How to make ceramics
If you want to make ceramic ornaments, you must first take porcelain stones. Generally speaking, we collect porcelain stones from mining areas. First, we break the ore into the shape of an egg with an artificial hammer, and then break it into powder with a water hammer. After elutriation and removal of internal impurities, the precipitated porcelain stone is made into brick mud. Next, mix the mud with water, remove the slag, and knead it repeatedly with your hands or feet until the air in the mud is squeezed out and the water is even. Then we need to make ceramic ornaments with plaster mold according to the shape, and make them into the shape we need according to the mold. Generally speaking, most ornaments change the shape of the soil by force, so that the soil becomes the same shape as the mold. However, if we want to make hollow necklace ornaments, this molding method is not applicable, and we need to introduce mud into the mold for accumulation in order to finally get the shape we need.
Next, we will carve the specific shape of each ornament with a knife on the original basis. Whether it is a knife carving or a fire, the ornaments made will be rough and look rather unsightly. Even if it is worn on the human body, it may cause harm to the human body. So we will further polish the carved ornaments with gauze to make them smoother. Then air-dry the bad body of ceramic ornaments. Generally, the bad blank of ceramics goes through four stages: charcoal drying, anthracite heating drying, smokeless boiler steam drying and kiln drying. When making small ceramic ornaments, we only need to put the bad body on the wooden frame and air-dry it naturally. When the bad body is dry, we must paint it on its surface, usually with bamboo, bone or iron knife. Because it is hand-made, this means that each ceramic ornament will have subtle differences, but it just happens to be the unique charm of each ceramic ornament.
Finally, glaze the ceramics. Because the glaze water is unstable and particularly mobile, it may flow down during high-temperature firing. If there are traces of glaze water, then this ornament will be invalid. Therefore, after glazing, the periphery of the jewelry should be scraped clean to ensure that the glaze will not flow down. Next, the ceramic ornaments should be fired. In general, ceramic products should be put into baking containers to avoid pollution caused by contact between ceramic ornaments and kiln fire. The kiln burns for about a day and night, and then it can cease fire. Finally, we will paint the ceramic ornaments and bake them in a red oven at low temperature, so as to ensure that the color of the ceramic ornaments will never fade.
Method of identifying ceramics
First: look at the appearance. From the appearance, a good ceramic surface is fine, smooth and uniform, with few trachoma and magazine particles, not only glazed, but also fine and uniform on the unglazed side.
Second: try to feel. After looking at the appearance, we want to know whether the ceramics are fine and smooth, so we still need to touch them by hand.
Third: try the weight. Good ceramics will be heavier in your hand.
Fourth: test density. Everything has density. The lower the density of some things, the better. Ceramics have higher density. Then pay attention to the resolution density? In addition to the detailed appearance above, a dripping test is also needed. If the water absorption is slow or even invisible, then the density of ceramics is very high and it is a high-quality ceramic.
Fifth: listen to the sound. Good ceramics, when struck by hands or hard objects, sound crisp and pleasant.
The above introduces how to make ceramics and how to distinguish ceramics. Do you think you have a better understanding of China's traditional culture? In fact, not only that, but also you can make your own ceramics in the future. I think ceramics are really beautiful. I believe that everyone loves ceramics not only because they are beautiful, but also because they are specially made. Therefore, when you buy ceramic products, you must master the method of distinguishing ceramics.
