First of all, prepare the clay for processing sculptures. Soft and hard clay should be used appropriately, and it is best not to stick to the hands; if the clay is too wet, it should be placed in a ventilated place to dry it to the proper humidity. If it is too dry, disassemble it and put it in a container. It should be immersed in a sufficient amount of water, then tamped, and then put the processed mud into a jar or other container, and cover it with a damp cloth or plastic to maintain humidity for later use.
Then, the general level is 12289; sample production (1) according to the determined design drawings; (2) under the condition of respecting the original manuscript, the small sample production fully considers the main body's comprehensive influence, processing feasibility, structural rationality and craftsmanship. Then recreate 3.2289 from the three-dimensional structure and artistic modeling; the internal frame is usually made of wooden squares, planks, steel wires, steel nails, etc. Clay sculpture bones, like human or animal bones, play the role of support and connection. This is the basic condition of clay sculpture, the precautions when constructing the skeleton: (1) The frame should be strong to ensure the stability of the clay sculpture, and it will not tilt or collapse when filling with mud. (2) After accumulation of mud, the mud cannot fall and the frame cannot be exposed. (3) Reflect the overall shape of the sculpture. (4) The frame should be simple when making molds and easy to replace and disassemble.
After preparing the mud and the skeleton on a large scale, you can start loading the mud. Spray water on the skeleton so that the mud can be firmly attached to the skeleton and will not fall easily; when the mud is loaded, the mud blocks are layered layer by layer Place the ground on the skeleton, squeeze it by hand, then add the mud layer by layer, then use a wooden hammer or clap your hands to break the mud and stick it tightly. We should focus on the overall outline and start again. We should not be too timid to influence local details. Sculpture is a three-dimensional unit. Each time you add mud, you must consider the relationship between different perspectives. The sculpture platform should be rotated frequently for observation and comparison. As long as the mud is large, it should not be collected at once.
In deep casting, according to the exact large size and proportion, you can enter the deep casting stage. With the deepening of the parts and details, the volume of the clay sculpture is gradually in place. We should always compare this part with the whole to make this part subordinate In the process of in-depth molding of the whole, we should constantly adapt and understand the relationship between parts and parts, and deal with the relationship between parts and parts. We should also think twice before acting and always firmly grasp the principle of "whole". As long as you have a good grasp of the whole, you can complete the part correctly, and complete the part accurately, which can enrich and perfect the entire range. In addition, pay attention to the symmetry relationship. A center line can be drawn on the clay sculpture for inspection, comparison and correction.
In the deepening stage of adjustment and unification, it is inevitable that certain local details will become too obvious, the major turning points of the body will be weakened, and there is a lack of consistency or rigid behavior between forms. In the stage of adaptation and unification, it is necessary to adjust it to the overall relationship. In order to maintain the moisture content of the clay sculpture, pay attention to spraying water during the molding process; if the temperature is low in winter, if the clay sculpture does not keep warm, the whole sculpture clay will crack when it freezes, so Need to work in a warm room. After each work is completed, plastic cloth is used to wrap the clay so that it is not easy to dry and crack, and moisture is not easy to volatilize, so as to continue molding.
In the process of turning the external mold, the clay is divided into two parts, and then an insulating layer is applied; the mold separation should fully consider the comprehensive influence of the main body, the feasibility of processing, the rationality of the structure and the artistry of the craft, and the three-dimensional structure and art The mold is separated in the shape. When the plaster shape is turned over, it is necessary to reinforce with the appropriate length of wood to control the large-scale.
Coat the back of the plaster mold with a thin layer of unsaturated polyester resin, then spread two layers of glass fiber cloth, and pre-woven with glass fiber3. Finally, a layer of unsaturated polyester resin is applied to form the product.
