Problems solved by technology

[0004] The preparation process of Jianzhan is difficult to master, and the yield rate is low. For example, if the firing temperature is too high, the body of Jianzhan will easily have defects such as blistering and deformation, which will easily lead to flow glaze sticking to the bottom. If the firing temperature If it is too low, it will make it difficult to form glaze and markings
The preparation process of Jianzhan is relatively harsh. If the screening of Jianzhan components and the control of the preparation process (such as firing temperature) are not clear during the preparation of Jianzhan, it is difficult to produce a good glaze, which often leads to the number of pinholes on the glaze surface. Many, affect the appearance

Embodiment 1

[0055] The preparation process of the black-bottom gold-leaf Jianzhan comprises steps:

[0056] (1) Provide green body raw materials, glaze slurry and gold leaf raw materials, among which,

[0057] The green body raw material is prepared by the following method: 7 parts by weight of laterite (the laterite is taken from Nanshan Village, Shuiji Town, Jianyang District, Nanping City, Fujian Province, and includes the following components by weight percentage: SiO 2 50.25%, Fe 2 o 3 14.56%, Al 2 o 3 18.56%, the remainder is trace elements) and 3 parts by weight of kaolin (kaolin is taken from Jianyang District, Nanping City, Fujian Province, and includes the following components by weight percentage: SiO 2 45.32%, Al 2 o 3 38.69%, H 2 O 10.56%, the remainder is trace elements) mixed, added water, stirred for 5.5 hours, stood still for 8 days, passed through a 100-mesh sieve, precipitated, bagged for water filtration, smelted, and stale to obtain the green body raw mater...

Embodiment 2 and Embodiment 3

[0074] Jianzhan is very sensitive to the parameters of the preparation process, and a small change in the process parameters will have a great adverse effect on the appearance and other characteristics of the final product of the Jianzhan, and even lead to the failure of the preparation of the Jianzhan. Therefore, the requirements for the preparation process of Jianzhan are very strict. . Example 2 and Example 3 prepared the black-bottomed gold-leaf Jianzhan according to the same preparation process as in Example 1, and the properties of the Jianzhan prepared in Example 2 and Example 3 were basically the same as those of the black-bottomed gold-leaf Jianzhan prepared in Example 1 Similarly, the results show that the yield of Jianzhan prepared by the preparation process of Example 1 is high, and the method has good repeatability, strong stability, and is easy for large-scale production.

[0075] In the process of preparing the black background gold leaf Jianzhan, the inventor h...

Abstract

The invention discloses a preparation process for a black bottom gold leaf Jianzhan. The process comprises the following steps: providing a blank raw material, glaze slip and a gold leaf raw material;throwing and correcting the blank raw material and biscuiting the same to obtain a blank; applying the glaze slip to the blank to obtain the glazed blank; putting the glazed blank into an electric furnace kiln to be roasted to obtain a plain zhan; attaching the gold leaf raw material to the inner wall of the plain zhan; and then putting the plain zhan into the electric furnace kiln to be roastedto obtain the black bottom gold leaf Jianzhan. The black bottom gold leaf Jianzhan is black and moist in glaze, free of pores and smooth, the gold leaf is clear and visible and dazzling in color, andthe appearance is very graceful. Meanwhile, the gold leaf and the black bottom plain zhan are integrated, and the black bottom gold leaf Jianzhan touched by hands is free of coarse feeling.

Description

technical field [0001] The invention relates to the technical field of porcelain, in particular to a preparation process of a black-bottom gold-leaf Jianzhan. Background technique [0002] Jianzhan is a bright pearl in the history of Chinese ceramics. The craftsmanship of Jianzhan is particularly exquisite, and it has a unique beauty compared to other porcelains. [0003] Jianzhan is very sensitive to the preparation process, and small changes in process steps or parameters will also have a great adverse effect on the appearance and other characteristics of the final product of Jianzhan, and even lead to the failure of Jianzhan firing. Therefore, the selection of preparation process steps and parameters And optimization has a great influence on the production of Jianzhan. [0004] The preparation process of Jianzhan is difficult to master, and the yield rate is low. For example, if the firing temperature is too high, the body of Jianzhan will easily have defects such as bli...
