Step 1: make small clay sculptures 

step 2: cover the sculpture with large clay. 

Step 3: make the clay sculpture prototype

step 4: complete the large-scale sculpture, and inform party a to review and put forward opinions or modifications on the large-scale sculpture. 

Step 5: in the turning stage, the clay model is divided into sections for the block mold design, and then the soap water is sprayed as the isolation protection.

Step 6: remove the residual mud from the block mold after demoulding, and fine repair and grinding the plaster mold after completion. They are then sanded with copper mesh. Step 7: casting (a process with the hollow ceramic shell are placed in sintering furnace according to the different alloy at 1000 ℃ to 1150 ℃ sintering, will be immediately cast copper liquid into the ceramic shell, after cooling will be broken by the outer ceramic shell, stripping out of copper products is thick body) step 8: product casting shaping and processing (for casting of copper products sandblasting and clean, and cutting, grinding, heat treatment, plastic, machining, polishing and processing) step 9: Surface effect treatment and protection (for copper casting surface treatment, there are usually cold coloring and hot coloring, specific coloring and characteristics, we will introduce to you one by one in future articles, and finally do waxing protection and polishing)
