Formula and production process for producing high-quality porcelain by using poor-quality raw materials

The invention belongs to the field of ceramic production, and particularly relates to a formula and a production process for producing a high-quality porcelain by using poor quality raw materials such as weathered feldspar, porcelain sand, red soil and other poor-quality raw materials. According to the formula, the weathered feldspar, the black clay, the kaolin, the black talc and the porcelain clay produced in the Dehua are subjected to the production process with characteristics of reasonable formula and right control so as to produce the daily-use porcelain meeting the export standard, such that the bottleneck problem constraining the Dehua exported ceramic enterprise development is solved, the production cost is substantially reduced, the raw material supply time is shortened, the economic efficiency is improved, the market competitiveness of the exported ceramic enterprise is enhanced, and the great promotional value and the great social and economic benefits are provided.
