Introduction of ceramic manufacturing technology

Ceramic production technology: blank drawing, clay strip rolling and decal.

1, stretch forming

Using the centrifugal motion produced by the billet puller, the semi-cured cement-bearing material is stretched and formed according to the design concept during the rotation process. The biggest feature of making pottery with clay chips is that it is easy to form a large and complete surface and the molding speed is faster.

2, mud slab building

Mud dam method is a vegetable-making technology using mud dam construction. The mud stick can be rubbed by hand or squeezed by a mud stick pressing tool. Plain painting-painting with pigments on vases, bowls, plates, cans and other utensils (plain color). Plain firing: after the mud is dried, it is put into the kiln, and the secondary plain firing is carried out to about 800 degrees to harden the mud, and then it is cooled and taken out of the kiln.

3, decals

For example, if the bottle body needs other words such as trademarks, alcohol content or silk-screen patterns, the surface of the burned bottle body should be pasted with glaze decals, and then baked in the oven, about 700-800 degrees.

What should we pay attention to when making pottery?

1, alumina (calcined)-used for glaze matching and boron plate sand.

Inhalation may cause irritation. Wash your hands thoroughly after use.

2. Gray (all kinds of plant ash)-glaze raw materials.

This raw material combines with water to produce strong alkali, so plant ash should wear goggles and rubber gloves when dealing with water and salt.

3. Preparation of raw materials of barium carbonate (China, Germany)-clay and glaze.

It is irritating to eyes and nasal cavity, soluble, and contact will cause skin allergy. Avoid using on the surface that comes into direct contact with food.
