separately. First of all, they make a skeleton according to its design, and make original clay mold. After that, they apply plaster mold and silicone mold to duplicate a wax pattern. The following part is using sanding-casting and lost-waxing to fabricate. And the top part of the sculpture – birds are built by forging small corrosion resistant plate. After every part of the sculpture is casted, they are loaded to the site to install.
After the statue was designed, the workers fabricate the statue part by part. The statue is too huge to make as a whole, so that each of it should be fabricated separately. After the upper part and the lower part of the body are respectively finished, they are loaded and transited to the site.
He spent several weeks learning the heroic deeds of Yang Zirong and thinking about his modeling, so that the sculpture can embody the hero’s image exactly. He made a small one 1: 6 as a model and the sculptors can build the sculpture to scale.
Step Two: Making Clay Framework
Step Six: Bronze Casting
Bronze casting was the most important part to fabricate the large sculpture. In this step, both sand-casting and lost-wax casting are applied. Under high temperature of 1400 degrees, the wax pattern lost and the bronze sculpture appeared.
Step Eight: Patina
After the sculpture was installed, the last step is doing patina on bronze. Before doing it, it is necessary to ensure the sculpture was clean and free of oil and grease by scrubbing it with a weak "pickle" solution of nitric acid. The craftsmen sand blast the bronze, and a couple coats of ferric
