Although Marble Sculpting is different from round sculpture in terms of expression and processing methods, the principle of learning and making from the whole to the part, from simple to complex, and step by step is still the same. A stone carving board is needed to make stone sculpture. A number of nails at different distances are nailed on the board, and lead wires are connected between the nails so that the mud can stick firmly to the board without falling off.
Depending on the size of the area, the head and bust stone sculpture are generally piled with mud four to six centimeters thick, and the surface should be flat. When making head stone sculpture, first choose an angle that is easy to express, such as the side, and use light from the upper side to make the model's body structure clear and undulating. The height of the model and the stone carving should be level with our line of sight, that is to say, the stone carving should be at right angles to the line of sight.
The production steps are to first draw the general outline of the object`s dynamics, proportions, and structure on the clay board, and then continue to pile up mud according to the outline or dig out the mud outside the outline first, and then carry out in-depth shaping as the basic level, that is, add higher ones , dig in low. Layers are very important for stone carving, so it is necessary to determine the large layers at the beginning, determine the high and low points, and then according to the shape and structure of the stone, use the compressed high and low ups and downs to shape until the adjustment is completed.
The problem that beginners of stone carving are likely to encounter is improper compression, which is like the problem of cutting half the thickness of a round carving and sticking it to the bottom plate. Therefore, stone carving must also master its laws, so that the progress will be faster. The outline must be drawn accurately, and the plasticine is changed during the plasticine process. If there is a change, it will be revised and corrected repeatedly. Separate the main layers and the direction of the surface, and the direction of the surface is based on the shape structure.
Under normal circumstances, it is necessary to compress the differences and differences between the front and back levels, the direction of entry and exit, and the angle. After compression, it is still necessary to maintain the correctness of the relationship between the front and back, the direction of entry and exit, and the angle. The part of the stone carving object close to the line of sight is less compressed, and the part of the object farther away from the line of sight is compressed more, and so on. The height and lowness of stone sculpture come from comparison, such as layers, volumes, and surface directions, which should be compared with each other.
The perspective relationship and the turning relationship of the surface should be clear. In this way, even if the mud is not raised, it will appear to be raised, and if it is not dug down, it will feel deep. Light is very important in stone sculpture, and we must know how to use the illusion relationship between surface and light. In addition, attention should be paid to the edge of the stone carving, which should maintain a certain thickness, which is determined according to the shape and structure, and should be rounded, so that people will not feel that it is cut in half and pasted on the clay board.
Efforts should be made to express the sense of volume and space on the plane, and of course the relationship between the whole and the part, especially the physical structure and volume, which will destroy the whole by improperly emphasizing the part. At the same time, attention should be paid to the depiction of the mental state of the characters.
