Hand-drawing production method of in-glaze decoration of calcareous porcelain

Abstract

The invention provides a hand-drawing production method of in-glaze decoration of calcareous porcelain, belonging to a ceramics production method. The method sequentially comprises the steps of: a, shaping a porcelain body: the shaped porcelain clay body is fired for 25 to 35 minutes to shrink and fix the shape of the porcelain clay body to obtain the porcelain body; b, firing Xuande porcelain: a layer of flux is sprayed on the surface of the porcelain body and the porcelain body is fired for 18 to 22 minutes at the temperature ranging from 700 to 900 DEG C to obtain the Xuande porcelain; c, colored drawing by hands: special pigment is applied to the surface of the Xuande porcelain in the manner of hand-drawing to obtain a colored porcelain body, wherein during hand drawing, water is added to the special pigment and the water and the special pigment are then mixed uniformly, and the water addition amount is determined according to the degree of the color in the drawn pattern; and d, firing the finished product: the colored porcelain body is subjected to biscuit firing for 35 to 45 minutes and then glaze firing for 35 to 45 minutes to obtain the finished product. The calcareous porcelain product produced by the hand-drawing production method has the advantages of fresh picture, rich colors, sufficient representation of hierarchy, the representation style of Chinese painting, smooth and transparent glaze, strong picture three-dimension effect and good decorative effect.

Description

technical field

[0001] The invention provides a production method of ceramics, especially a production method of calcareous porcelain. Background technique

[0002] In the production methods of calcareous porcelain such as bone china and shell porcelain, due to the material characteristics of calcareous porcelain raw materials, the two-firing process of high-temperature plain firing and low-temperature glaze firing is generally adopted. And molding is difficult, and firing pass rate is low. And it is difficult to adopt hand-painted decoration on the bisque body, prone to stroke defects or incomplete and uneven color development, blurred or faded pictures, therefore, it is not yet possible to use the in-glaze production method on calcareous porcelain. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide a production process of calcareous porcelain in-glaze hand-painting, so as to improve the decorative effect. [000...
