1. Main material. Campus stone sculpture, like all campus material landscapes, accumulate historical, traditional, cultural and social values, and contain huge potential educational significance. By being interpreted, the campus stone sculptures not only enable students to grasp the environmental perception of a certain group, but also understand the design ideas, attitudes, emotions and values of a specific culture from the stone sculpture works are subtly affected.
The most commonly used and cheapest main material for
stone carving is mud, which is also the closest to stone sculptors. It has the advantages of strong plasticity, easy modification, small preservation difficulty, wide range of temperature adaptability, and low cost. The prototype is made of mud, but not all mud can be used for stone carving. Campus stone sculpture, like all campus material landscapes, accumulate historical, traditional, cultural and social values, and contain huge potential educational significance. By being interpreted, the campus stone sculptures not only enable students to grasp the environmental perception of a certain group, but also understand the design ideas, attitudes, emotions and values of a specific culture from the stone sculpture works are subtly affected.
It must be clay with strong cohesiveness and fine texture. At present, the commonly used clay in our country includes: yellow clay, which is produced in hilly land, with fine soil quality and strong viscosity, and green gray soil, which is produced in the Jiangnan area of our country and has stronger adhesion than yellow clay. , and the soil is fine, soil red mud, fine soil, good viscosity, small shrinkage, is the ideal soil for stone carving, pottery clay, uniform particles, strong viscosity, fine soil, but large shrinkage, these muds should be stirred several times before use , its use effect will be better. In addition to using mud for stone sculpture, there are also materials such as oil mud, flour, and sugar for stone sculpture. Flour and sugar are used more among the people, and oil mud is often used by stone carvers. Oil mud is A synthetic material manufactured artificially. It is melted from waste rubber, wax, vegetable oil or engine oil, talcum powder and other materials. It has strong viscosity and is not easy to dry and crack. Generally, stone sculptors often use it to make small manuscripts or works of smaller size.
2. Stainless steel stone carving accessories.
There are many auxiliary materials for stone carving, and they are mainly to strengthen the strength of stone carving. These materials include wood, metal, silk and hemp, etc. The wood includes square wood, round wood, planks, wood blocks, etc., and the metal includes copper, steel bars, and angle iron. , iron wire, iron nails, etc. The comprehensive materials include brown rope, brown silk, plastic film, etc.
1. Preparation mud processing.
Remove impurities directly from the mud directly from the ground, pound it with a mallet and wooden sticks for manual smelting, and if possible, use a tamping machine for processing. If the mud is too wet, it should be placed in a ventilated place indoors first, and let the soil dry to achieve a suitable level. If the mud is too dry, it needs to be smashed, put it in a container, soak it with an appropriate amount of water, and then pound it. Finally, it is better to make the mud moderately soft and hard without sticking to hands. The processed mud The pieces should be placed in a cylinder or other containers, covered with a damp cloth or plastic cloth to maintain a certain humidity, and set aside.
2. Take the inner skeleton.
Wood, wood blocks, iron wire, steel bars, iron nails, etc. are commonly used to build the skeleton. The skeleton of clay sculpture is like the human skeleton, which plays the role of support and connection. It is the basic condition of clay sculpture and cannot be ignored. Most of the campus stone sculpture use abstraction and symbolism, metaphor and paradox to express, especially the campus stone sculpture in our country, which are generally commemorative, symbolic, motivating, decorative, etc., highlighting ideological aesthetics, emphasizing the sublimation of moral education, or emphasizing It expresses human wisdom and the eternal pursuit of truth, goodness and beauty.
Pay attention to the skeleton:.
The skeleton should be firm to ensure the stability of the clay sculpture, and it will not tilt or collapse after being filled with clay.
After the mud is piled up, it is necessary to prevent the mud from falling off and the frame not to be exposed.
To reflect the general shape of the stone carving.
The frame used should be simple and easy to change and disassemble when making molds.
3. Make a large pile of mud.
After the mud and the skeleton are ready, you can start to apply the mud. Spray water on the skeleton first, so that the mud and the skeleton can be firmly combined and not easy to fall off. On top, press firmly with your hands, pat it firmly, and then add mud layer by layer. Use a mallet or a mud board to smash the mud firmly and stick it firmly. In the shaping of local details.
Stone carving is a three-dimensional entity. Every time a piece of mud is added, the relationship between various perspectives must be taken into account. The stone carving table must be turned frequently to observe and compare continuously. The mud should not be piled up at one time, but only need to be piled up in a large shape.
4. In-depth shaping
On the basis of the large shape and accurate proportion, it can enter the stage of in-depth shaping.
With the deepening of the parts and details, the volume of the clay sculpture is gradually in place. The part should be compared with the whole frequently to make the part obey the whole.
In the process of in-depth shaping, it is necessary to constantly adjust and grasp the relationship between the whole and the part, and to deal with the relationship between the part and the details. Only the part can be done correctly, and the part can be done correctly, and the whole can be enriched and perfected.
Often the energy is very concentrated when deeply depicting the part, and often the time spent on one surface is too long and the stone carving table is forgotten to turn.
In addition, pay attention to the symmetrical relationship, you can draw the center line on the clay sculpture to check, compare and correct.
5. Adjust and unify
In the in-depth stage, it is inevitable that some local details will be overly prominent, the major turning points of the body will be weakened, the bodies will lack coherence, or the processing will be rigid, etc. In the stage of adjustment and unification, it must be adjusted to the overall relationship.
In the process of making clay sculpture round sculptures, pay attention to spraying water on the clay sculptures frequently, especially in summer when the water is easy to volatilize, so it is necessary to spray water regularly to keep the mud at an appropriate dryness and humidity to shape the shape. In winter, when the temperature is low, the clay sculptures are like If you don`t pay attention to keeping warm, the whole clay sculpture will crack after freezing, so you should work in a warm indoor studio, so that the clay sculpture will not crack. After each work, you should wrap the clay sculpture with plastic cloth to make the clay sculpture not easy to crack , its moisture is not volatile so that it can continue to be shaped.
