Description

Ceramic glazing process

Technical Field

The invention relates to the technical field of ceramic glazing, in particular to a ceramic glazing and coloring process.

Background

The porcelain is an article which is composed of porcelain stone, kaolin and the like and is provided with glaze or colored drawing on the surface. The porcelain is formed by being fired in a kiln at high temperature (about 1280-1400 ℃), and the glaze color on the surface of the porcelain is changed chemically due to different temperatures at the earliest generation in middle and late stages. The sintered porcelain body generally contains less than 3 percent of iron element, is impermeable, and is widely used by people all over the world due to the characteristics of lower cost, wear resistance and impermeability. Porcelain with high raw material purity can generate crisp sound similar to metal collision when colliding with each other. The high-grade porcelain has the manufacturing process difficulty which is far higher than that of the common porcelain, so the collection of the exquisite porcelain in the ancient royal rooms is not lacked.

Glazing is a method of firing a porcelain, in which a blank is fired, the blank is removed after firing, and then the blank is fired. A layer of vitreous enamel is coated on the fired blank, which mainly plays a role in protection and decoration. The traditional glazing method is to carry out hand-drawing after the biscuit firing is finished, and the produced patterns and colors have low fidelity and are difficult to change.
