Problems solved by technology
[0004] In traditional craftsmanship, due to the different chemical composition of raw materials and the control of firing atmosphere, the raw materials and firing process of traditional ivory white porcelain have been lost. The production and promotion of ivory white porcelain are restricted; especially with the decrease of high-quality raw materials in recent years, the output of ivory white porcelain has been decreasing year by year. The control of ceramic raw materials and the improvement of firing technology are necessary means to inherit and promote traditional Dehua ivory white porcelain. In the process of improvement, it is necessary to ensure that the improved porcelain has the closest artistic effect to the traditional Dehua ivory white porcelain, and at the same time reduce the cost of ivory white porcelain and increase the firing rate. The selection of raw materials and the control of the firing process are technical problems that must be solved.

Abstract
The invention belongs to the field of ceramic products, and in particular relates to a Dehua ivory white porcelain and a preparation process thereof. The Dehua ivory white porcelain prepared by the present invention includes lard white body and lard white glaze, and the lard white body is made of Dehua kaolin, low-temperature clay, low-temperature stone, Dehua quartz, and pyrophyllite 18-25%. Made by comparison, the lard white glaze is made of low-temperature stone, pyrophyllite, Dehua Yangshan limestone, quartz, and Dehua kaolin. The Dehua ivory white porcelain provided by the present invention selects raw materials with large reserves and low prices as raw materials for lard white body and lard white glaze, and strictly controls the chemical components of the raw materials. Introducing trace amounts of rare earth elements cerium and praseodymium into the raw materials of the glaze can make the body and glaze appear milky yellow lard color, making the porcelain fine, dense, moist, lard color, soft in color, firm in white, and as white as fat , slightly yellow, has the closest artistic effect to traditional Dehua ivory white porcelain.
Description
technical field [0001] The invention belongs to the field of ceramic products, in particular, the invention relates to a Dehua ivory white porcelain and a preparation process. Background technique [0002] Dehua white porcelain originated in the Song and Yuan Dynasties, was famous in the Ming Dynasty, and was extended in the early Qing Dynasty. It has a unique style in the white porcelain system in my country, occupies an important position in the history of ceramic development, and has the reputation of "Oriental Art" internationally. .
