Abstract

The invention discloses a preparation method of celadon. The celadon adopts a mineral substance raw material and a high polymer material to prepare a blank material and a glaze material, wherein the blank material comprises a component A, a component B and a component C. The preparation method comprises the following steps of S1, preparing the component A, the component B and the component C; S2,preparing a slurry of the blank material; S3, forming a blank body; S4, biscuiting the blank body, wherein the biscuiting comprises a first stage, a second stage and a third stage; the temperature interval of the second stage is 200 DEG C to 600 DEG C, the temperature rising speed is 1 to 2 DEG C/min during the period, the air pressure in a kiln is kept between 0.2 to 0.3MPa, and heat is kept for20 to 30 min when the temperature is risen to 600 DEG C; S5, preparing a glaze slip of the glaze material; S6, glazing; S7, glaze firing. The preparation method provided by the invention is not only low in production cost and suitable for batch production, but also beneficial to improving the yield through reasonably controlling the temperature rise speed, the air pressure in the kiln and the processing time of different stages such as biscuiting and glaze firing, so that the produced celadon is high in strength, not easy to break, fine and smooth in porcelain, and high in gloss.

Description

technical field [0001] The invention belongs to the technical field of porcelain, and in particular relates to a preparation method of celadon. Background technique [0002] Longquan celadon is a treasure of traditional porcelain with Chinese characteristics. During the Southern and Northern Dynasties, people in Longquan, Zhejiang Province made use of the local superior natural conditions to manufacture celadon. Longquan celadon is known as the center of the porcelain garden for its glaze color as green as jade, bright as a mirror, and sound like a chime. A bright pearl, loved by celadon lovers all over the world. [0003] However, the current preparation method of Longquan celadon not only has high cost but also low yield, and is not suitable for mass production. Contents of the invention [0004] In order to overcome the shortcomings of the prior art, the present invention provides a preparation method of celadon, which has the advantages of low production cost, high yi...
