Cast Brass.
Оглавление—The various articles of bronze, so called, statuettes, clock cases, etc., made in France, where this industry has attained great perfection and extensive proportions, are not, in many cases, genuine bronze, but fine cast brass. Following are the compositions of a few mixtures of metals most frequently used by French manufacturers:
Copper | Zinc | Tin | Lead | |
---|---|---|---|---|
I | 63.70 | 33.55 | 2.50 | 0.25 |
II | 64.45 | 32.44 | 0.25 | 2.86 |
III | 70.90 | 24.05 | 2.00 | 3.05 |
IV | 72.43 | 22.75 | 1.87 | 2.95 |

Their special advantage is that they can be readily cast, worked with file and chisel, and easily gilded.
