Embodiment 1

[0035] The method for preparing the body and glaze of Longquan celadon that is fully utilized without elutriating the raw ore in the first embodiment of the present example is prepared by the following method:

[0036] (1) Preparation of slurry

[0037] Each raw material used by the billet is weighed accurately according to the following mass percentages:

[0038] Baoxi china clay 15.5%, Zhuxiang china clay 13.5%, Siyuan china clay 14.5%, kaolin 55%, organic additive CMC 1.5%;

[0039] After mixing evenly, carry out ball milling for 8 hours, remove iron and pass through 250 mesh, and obtain slurry after staleing for 12 hours; mud cake with good plasticity is obtained after slurry is squeezed; mud cake is vacuum smelted, formed into a green body, and then dried and biscuit fired , get the green body;

[0040] (2) Preparation of glaze slurry

[0041] The raw materials of the glaze are weighed accurately according to the following mass percentages:

[0042] Calcined Huangshi ...

Embodiment 2

[0051] In this embodiment, a method for preparing a Longquan celadon body and glaze that can be fully utilized without elutriating raw ore is prepared by the following method:

Abstract

The invention discloses a preparation method of blank-purposed raw ore full utilization Longquan celadon blank body and glaze. According to the concrete method, a blank is prepared from the following recipe raw materials in percentage by mass: 10 to 20 percent of Baoxi porcelain clay, 10 to 25 percent of Zhuxiang porcelain clay, 10 to 25 percent of Siyuan porcelain clay, 35 to 65 percent of additional mineral and 0.01 to 3 percent of organic additives. The preparation method of the blank-purposed raw ore levigation-free full utilization Longquan celadon blank body and glaze has the advantages that the direct full utilization of the Longquan celadon blank-purposed raw ore without levigation can be realized; in addition, the manufacturing cost of Longquan celadon is reduced; meanwhile, the cheap additional mineral and organic matters are introduced for achieving an obvious effect on the blank body forming; the manufacturing cost of the Longquan celadon is reduced; the method is suitable for industrial mass production.

Description

technical field [0001] The invention relates to a preparation method of a daily-use ceramic body and glaze, in particular to a preparation method of a Longquan celadon body and glaze in which raw ore is fully utilized for the body. Background technique [0002] my country's Longquan mine is rich in resource reserves, but due to the high quartz content of china clay ore, a large amount of raw material tailings will be produced after elutriation. At present, the processing methods of celadon ore tailings are mainly accumulation or landfill, which not only occupies a large area and wastes a lot of land resources, but also causes serious pollution to water and soil resources, destroys the ecological balance, and hinders the sustainable development of the economy. Continuous development. Therefore, the full utilization of Longquan celadon ore tailings resources is an important way to realize the sustainable development of Longquan celadon ore resources. This is not only a strate...
