Ceramic tea cup manufacturing process

Ceramic tea cup manufacturing process

The so-called ceramic tea cup is the cup made of clay. This kind of cup is exquisite in shape and rich in design, which is favored by the majority of consumers. Let's have a detailed understanding of the production process of ceramic cups.

1. Mud training: from the mining area to take porcelain stone, after water duichun fine, washing, remove impurities, precipitate into brick-like clay. Then mix the mud with water, remove the slag, rub by hand, or trample by foot, squeeze out the air in the mud, and make the moisture in the mud even.

2. Billet: the mud thrown in the pulley wheel center, with the method of flexor extension to draw out the rough shape of the body.

3. Blank: The appearance of the impression is rotary cut according to the internal arc of the blank. The blank that is dried to half dry is overlaid on the mold, and the blank is patted evenly on the external wall, and then demold.

4. Billet: the billet is covered in the pulley pulley on the barrel, turning the wheel, with a knife spin cutting, in the billet body thickness is appropriate, the surface is clean, this is a process of high technical requirements.

5. Drying: the processed billet is placed on the wooden frame to air.

6. Engraving: use bamboo, bone or iron cutting tools to carve out patterns on the dried or semi-dried blank body.

7. Glazing: common round mouth by dipping glaze (the billet into glaze bowl, a time along with glaze flush immediately offered) or swing glaze, the glaze slurry injection shaking inside billet, make up and down or so even glaze, then quickly away excess slurries), cut (relative to "circular unit", "round device" means by throwing method of forming the circular vessels, such as bowl, plate, plate, etc. And the forming process of more complex vessels, such as bottles, statue, pot, pot, etc., is called "cut ") or large round utensils with blowing glaze (the method is to cover the bamboo tube with fine yarn, dip in the glaze after blowing with the mouth, so repeated for many times, the blank surface can be uniform thickness of the glaze layer).

8. Kiln firing: The time course is about one day and night, and the temperature is about 1300℃. First LAY THE KILN DOOR, FIRE THE KILN, FUEL IS PINE WOOD, pile technical guidance, measure the fire, master the change OF kiln temperature, decide the ceasefire time.

9 color glaze: glaze color such as colorful, pastel, etc., is in the enamel has been burned into the porcelain pattern, fill color, and then into the red furnace to low temperature baking, the temperature of about 700℃- 800℃. In addition, before the kiln is painted on the billet body element fetus, such as blue and white, youligong, it is called youligong, its characteristic is color under high temperature glaze, never fade.
