Problems solved by technology

The first type is over-glaze color or under-glaze color, which is easy to peel off and lose color, and it is only through colored glaze without painting, so it cannot show the gradual change of local color; the second type is under-glaze multicolored as the background, supplemented by Underglaze blue and white, embossed and gold-painted techniques, while the embossed is only partially presented with embossed dots, which cannot express the overall three-dimensional effect of the finished product, and the pattern cannot show the gradual change of local colors, and the decoration layer is single

Embodiment 1

[0042] A manufacturing process of three-dimensional underglaze multicolored ceramics, comprising the steps of:

[0043] 1) Biscuit firing: Use selected ceramic raw materials to make a slurry after ball milling and sieving, and mold the mold into the required shape to make a green tire, and then perform biscuit firing at 800°C for the formed green tire , get the green body;

[0044] 2) Biscuit engraving: use the digital engraving machine to carry out precise engraving on the biscuit, use a series of tools in the machine software such as stamping, stacking, material removal, polishing, and single-line embossing to select appropriate processing strategies and tools to generate knives The road traces are carved to create a layered and three-dimensional picture, which is completed with the aid of metal knives to carve a three-dimensional and multi-layered plain picture;

[0045] 3) Biscuit color painting: Using the ink-splashing technique, use a splash-ink pen to dip high-temperat...

Abstract

The invention relates to a manufacturing technique of stereoscopic underglaze multicolor ceramic, which comprises the following steps: carrying out ball milling on a selected ceramic raw material, screening, slurrying, carrying out injection forming on a mold to obtain a required shape, preparing a blank, and carrying out bisque firing to obtain a biscuit; carving out a stereoscopic multilayer plain color picture on the biscuit with a carving tool; dipping a drawing tool into underglaze multicolor pigments, and drawing and decorating on the stereoscopic picture of the biscuit to obtain a colored biscuit; carrying out color depth gradation treatment on the picture of the colored biscuit by using a special brush; and covering a glaze layer on the surface of the colored biscuit subjected to color treatment; and firing the glaze-covered colored biscuit in a kiln again to obtain the finished product. The technique adopts the two modes of biscuit carving and mold carving. The ceramic article prepared by the technique has the advantages of strong stereoscopic effect, abundant colors, high color layering effect and glossy and bright glaze.

Description

technical field [0001] The invention relates to a manufacturing process for the surface of ceramic products, in particular to a manufacturing process for three-dimensional underglaze multicolored ceramics. Background technique [0002] my country is the first country in the world to make porcelain. In the course of thousands of years of development, ceramics have not only played the role of containers, but also played the role of decoration. Therefore, the decoration methods of ceramics are also improving day by day. There are three main methods of ceramic decoration: tire decoration, glaze decoration and color decoration. [0003] Carcass decoration is mainly a decorative method to beautify the ceramic carcass by using sculpture, pasting, engraving, hollowing out, color tires, etc.; glaze decoration is to spray various glazes of different colors to cover the carcass, beautify the utensils, Dehua white porcelain and Longquan celadon are more famous for glaze decoration. C...
