With its unique clay materials, exquisite carving techniques, and unpredictable kiln-changing techniques, Yuxingtao is full of unique qualities of the rich colors of the layers of the ancient pottery.

According to the "Zhixian County Records" in the 35th year of the Republic of China, "I have cultivated pottery, forgive the invention before the Tang Dynasty, and to the Tang Dynasty and benefit from exquisiteness. In the nine years of the Republic of China, the village of the seventy-year-old Pingxin Village in the east of the city found the Xiaoyao Dagu, built in the mountains. On the side of Ning Dao’s Taoist monument, it is a four-foot-high giant system with a Tibetan pottery pot. This tablet is engraved with the words of Tang Kaiyuan twenty years (AD 732). It has been 1,188 years since then. I have a long history of clay pottery." In the summer of the 28th year of the Republic of China, the Lijiang River Shilin Lin Shengwu carried out a research on the Ning Dao Gong Tao monument: "This ambition...the quality is clay. When it was first unearthed, it was extremely crunchy, broken into ten pieces, and the villagers were freely divided. People discerned their dynasties and characters. In the seventeenth year, Wu Yin was the chief of the county, searching for the golden stone, and collecting the pieces together, reading the first and the last, beginning to know the Tang Dynasty, and knowing that Ning Yue County (now Qinzhou City) fifth The epitaph of the Shilin Shining Daobao... I have been recorded for thousands of years, and there have never been more than a thousand words of Tao Yuan. This is a thousand or six hundred words... It is the first pottery in China." After more than a thousand years of ups and downs and ups and downs since the Sui and Tang Dynasties in the Northern and Southern Dynasties, I have experienced the constant exploration, inheritance and development of the artists. With the unique local pottery resources, the rich cultural connotations have been integrated into the creation of ceramic art, forming a set of ceramics in the world. There is no special firing technique in the same category. With its unique skills and quality, Qinzhou Yuxing Tao, as early as 1915, participated in the “Panama Pacific World Expo” in San Francisco, USA, and won the gold medal. This is the first time in the history of Chinese ceramics. The “World Expo Award” won the world famous reputation.

Yuxing pottery quality technical requirements (1) product categories. Arts and crafts pottery and daily pottery. (2) Composition of raw materials. 1. White mud, the ore type is weathered residual clay, which is microscopic scale muddy structure and soil-like structure. 2. Purple red mud, the ore type is weathered purple red mudstone, which is microscopic scale muddy structure and massive structure. 3. Chemical composition: raw material name chemical composition range SiO2Al2O3K2ONa2OCaOMgOFe2O3TiO2 purple red mud 58 ~ 6615 ~ 19 ≥ 1.5 ≤ 0.8 ≤ 1 ≤ 1.5 ≤ 8 ≤ 1 white mud 62 ~ 6716 ~ 17 ≥ 1.5 ≤ 0.5 ≤ 0.5 ≤ 1.0 ≤ 5 ≤ 1 ( c) Processing technology. 1. Mud-making process: white mud is stored in the sheltered place and air-dried, and the purple-red mud is stored in the open air, weathering and turbidity. Then mix the ball mill, sieving, stale, stirring, pumping and pressure filtration, the darkroom is stale for 15 days, and then vacuum-pressed to make mud strips and stale. The fineness of the mud is less than 1% in the range of 250 mesh sieve. The plasticity index is greater than 2.5. 2. Molding process: (1) Arts and crafts pottery: manual molding, mechanical auxiliary molding and grouting molding. (2) Daily use ceramics: According to different product types, manual forming, mechanical forming and grouting are used respectively. 3. Carving and decorating process: According to the design requirements, give full play to the function of carving knife, especially emphasizing the use of knives and pens, pay attention to mastering the strength, and wave it. The main point is "outside the line, in the shape of a line." 4. Firing process: Different firing methods are carried out according to different forming methods and utensils. The firing temperature is 1100 ° C to 1180 ° C. During the firing process, the heating curve, the firing temperature and the control of the firing atmosphere are mainly mastered. Throughout the firing schedule, we will focus on the combination of slow burning, flat burning and fast burning. 5. Grinding and polishing process: Firstly, the surface of the surface of the fired product is rough-grinded, then finely ground and deep-processed, and then finely ground. After the polished product is baked, a thin layer of food paraffin is used, and the cloth wheel is used. The excess wax layer on the surface of the product is discarded to make the texture and color of the surface of the product more smooth and soft. (4) Quality characteristics. 1. Appearance quality characteristics: (1) Daily-use ceramic products: the texture is delicate and firm, the sound is knocking, and the color is soft. (2) Arts and Crafts Pottery: The texture is delicate and strong, the sound is knocking, the color is smooth and soft, the decoration is finely carved, and the texture is antique. 2. Physical and chemical indicators: (1) Thermal stability: heat exchange at 200 ° C to 20 ° C three times without cracking. (2) Water absorption rate: 1.5% to 5%. (3) Lead and cadmium dissolution: lead ≤ 0.5mg / L, cadmium ≤ 0.05mg / L. 3. Safety requirements: Product safety indicators must meet the relevant regulations of the state for similar products.
