Embodiment Construction

[0019] The method for underglaze multicolored decoration of bone china is characterized in that: according to the following technological process:

[0020] 1) After the green body is formed and dried, carefully repair it and remove the burrs;

[0021] 2) Carry out low-temperature bisque firing. At this stage, set the firing temperature to 800-900 degrees Celsius to dry the green body to increase the strength of the green body;

[0022] 3) The green body after low-temperature bisque firing must be further modified, polished, cleaned and dried;

[0023] 4) After cleaning and drying, the low-temperature biscuit is used for color decoration;

[0024] 5) The decorated low-temperature biscuit is fired into the kiln to fix the color. This firing is the second firing, which is a high-temperature bisque firing. The temperature setting: 1200 degrees Celsius to 1250 degrees Celsius;

[0025] 6) After the high-temperature biscuit body comes out of the kiln, it is carefully sorted, clean...

Abstract

The invention discloses a method for underglaze five-color decoration of bone china. The method is characterized by comprising the following procedures: 1) molding and drying a green body; (2) carrying out low-temperature biscuiting; (3) carrying out further finishing, polishing, cleaning and drying on the green body having undergone low-temperature biscuiting; (4) carrying out color decoration ona cleaned and dried low-temperature biscuit; (5) putting the low-temperature biscuit having undergone color decoration into a kiln for firing and color fixation; and (6) putting the glazed high-temperature biscuit into a high-temperature kiln for third firing, wherein the sintering is low-temperature glaze firing and a sintering temperature is set. The bone china disclosed by the invention is crystal clear and elegant in color and has unique underglaze five-color decoration.

Description

technical field [0001] The invention belongs to the technical field of ceramic underglaze decoration, in particular to a multicolored decoration method for bone china underglaze. Background technique [0002] Underglaze multicolored is a traditional ceramic decorative art with a history of more than 110 years. The traditional underglaze color was first created in Liling, Hunan. The traditional production process basically adopts "three-firing", that is: firstly, the green body that has been shaped and dried but has not been glazed is bisque-fired at low temperature, and then painted, and then the bisque fired body after the color decoration is subjected to a second low-temperature bisque firing ( The so-called solid color), and finally glazed into a high-temperature kiln, fired in an atmosphere of oxidation and then reduction. The modern underglaze multicolored firing process has been improved, and most of them have been fired twice. However, these production processes are ...
