This Japanese tall antique patinated copperware censer is made in low relief about 100 years ago. It was made by the Copper Lost Wax Cast Method. A four-paneled censer sits on tall legs and a stand adorned by a shishi lion finial lid. While worn with age the figures can still be seen in low relief on each panel. One one panel a shishi lion rises above a row of waves and modified by a vine of flowers. On the other side are wrestling foo dogs. Stylized crabs above the waves are also seen. the color is beautiful and the piece has nice patina. The tall lanky legs curve inward. Two most unusual handles are on either side of the lid decorated with scrolling flowers, representing what appears to be the motif of prickly vines from the roses perhaps. Four small holes in the top allow the smoke to escape. The censer is in very good condition, with no dings missing parts or repairs. There is age wear ro the surface which has developed nice patina.

the Copper Lost Wax Cast Method
Techniques of the main cast Casting a metal which is melted and poured into a prototype which had been made beforehand, it is metalworking method for the form of interest. Although the basic technology of casting was born thousands of years ago has not changed even now, and if there is a variation of a number, you cannot use the four main techniques in Takaoka copperware. By the respective techniques, also different prototype development
Wax casting method This is the most high-precision technique. Beeswax to create a prototype in which the combined boiled pine resin extracted from the hive and Japan wax extracted from the fruit of goby and baked at high temperature wrapped in soil, a prototype of the wax is melted by the heat, the gap is born . And pouring the metal to be dissolved here.
Lost Wax Method A molten metal is poured into a mold that has been created by means of a wax model. Once the mold is made, the wax model is melted and drained away. A hollow core can be effected by the introduction of a heat-proof core that prevents the molten metal from totally filling the mold. The lost-wax method dates from the 3rd-millennium bc and has sustained few changes since then. To cast a clay model in bronze, a mold is made from the model, and the inside of this negative mold is brushed with melted wax to the desired thickness of the final bronze. After removal of the mold, the resultant wax shell is filled with a heat-resistant mixture. Wax tubes, which provide ducts for pouring bronze during casting and vents for the noxious gases produced in the process, are fitted to the outside of the wax shell, which may be modeled or adjusted by the artist. Metal pins are hammered through the shell into the core to secure it. Next, the prepared wax shell is completely covered in layers of heat-resistant plaster, and the whole is inverted and placed in an oven. During heating, the plaster dries and the wax runs out through the ducts created by the wax tubes. The plaster mold is then packed in sand, and molten bronze is poured through the ducts, filling the space left by the wax. When cool, the outer plaster and core are removed, and the bronze may receive finishing touches.
