Dai pottery handicraft clay formula and manufacturing process thereof
Technical Field
The invention belongs to the technical field of ceramic artwork manufacturing, and particularly relates to a Dai ceramic artwork clay formula and a manufacturing process thereof.
Background
The development history of the ceramic is an important component of the Chinese civilization history, China, as one of four civilization ancient countries, makes outstanding contributions to the progress and development of human society, wherein the invention and the development of the ceramic have unique meanings, and the China has different artistic styles and different technical characteristics in different generations in history. In China, the generation of ceramic manufacturing skills dates back to the era from 4500 to 2500 years ago, the scientific and technical achievements of Chinese workers and the pursuit and shaping of the beauty are reflected in many aspects by ceramic manufacturing, and very typical technical and artistic characteristics of each era are formed.
The Dai pottery is generally called Dai pottery for short, and Yunnan pottery has about 4000 years of history, but has been used as a Dai which is very hard in minority people for more than 3000 years of mastering pottery manufacturing technology. The people of the Dai nationality who have the southern religion of the seat of belief of the whole civilians create extremely rich religious artistic forms, which are fully reflected on the pottery made by the Dai nationality. Dai nationality pottery is also widely applied to the roof and ridge of the temple, reflecting people's worship about nature and nature spirit. Such as a small tower in the center of the positive ridge of the temple, a peacock, a dragon, a phoenix, a lion, a elephant, etc. on the ridge, flame-shaped tiles continuously arranged on the ridge, a 'shape of a animal' placed on the dragon head and the phoenix body of the temple, etc. The tile hanging shape of the roof is generally obtained by processing rhizomes, flowers and plants, trees and the like of plants commonly seen in Dai nationality regions, commonly seen in shapes of vegetable buds, rambutan flowers, Japanese banana flowers and the like, and glazing to prevent blackening after being exposed to the sun and rain. The Buddhist worship is decorated by pottery Buddhist animals such as peacocks, dragon, phoenix, lion, elephant, etc. because peacocks are inhabited on both sides of the stream in the Dai nationality, the feeling of warmness and softness and the feeling of luckiness and happiness are brought to people. The dragon and the phoenix are influenced by the Chinese culture, which represents good luck and happiness.
The traditional Dai pottery manufacturing process needs pure manual firewood pottery burning, and 10 processes of digging, pugging, fermenting, kneading, pulling blank, making pottery, trimming blank, carving, drying, kiln loading, firing and the like can be carried out 5 days and 5 nights, fire can not be cut off after the process needs to be watched at night in turn in the 5 days, all processes do not need machines, and the process is accumulated completely by the experience of a kiln worker. The temperature in the kiln reaches more than 1000 to 1400 degrees. The glaze before firing is one color, and after the ceramic is taken out of the kiln, the ceramic is changed into different color systems, the ceramic with the kiln change is unique, the glaze on the ceramic is natural ash falling glaze, is glittering and translucent, is not colored or glazed, and has no harm to human bodies.
The Dai nationality has a set of complete production and living modes, and has the interweaving of original religions and Buddhism beliefs, which are the origin of Dai ceramics, the spirit of the Dai nationality and the essence of the Dai ceramics. The culture, art and inheritance of the Dai generation are closely related to the Dai pottery. Along with the development of society, Dai nationality people increasingly look at the protection of traditional culture, Dai pottery artware is an excellent carrier for culture transmission and inheritance due to exquisite process and historical precipitation of Dai pottery artware, but the steps of batch high-efficiency production of Dai pottery are hindered due to the long-term traditional handmade process of Dai pottery and the extremely regionally characteristic making raw materials, so that the Dai pottery is in marginal pottery art culture for a long time and is difficult to enter the public society; therefore, the new and improved manufacturing process is sought, the production efficiency of the Dai pottery products is improved, and the Dai pottery products are a necessary way for the future propagation and development of Dai pottery culture.
