Preliminary sketches in plasticine

As we have already said, the ability to draw and sketching from life, as well as sculpting study sketches and sketches in clay or clay or plasticine. Classes in modeling will help the carver find scale, composition, clarify details, develop three-dimensional vision, a sense of space, the material, will make it possible to determine the correctness of the composition when viewed from all sides, the ratio of masses and details. В Modeling is easy to add missing or remove excess. Clay and plasticine are soft materials, convenient for sketches and outlines. The place for modeling, as well as for carving, requires light, with an overhead source of lighting. If sketching is done during the day and evening, make sure that the light does not Do not let the light change in strength or direction. The model should be at the artist’s eye level. When working in a small room with small figures, busts, sculpting machine Place it on a table. It is made of wood in the form of a board mounted on a stool with Short legs. The upper board should rotate on a metal or wooden rod. For better rotation, put on the axle a cross with rollers made of short Tubes. Attach a ring of sheet iron under the rollers to the lower board. The dimensions of The upper board depends on the scale of the molding sketch. It can be about 30 × 30 cm, 50 × 50 cm with a thickness of 3-4 cm. A rotating board saves the sculptor from The turning board saves the sculptor from having to move around the work while sculpting and when looking at it. To It is enough to turn it by putting the other side under the previous light. The best tool for sculpting is the human hand and fingers, which have a good sense of volume and form. With practice, this feeling develops. The hand sort of sees volume. But for to work out small details, to thoroughly refine the relief and texture of the surface you’ll need stacks. These are smooth wooden or metal plates of various forms, 16-20 cm long and 1-3 cm wide. It is not particularly difficult to make them yourself. You will need strong species: beech, hornbeam, best of all boxwood, birch and maple are also suitable.
Metal rings are used to remove excess clay. To the wooden handle screw a round or triangular loop of steel wire to a wooden handle. To compact the clay layer and mold large parts, make a wooden hammer cylindrical or square shape, in size and weight it corresponds to the mallet. The best material for modeling is green clay, also suitable bluish-gray. You can use clay and other colors, but make sure that it was not too of sand (it prevents sticking), and, diluted with water to the right consistency, The clay may be of other colors, but make sure that it does not contain too much sand, which prevents it from sticking together. To prepare necessary amount of clay, it is first dried in the air, then broken into small pieces and sifted to get rid of stones. Poured into an enameled or galvanized crock (tank, bucket) and pour water so that over the surface raised islands of clay. After a day the water is absorbed, and the clay is ready for use. Before sculpting, taking the lump, knead it in your hands. When creating a sketch in clay, mold first The overall shape, the large details, and then move on to the details. After finishing the sculpting session, Cover the work with a damp cloth and dry or replace them with polyethylene film, Pre-moisten the product slightly with water. If clay is not available, use plasticine. At home it is more convenient, Clay is cleaner, almost does not dry out, does not crack and does not require soaking, but it But it should not be kept in a cold or very warm place, or near heaters, or in the sun. in a cold room or in a very warm room near heaters, in the sun. In the first case, a lot of harden, in the second will soften. The optimum temperature is Optimum temperature is 18-22°C, which is usually suitable for home use. Modelling clay or eglin Suitable for modeling small easel paintings that last a long time. The surface will Over time, if you do not cover the product with a cloth, cellophane, compacted, covered with crust and dust. Eglin sells large briquettes. It is harder than plasticine. If plasticine or If you can’t buy clay or eclin that is made for sculptors, buy a set of colored Kids’ Art Clay. It is a little softer, but more often on sale. You can Model using a range of colors. If you don’t feel like modeling with colored plasticine, it’s easy to turn it into a general brown mass. To do this, put the bars of the set in a saucepan with hot water, warming slightly with gas. For greater hardness, add paraffin there by slicing with a knife at the rate of one third to the mass of plasticine. After some time the plasticine will melt. Stir it with a stick and pour out the water, replacing it with cold water, so that the mass hardens faster. Take out the cooled mass – it is ready to work. It is easy to make a frame for a human, animal or bust figure. The main requirements: it must be strong, withstand the weight load and not stick out where not necessary from the molding. On a wooden platform of board or thick plywood with staples and bolts or nails fasten verbosil – a metal base. On it are mounted frame parts, resembling the main forms of the sculpture. If necessary, wind the baked wire with attached wooden crosses at the ends, which better hold the parts. To model a bust, they use For modelling a bust, they use a block of wood or a bar.
A metal needle-rod is threaded vertically through a hole in the free flattened end of the verb and then poked into the center of a wooden table. On this base you sculpt your sketch – a statue, a portrait. Try to position the work so that the front side of it was directed in the opposite direction from the verb. When you have finished sculpting the sculpture, the needle is carefully removed. Then the entire sculpture is easily removed as well. A machine for attaching wooden workpieces to the table. You can also use a large vise for this purpose by inserting wooden or rubber plates between the metal planes of the vise and the workpiece. Make sure that the chisel does not jam into the metal during carving.
