1. Clay strip coil molding method.
Take an excess of mud and use both hands to naturally pinch and transform it into a round rod shape.
Place the round clay stick horizontally on the task table and rub it evenly with your fingers, rubbing while rolling, moving your left and right fingers, from thick to thin.
Naturally and gently knead the mud strips, and knead them into mud strips of consistent thickness and average size according to the needs.
Put the mud strips on the turntable to make a bottom, and then press the mud strips while turning, while turning the turntable, increasing the height in turn, and finally making the shape of the person's needs.
Each layer added requires the surface to be flattened, compacted, and evenly pressed to avoid cracking when dry.
You can use clay paddle, hand clap and hand pull to adjust the shape, and you can save the original handwriting results of the clay strip coil.
2. Hand kneading (sculpture) molding method.
Hand kneading, sculpture molding method is one of the most primitive, most fundamental, and most sketchy methods of making pottery, and it is also the most fundamental exercise for beginners to experience the thickness, softness, hardness, dry and wet level of clay, you don't have to do things, just kneading by hand, there is a greater degree of freedom, you only need to use your hands to knead the clay into the shape you want to shape, which is also one of the most old pottery methods. You can also use a sculpture knife or other things to make a statue, and hollow out the statue when the mud is half dry.
3. Clay plate forming method.
Clay tablet forming is to roll the mud blocks into mud tablets manually or by a mud press, and then use these mud tablets to shape. When rolling the mud board, the mud should be placed in the center of the two pieces of cloth, and the cloth blocks should be dispersed from the middle of the mud blocks to the surrounding areas), pay attention to the thickness of the mud, and meet the needs of the pottery works made. The tenderness of the clay can be applied to the production, and it can be molded like a cloth when it is made, and the sturdiness of the clay board can be molded like a wooden board.
The use of clay tablets is very limited, from flat to three-dimensional, can be used to transform the shape, can be applied to bend and roll when the clay board is wet and soft, to make a natural, beautiful shape, can also be used when the clay board is semi-dry to make straight utensils.
4. Impression (blank) forming method.
Impression (blank) molding is a method of using gypsum molds to mold. Since ancient times. This method is generally used in the production of ceramics, generally we use gypsum mold, the master mold can be made of gypsum or clay, and then turned into a number of molds according to the modeling, after the mold is dry, the body can be printed, and the mold is formed.
When printing the impression, the force should be averaged, pressed, and the shape should be printed out in good condition, and the complex works should be printed by the mold, and then composed, and the interface should be bonded with mud, and the damaged body should be repaired after the body is demolded, and the excess should be scraped and lost. This method can reproduce the product in large quantities, which brings a lot of convenience in the production of ceramics, and can make different textures and other decorative results on the mold according to the needs of the ego.

Hello. The basic molding methods of pottery production are: blank molding, mud board molding, mud strip plate molding, and gypsum mold molding.
Blank forming is to stretch the mud in the watery semi-cured state during the rotation process; It is easy to form a large and complete surface in the molding of the mud tablet, and the forming speed is relatively fast; The mud strip coil forming is to roll the mud into a uniform round strip, and then make a spiral upward spiral to build the shape; Gypsum mold molding is to use gypsum as a mold to harden and dry the mud (mud).

1. Prepare the raw materials for processing, and knead the clay until it becomes smooth and has the same density.
2. Then put the soil in the center of the blank drawing machine, start to draw the blank molding, pay attention to the water content in the clay during the blank drawing process, make the soil more compact, and put the drawn blank under the light to dry.
3. After drying, you can engrave your favorite pattern or word and glaze it on the porcelain.
4. Put it on the machine and burn it to 1240 degrees, then take it out.

