Problems solved by technology

[0008]The above-mentioned patents are mostly two-firing process, only CN02136786.8 patent proposes to use three-time firing, but the proposed color firing still uses 700-800°C Medium-temperature color firing, while glaze firing uses high temperature, which is prone to the problem of heavy metal overflow during glaze firing, which is not conducive to the production of high-grade underglaze color ceramics

Embodiment 1

[0032] A decoration method for high-grade underglaze color ceramics, which is produced by three-firing method. Firstly, the green body is bisque-fired, then color-fired, and finally glaze-fired; The three-firing method of firing, high-temperature color firing and bottom-temperature glaze firing is used to make underglaze colored ceramics; the specific manufacturing process steps are as follows:

[0033] 1. Blank making: refining the raw materials for making underglaze color ceramics into mud blanks, and then making blanks of the required shape according to needs;

[0034] 2. High-temperature biscuit firing: place the formed biscuit in a biscuit sagger for firing; the bisque firing is to put the prepared biscuit in a sagger with a cover, and fasten the sagger cover so that The biscuit is in a closed state in the sagger; then the sagger with the biscuit is placed in the bisque firing furnace, and bisque firing is carried out at a temperature of 1250°C;

Abstract

The invention discloses a high-grade ceramic underglaze color manufacturing and decorating method. The underglaze color is manufactured in a three-time firing mode. The method comprises the following steps: performing biscuit firing on the green body, performing colored firing, and finally performing glaze firing; the method is characterized in that according to the three-time firing mode, the underglaze color ceramics are manufactured by virtue of a three-times firing method comprising high-temperature biscuit firing, high-temperature colored firing and low-temperature glaze firing, wherein the high-temperature biscuit firing is performed under the temperature condition of 1150-1250 DEG C; the high-temperature colored firing is performed under the temperature condition of 1000-1250 DEG C; and the low-temperature glaze firing is performed under the temperature condition of 1000-1140 DEG C.

Description

technical field [0001] The present invention relates to an improvement on a traditional ceramic technology, in particular to an improvement in the manufacturing process of oxidizing flame and reducing flame underglaze for medium and high temperature ceramics, which can be applied to oxidizing flame and reducing flame glaze for medium and high temperature ceramics Under-glaze color manufacturing is an innovation in the production process of under-glaze color ceramics. Background technique: [0002] Underglaze color is a kind of porcelain glaze decoration, also known as "kiln color". The underglaze color is mainly to draw various decorations on the formed and dried biscuit (ie semi-finished product) with pigments, and then cover it with white transparent glaze or other light-colored surface glaze, and then burn it in a kiln at high temperature (1200-1400°C) once. become. After firing, the pattern is covered by a layer of transparent glaze film, the surface is bright and sof...
