2. Forming method: according to the size of the bronze cross section, cut off similar copper pieces, after heating, use the ductility and plasticity of copper to beat the shape of the original device with a long hammer with a special shape, and then make up the broken bronze.
3. Casting method: Taking the intact part of the bronze ware itself as a model, the molding sand or clay is made into an outer mold, and the metal fittings with damaged parts are cast, and then the damaged bronze ware is replenished.
4. Pattern carving method: According to the sketched patterns (gluttonous patterns, kuiwen patterns, thunder patterns, etc.), hammer carving with various self-made chisels. ), compared with the original pattern, repeatedly carved and filed until the pattern is as fine as the original pattern.
5. Carving and inlaying method of patterns: draw the original patterns on the fittings, carve (cut) them into grooves with a suitable chisel, and then embed inlaid metals (copper, gold, silver and other thin sheets or wires) into the grooves with a special chisel under pressure and file them flat.
6, bronzing, hot gold and silver method: commonly known as "hot gold and silver." Heat with mercury to melt gold and silver respectively to make gold paste (gold amalgam) or silver paste (silver amalgam), then wash the bronze fittings with acid solution, then apply the gold paste or silver paste evenly on the fittings, heat with charcoal fire to evaporate mercury, then immerse the plated part in the water of soapstone, brush the luster of gold or silver evenly with copper wire brush, and finally roll it with agate.
7. False rust method: Pigments and various powder-type water-insoluble pigments are mixed into various paint pastes and mud, and according to the corrosion phenomenon of bronzes themselves, two types of "ground" and "rust" with the same image are made to cover up the traces of bronze restoration.
8. Rust removal method: Use acidic or alkaline substances to act on bronzes. After the bronze rust scale is dissolved or relaxed, remove it and restore bronze patterns or inscriptions.
Extended data
When the bronze ware is deformed as a whole, different tools and fixtures can be used according to the deformation degree and different parts, and methods such as propping, jacking, prying and twisting can be used to correct it. No matter what method is used, it depends on the stress change and bearing capacity of cultural relics. Generally speaking, according to experience and understanding of cultural relics, the ability is correct.
Bronze cultural relics are mostly cast, and after long-term corrosion, their ductility and elasticity are reduced to some extent. Therefore, for severely deformed objects, only sawing and assembly welding can achieve the final goal of shaping.
