Problems solved by technology

[0002] The firing process of traditional painted pottery in my country is mostly fired at low temperature, while black pottery is fired with carburizing technology. The so-called black pottery is carburized technology, while painted pottery is fired with low-temperature transparent lead glaze. The material is all made of yellow clay, and the firing temperature is around 850°C to 960°C. The fired pottery and black pottery products are not high in hardness, poor in usability, and have a single shape and color, which cannot satisfy According to the needs of the existing market, by combining black pottery and painted pottery, coupled with the contrast of the combined colors, it gives people a strong contrast of colors and visual impact, which greatly improves the artistic effect of the combination. How to combine the two Effective combination is a technology that needs to be solved

Embodiment 1

[0018] A firing process that combines traditional painted pottery with black pottery. After the yellow clay is crushed into powder, water is added to the powder to make a slurry. After filtering and sedimentation, the embryo body of the desired shape is made, and then the embryo body is Biscuit firing at 680°C for 3 hours, then naturally cooled to room temperature, and then partially glazed, the glaze slurry was evenly applied to the surface of the green body, fired at 1050°C for 3 hours, and then evenly coated with nano-graphene on the surface of the green body Modified vegetable oil, fired at 700°C for 8 hours, cooled naturally to room temperature;

[0019] The glaze slurry is made of the following components in parts by weight: acid-activated kaolin 15, clay 22, quartz 16, montmorillonite 14, feldspar 13, water muscovite 14, and cement 4.

[0020] Further, the particle size of the powder is 150 mesh.

[0021] Further, water is added to the powder, and the amount of water a...

Abstract

The invention discloses a firing technology combining traditional colored pottery with black pottery, and relates to the technical field of pottery firing. The firing technology comprises the following steps: crushing yellow cement into powder, adding water to the powder, blending the powder into slurry, preparing the slurry into a blank body with a required shape after filtering and precipitation, performing biscuit firing on the blank body at 680 to 720 DEG C, naturally cooling the blank body to room temperature, performing local glazing, uniformly applying glaze slurry to the surface of theblank body, performing firing at 1050 to 1200 DEG C, uniformly applying nano graphene modified vegetable oil on the surface of the blank body, and performing firing at 700 to 800 DEG C, so as to obtain a ceramic product. The firing technology ensures that the hardness of the obtained ceramic product is obviously improved by effectively combining the processing technologies of colored pottery andblack pottery.
