Abstract

The invention discloses a manufacturing method for jun porcelain. The method comprises the following steps: step 1, putting a qualified blank body subjected to ash removal treatment into a baking ovenat a temperature of 35-40 DEG C for baking for 3-4 hours; step 2, carrying out glazing; step 3, carrying out glaze firing, wherein the glaze firing comprises pre-firing, firing in an oxidizing atmosphere, and firing in a reducing atmosphere. The temperature in the furnace is increased at a constant speed from 1000-1050 DEGC to 1400-1500 DEG C; then fresh air is stopped from being conveyed into akiln; and nitrogen is conveyed into the kiln, wherein in 0-3 hours, the conveying amount of the nitrogen is 0.002-0.003 m<3> / s, in 3-7 hours, the conveying amount of the nitrogen is 0.0005-0.001 m<3> / s, and in 7-9 hours, the conveying amount of the nitrogen is 0.003-0.004 m<3> / s. The invention also discloses jun porcelain manufactured by the manufacturing method for jun porcelain. The preparationmethod provided by the invention has the advantage of low rejection rate, high precious product rate, simple operation and the like.

Description

technical field [0001] The invention relates to the field of porcelain production. More specifically, the present invention relates to a Jun porcelain and its manufacturing method. Background technique [0002] Jun Porcelain is the first of my country's "Five Famous Porcelains". It is famous all over the world for its unique kiln transformation art. In the traditional production method of Jun porcelain, 70% of the products will be scrapped during the firing process, and the treasures among them are even rarer, and most of the glazing methods need to be completed manually, the quality is not easy to control, and the glazing is uneven. Contents of the invention [0003] It is an object of the present invention to solve at least the above-mentioned problems and to provide at least the advantages which will be described later. [0004] Another object of the present invention is to provide a Jun porcelain production method with low rejection rate, high treasure rate and simpl...
