Water-based materials are "cooked mud" made by repeatedly mashing and kneading raw mud with water, which is characterized by strong dryness, softness and non-stick to hands, and moderate humidity. This kind of mud is easy to obtain and has great plasticity. Cooked clay can be used to shape prototypes from small clay sculptures to large sculptures. There are many colors of soil, and it is more suitable for beginners to choose lighter soil.
Sludge is a man-made substance. It is softer and more viscous than ordinary mud. Because sludge is made of waste rubber, wax, vegetable oil or engine oil, talcum powder, etc. , not suitable for dry cracking. It can be used repeatedly for a long time at room temperature. At low or overheated temperature, sludge will become too hard or too soft, with poor plasticity. If the novice sculptor uses sludge in winter, it is best to have heating facilities indoors to improve the humidity and keep the room temperature; If there is no heating condition, hot water can also be used to soften the sludge. When in use, pour a basin of warm and humid water and put the sludge into the basin for heating. When it is soft, take it out and use it. In addition, put the sludge by the fire. Rub your hands repeatedly until they are soft. The summer climate is hot, and sludge is easy to soften. When molding, direct sunlight should be avoided on the statue, and it must be molded in a cool and ventilated place.
Oil sludge has good dryness, strong toughness and is not easy to break, which is suitable for dry rubbing creative manuscripts and smaller sculptures. At present, the sludge sold in the store is colored, and it can be used after repeated stirring and rubbing until it is the same color. Do not mix impurities in the process of sludge reuse, so as not to affect the molding. When not in use, it should be sealed in a plastic bag and can be used for a long time.
The auxiliary materials of sculpture are: wood, metal and comprehensive materials. Auxiliary materials are materials to enhance the firmness of sculpture, which can be used as human body, objects and bones.
Wood materials include square timber, logs, boards and blocks.
Metal materials include steel bars, angle irons, steel pipes and lead wires. Can be used to fasten the inner skeleton of sculpture;
Comprehensive materials include bricks, straw ropes, foam plastics, etc. Can be used as a "filler" to increase the internal volume of the statue. Adding less mud to the surface can reduce the self-weight of the statue, but it is not necessary to use it in sculptures with small heads and busts, and it can be used appropriately in large sculptures.
