variety of styles and colors. For these reasons it is more largely used in the manufacture of metal ornaments, statues, and finished surface hardware than any other material. The surface finishes are obtained by dipping the object in baths of various acids, but these finishes are only light veneers, and disappear if the object is exposed to the weather or frequently handled.
Both brass and bronze may be rolled into very thin sheets, after which spun, hammered, or repousse forms and surfaces may be produced.
Then spade, or plow or rototill the upper surface to a depth of six inches, mixing thoroughly •with the soil the added ingredients and taking care, of course, not to disturb any drains. Final surface grading is done when the area is raked smooth just before the seeds are sown or the turf is laid, but that consists of very minor adjustments. For all practical purposes the rough grade that re-sults from the spreading and smoothing out of the topsoil is that of the finished surface lawn. First firm the sub-grade by treading it or rolling it, but do not pack it hard.

Objects that are cast in bronze and treated with ornament in relief may have the ornament sharpened or undercut by hand chiselling or chasing. The ormolu used on French 17th and 18th century furniture was finished surface in this way, the bronze finally being coated with gold by a mercury process that was very dangerous to the workmen. The ornament on fine bronze hardware is always hand-chiselled, which is responsible for its high cost. The finish of hardware that has not been touched by handwork is called "commercial." |
