Ceramics is a folk handicraft, and there are ancient porcelain workshops, ancient town kilns, and pottery painting workshops in some exhibition areas and ancient kiln scenic spots. Modern people use these ceramics to decorate their homes and create another antique and beautiful scenery. How is ceramic processing made? What are the steps involved? Now let's learn how such beautiful ceramics are processed!


How to do ceramic processing? There are several steps to do ceramic processing:

1. Refining mud: First, go to the mining area to collect porcelain stones, take them back and break them into egg sized pieces. Then, use a water hammer to pound them into powder, wash them to remove impurities, and let them settle into brick shaped mud blocks. After the mud is formed, mix it with water to remove the residue. Rub or step on it with your hands to remove the air from the mud, and then evenly distribute the mud in the water.


2. Pulling: Pulling requires the use of a pulley car, throwing mud balls onto the pulley car and then starting to turn the wheel. Afterwards, use random techniques to bend, stretch, retract, and draw to create the shape of the billet. Drawing blanks requires a lot of technology. Firstly, one needs to be familiar with the shrinkage rate of clay, which is generally around 18-20%. The size can be freely adjusted according to different types and sizes.


3. Printing blank: In this process, the shape of its printing mold is to install the internal curve of the blank to rotate and shape, then air it to half dry, and then cover the blank on the mold seed, evenly pat the outer wall of the blank, and then demold.


4. Li Qi: First, place the Qi on the windlass, and when starting to rotate the wheel, use a knife to rotate it. When the body thickness is appropriate and the surface and interior are smooth, it is sufficient.


5. Drying the blank: This step is simple, as long as the processed blank is placed on a wooden frame for drying.


6. Carving: Carving tools are tools made of bamboo, bone, or iron to carve patterns on dried bodies.


7. Glazing: Ordinary round porcelain is glazed by dipping or swinging, while chiseled and large round porcelain are glazed by blowing. After glazing, they are placed in the kiln for firing.


8. Kiln firing: First, put the porcelain into a bowl and then bake it in a container to avoid porcelain contamination. It needs to be roasted for about one night at a temperature of around 1300 degrees Celsius, using pine wood as fuel. Of course, technical guidance is also needed during roasting, measuring the temperature, understanding changes in kiln temperature, and determining the ceasefire time.


9. Colored painting: Glaze colors such as five colors, pink, etc. are used to depict patterns and fill colors on the glazed surface of fired porcelain, and then baked in a red furnace at low temperature, with a temperature of about 700-800 degrees.