Production method and process:
1. Pinch molding.
Kneading a small piece of clay into an animal or figure is the first step for many children to learn how to make pottery. Skilled folk artists can make many complex shapes by kneading and molding. There are also contemporary ceramists who use the method of kneading to create large-scale works.
Alternatively, many small parts can be made into a large sculpture by kneading and molding. Kneading is a very expressive technique.
The fingerprints left during pinching can also create a very interesting texture effect.
2. Clay strip molding.
It has been found in the pottery of primitive societies all over the world, and can still be seen in many folk pottery workshops today. The maker kneades the dough into strips of uniform thickness. The mud strips are then overlapped vertically according to the desired shaping rings.
The horizontal stripes on the surface of the utensils can be polished with hands or tools, or some of the stripes can be left for decoration.
The clay strip forming method can be used to make small pieces or large pieces. The size of the piece depends on the thickness of the clay strips. If the work is smaller, the clay strips will be finer, and if the work is larger, the clay strips will be rubbed larger.
Nowadays, there are manual or electric clay strip machines** everywhere, which replace the manual production of clay strips with mechanical methods, and the objects of making are far beyond the scope of traditional round utensils.
3. Clay chip molding.
Generally speaking, the maker can use different methods such as rolling with a rolling pin, cutting with steel wire, or patting to obtain clay chips.
Clay shards are the most common hand-shaped technique for sculptures or vessels. From simple square clay boxes to complex human figures, clay chips can be used. Clay chip molding is also one of the traditional crafts of Yixing purple clay pot.
Nowadays, there are clay flakes in various places**, which replace the role of the rolling pin with mechanical methods, and this clay flake machine is a good helper for making large-scale works.
Introduction to Pottery Craft:
The drying of the ceramic industry has gone through natural drying, chamber drying, and now continuous dryers, far-infrared dryers, solar dryers and microwave drying technologies for various heat sources. Although drying is a relatively simple technology, it is widely used in industrial processes, which is not only related to the quality and yield of ceramic products, but also affects the overall energy consumption of ceramic enterprises.
The energy consumption in the drying process accounts for 15% of the total fuel consumption of the industry, and in the ceramic industry, the energy consumption used for drying accounts for the proportion of the total fuel consumption far more than that, so the energy saving of the drying process is a major event related to the energy saving of the enterprise.

1. Blank forming.
Using the centrifugal movement generated by the blank drawing machine, during the rotation process, the mud in the aqueous semi-cured state is stretched and formed according to the design concept. The main feature of clay tablet pottery is that it is easy to form a large and complete surface, and the molding speed is relatively fast. The technical requirements for clay tablet forming are very high.
In order to do a good job in clay tablet molding works, it is necessary to master the technical issues such as clay tablet production, perception of the mud materials used, and mud tablet combination.
2. Clay strip coiling.
The mud strip method is a disc construction technique that is constructed and formed by mud strips. The mud strips can be kneaded by hand or extruded by the mud strip tool. Blank painting - Painting with pigments on vases, bowls, plates, jars and other utensils (blanks).
Plain firing: After the mud is dried, the kiln is loaded, and the first plain firing is carried out, burned to about 800 degrees, so that the mud is hardened, and then waits for cooling and out of the kiln.
3. Glazing. The plain fired porcelain can be glazed, and the inner glaze is applied first.
4. Burning. The glazed bottles need to be filled into the kiln again and subjected to positive firing, which needs to be fired at a high temperature between 1280 and 1310 degrees.
5. Decals. If the bottle needs to be screen-printed with other text descriptions or patterns such as logos and alcohol content, the surface of the fired bottle is pasted with glaze colored flower paper, and then put it in the oven for roasting, about 700-800 degrees.

Summary. Hello, glad to answer for you. Hello dear, the production step 1 of pottery, practice soil.
Take out 2-3 kg of the clay you just bought, rub it continuously until it becomes a chrysanthemum-like shape, and then drop the clay onto the table until it is smooth. This is to prevent the pottery ten hardness that I bought back.
First, there are voids, bubbles, etc., and the clay that has not been "practiced" will be prone to cracking in the process of drying or firing. 2. Prepare a bucket of water and pull the broken machine. Dip the trained soil in water and place it in the center of the machine.
3. Put the trained clay into the bucket and soak it so that it is easy to start making. 4. Press the ten pieces with the palms of both hands to make the ten pieces stick to the pulling machine. 5. Dip your hands with water, hold ten pieces in your hands, turn on the switch of the broken machine, and gently pull it up after the machine rotates.
Probably every time you make a turn, you go up a little bit in height. Then repeat the action of pressing, then pull up, press again, and repeat several times.
