Many clients are interested in our metal Outdoor Sculptureswhich are popular for their delicacy in details and metal attributes. Here we share the basic knowledge for your reference.  Firstly, the specification of materials. Brass is made of sixty percent copper and thirty percent of zinc, as well as ten perfect of iron and lead. While bronze is made of eighty five perfect of copper, and ten percent of zinc, five percent of tin, five percent of lead and zinc.

     The copper itself is not mobile, and it can not be poured in the sand shell and the wax shell. The addition of zinc and tin added to the copper component can enhance the fluidity of the copper water and facilitate the casting. In the copper composition, it is necessary to add a corresponding proportion of zinc. Zinc can enhance the hardness of copper. Otherwise, the copper will be as soft as a copper wire, and the wire cannot be formed.

     Surface color is the life of bronze Bronze Sculptures (lost wax).  Long time exposure in outdoor environment may let the bronze sculptures lose their former colors under the influence of oxidation or acid rain. So the post-maintenance work of bronze sculpture has become the focus. So how do you keep the bronze sculptures in their original colors? Most people use high-pressure water to wash the above problems. This kind of palliative treatment is a kind of harm to the bronze sculpture itself. If the dirt on the bronze statue is too heavy, first blow it with a cold wind air blower. Then use a straw brush to clean, and finally use a soft brush to finish. Never use metal polish, water, or any other solvent. That will make the bronzes fade. Finally, a layer of colorless wax on the copper sculpture can make the copper body anti-oxidation, anti-corrosion, acid rain and air pollution, and directly make the original color of the bronze sculpture still. This bronze sculpture restored its former style.
