| A process for finally finishing a surface of a | | | | then used in a lost wax casting procedure to |

| single wax coating. In a practice of the invention, | | | | original clay. This procedure has, of course, been |
| to a bronze surface that has been polished and | | | | long known, and such castings are found even in |
| preliminarily buffed, a low pressure grit material | | | | very early civilizations. In fact, in many respects |
| flow is directed against a section of the bronze | | | | such earlier bronze castings are not much |
| surface as a final surface texturing step and, | | | | different from those as are produced today. Nor, |
| where a surface or surfaces adjacent to the | | | | in fact, are the finishes and the finishing processes |

| flexible surface that adheres to so as to | | | | thereof, and application of finishes, such as |
| essentially render the bronze surface imperious to | | | | patinas, and final waxing, are similar to processes |

| application of paint, patina, or the like, the plastic | | | | use, such as power grinders, sand blasters, and |
| material coating is stripped away by a painter | | | | the like, have made the performance of steps in |
| operator using a tool or tools, such as a pair of | | | | such polishing of a bronze surface to smooth it, |
| tweezers, to remove the coating. Whereafter the | | | | and buffing of the smooth surface, much easier, |
| sculpture surface is waxed. | | | | the steps themselves and purposes of each are |
| Bronze statue as works of art are often first | | | | essentially the same. Also, such processes have |
| formed in clay, or other material, wherearound a | | | | further included an application of a coating or |
| mold is formed to receive hot wax poured | | | | coatings of wax to the buffed surface to |
| therein to form a wax casting. The wax casting is | | | | preserve that finish. |
