Ceramic production process
1.Milling 练泥
Various raw materials including feldspar, silica, clay and pottery stone are mixed and fine-milled in the ball
mill.
2.Filter press & Vacuum extrusion 摞泥
The clay body is made by filter pressing the slip. The pressed body deaired and extruded to the required
size through the pug mill.
3.Green Making 制坯
Using appropriated roller head and plaster mould, green body is formed.
For the irregular shapes such as teapots and figurines, slip casting is used.
In casting, liquid clay (slip) is poured into plaster moulds and the
green shape forms on the mould as the water is absorbed through the plaster mould.
4.Finishing 修坯
The rough edges and foot of the green ware are cleaned with wet sponge by automatic edge-cleaning machine or by skilled hand.
5.Glazing 上釉
To seal the surface of the biscuit body and to give the product its glossy finish, glaze is applied using automatic
glaze spraying line.
6.Glost firing 烧釉
Carefully loading the glazed ware onto a kiln car, the glazed ware is fired at 1280°C.
At the temperature, the glaze powder melts and turns into a transparent glass layer covering the biscuit
body. The glost-fired ware is inspected and ready for the decoration.
7.Decaling 贴花
The printed decal is transferred onto the glost ware and dried.
8.Decoration(decal) firing 烤花
The decal and the ware are fired at appropriated temperatures and the printed patterns permanently fuse onto
the glaze layer to give permanent durable decoration.
9.Inspeciton & Packaging 修整成箱
Experienced eyes in the inspection area checks for possible faults in the ware and the finished ware is
packaged as necessary.
