Abstract

The invention discloses a demold-formed Jun porcelain. The demold-formed Jun porcelain comprises a green body and a glaze, the green body is formed by demolding a ceramic slurry under a high pressure,and the ceramic slurry comprises talc, feldspar, kaolin and carboxymethyl cellulose; the glaze comprises a black ground glaze and a golden dot glaze, and the black ground glaze is prepared through the following steps: crushing weighed melilite, white feldspar, talc, plant ash, iron ore, magnesium ore, calcium phosphate, sodium silicate, kaolin and a black catching agent, crushing, placing and ball-milling the crushed materials in a ball mill, adding water to make the mass concentration of the glaze reach 45-52%, and carrying out wet milling for 5-8 h to make the fineness reach 200 meshes; andthe golden spot glaze is prepared through the following steps: adding water to weighed melilite, albite, kaolin, soda lime, talc, quartz, bone ash, iron ore and blue powder to make the mass concentration of the glaze reach 48-56%, and performing wet grinding for 10-13 h to make the fineness reach 200 meshes. The process research and development of the new product are of great significance to developing the Jun porcelain, and fills the blank of Jun porcelain glaze color varieties.

Description

technical field [0001] The invention belongs to the technical field of ceramic preparation technology, and in particular relates to a demolded Jun porcelain and a preparation method thereof. Background technique [0002] Jun porcelain originated in the Eastern Han Dynasty. It is one of the five famous kiln porcelains in the Song Dynasty. It is famous all over the world for its unique art of kiln transformation. It is known as "gold is priceless and Jun is priceless" and "a family is rich, but it is not as good as a piece of Jun porcelain". When making Jun porcelain, although the current technology has achieved a lot Great progress, the traditional firing process of Jun porcelain includes pre-firing, oxidizing atmosphere firing, reducing atmosphere firing and the final cooling process, but the firing process is due to uncertain factors such as raw material factors and firing temperature control. Jun porcelain products that are difficult to fire and handle. [0003] With the...
