What is the production process of stone crafts?

stone art is something we often see in our daily life, so have you ever seen stone crafts? stone crafts are an important part of stone art culture and art. stone crafts have a long history and mature technology. The craftsmanship of stone crafts is more complicated than wrought copper, and the restoration of artistic creation is better. Therefore, it is suitable as a material for fine works and is very popular among artists, especially stone art of figures is very common. But it is easy to oxidize, so pay more attention to maintenance.

The craftsmanship of stone crafts has a history of thousands of years. To complete an exquisite chiseled handicraft requires more than ten technological processes, coupled with the creation of skilled workers, and the ingenuity to create individuality and create a modern stone art work. stone crafts are not general and simple crafts, but stone art casted through professional molds and techniques and other multi-faceted grinding. It is made of stone crafts materials.
1. stone art modeling design, first of all, is to conceive the overall stone art, design the drawing sample, and then cast the stone crafts according to the pattern.
2. Clay draft production, according to the size of the design draft, build the skeleton, mold it with mud, and make a rough model with the clay draft according to the pattern, which is convenient for shaping. The specific details and requirements can be carefully depicted on the clay sculpture. This process The degree of realization and the overall effect should be considered.
3. There are three kinds of molds: one is to use plaster if it is not too complicated; the other is to use glass fiber reinforced plastic to make molds. Which mold to use can be determined according to the specific situation, because the process and cost of each mold are not used, and the most important thing is the cost.
4. Pouring paraffin. After the mold is turned over, pour the melted paraffin into the plaster mold or silicone mold that has been made. After the paraffin cools and solidifies, it becomes a wax model.
5. Shell making, there are two types of shell making: one is small or complex, we should choose precision casting, the so-called precision production is to use fine quartz sand to wrap the wax pattern layer by layer, and then Use high heat to burn off the paraffin inside the shell. The other is resin sand box production. Sand box production is generally suitable for simple, flat reliefs, large copper coins, the back of copper Buddha statues, and other smooth surfaces without much craftsmanship.
6. Casting, the copper is melted into copper water at high temperature and poured into the finished shell or sand box.
7. Grinding, cleaning riser grinding.
8. Stitching, put the polished stone art together to form a complete whole.
9. Clean up the welding joints and process the welded parts of the spliced stone art, so as to be closer to the design and production process requirements.
10. Color processing, according to the customer's requirements or the specific situation of the design sample, because the colors of different periods are different, the ancient ones are generally suitable for bronze, and the modern ones are generally suitable for bronze, and there are many modern ones. Gold, gilded, and painted.
11. Oiling and sealing wax, oiling and sealing wax can make our stone crafts last for a long time.
