1, the general production technology level is high, and the modern production traces are obvious. In order to improve production efficiency in the Republic of China, all kiln factories adopted mechanized or semi-mechanized processing procedures to varying degrees.
From the steps of material taking, mud refining, blank making, air drying and molding, the produced blank is basically an assembly line operation, so the blank is uniform, uniform in thickness, accurate in rotary cutting, clean and tidy, with fine tire soil and few iron stars.
2. Well-known tunnel kilns are generally used in kilns, and the fuels are mostly coal, gas and oil, so the kiln temperature rises, the temperature difference is small, and the objects in the kiln are evenly exposed to fire. Porcelain fired in this way is generally completely porcelain-like, not easy to deform, with smooth glaze and firm carcass. When played by hand, the sound is crisp and lingering.
3. Glazes are all processed mechanically, so the glaze is even and clear, delicate and soft, and not dazzling. Under the magnifying glass, you can see that the bubbles are arranged very evenly and the size is the same.
4. All kinds of pigments are usually prepared scientifically, and traditional mineral pigments are not used, so the purity of pigments is improved, impurities are less, and the color is fresh and shiny. Moreover, because small kilns are mostly used for secondary color burning, the temperature, time and fire direction can be well controlled, so there are few colored faces burned.
