The ancient Chinese have developed a pottery technology that is still impressive even by modern standards.The pottery process is known as the slow-baked turning kiln. It is a unique pottery technology because of its complicated production procedures and its ability to produce high-quality pottery products.
The name of the slow-baked turning kiln processes comes from the baking process. After the clay is kneaded, it is placed in a large container and baked at high temperatures. As the container gradually rotates, the clay is kept evenly heated throughout the process. The heat used is usually around 1000 degrees Celsius, and the rotation of the kiln is slow and evenly paced, roughly one turn per hour.
The slow-baked turning kiln has numerous benefits. The slow, even baking process prevents the pottery from overworking and warping, resulting in strong and durable products. The even spread of heat throughout the clay helps prevent uneven drying, a common fault in pottery production. The slow-bake rotation also allows other ingredients to be mixed with the clay before it is baked, leading to color changes in the finished product.
The slow-baked turning kiln can be used to produce a range of pottery products, from tea cups to vases. The raw material for the kiln is usually clay; however, other materials such as potash, lime and wood ash can also be used. The clay is first washed clean and kneaded before it is shaped into various pottery items.
After the pottery is shaped, it is left to dry for around two to four hours. Once dry, the pottery can be placed in the slow-baked turning kiln and baked gradually. As the pottery is turned in the kiln, the heat is evenly spread and the moisture is slowly released.
Once the slow-baked turning kiln process is complete, the pottery is taken out and cooled. After cooling, the pottery is polished and painted according to the desired style and design.
The slow-baked turning kiln process has been used in China for centuries and is still used today. It is a remarkable piece of ancient technology due to its intricate production methods and its ability to create beautiful, consistent and durable pottery items. The slow-baked turning kiln is a testament to the artistry and skill of the Chinese people throughout the ages.
