The magical glazing of ceramics - Industry Trends and Best Practices

There are two types of glazing: full-body glazing and glazing on the outside of the vessel. Full-body glazing is mostly used for small objects. For large objects, the inner glaze is usually applied first, followed by the outer glaze. This is because once the glaze layer is absorbed by the body, it quickly dries into powder and cannot be touched anymore; otherwise, the glaze layer will be damaged and the glaze will come off after firing.

Before applying the outer glaze, it is necessary to ensure that the inner glaze is basically dry so that the body can regain its water absorption and fully absorb the glaze slurry. After the inner glaze is dry, hold the appropriate part of the body with both hands. First, rinse the bottom with water to reduce excessive glaze absorption at the bottom. Then, press the body firmly to immerse it in the glaze jar. During the glazing process, pay attention to keeping the glaze slurry surface level with the mouth of the body. Do not let the glaze slurry overflow the edge of the mouth and flow into the interior of the body, which may cause uneven glazing.Glazing is a continuous process, and the duration is determined by the size and thickness of the body. Generally, it takes 10 to 20 seconds or even longer. After glazing is completed, rotate the body a little to make the glaze absorption more uniform.

A method of glazing the interior of objects, often used for deep-bellied and small-mouthed shaped bodies such as jars and bottles.Use a spoon or measuring cup to pour the glaze slurry into the body, about half of the inner space. Then shake it at a constant speed to evenly coat the glaze slurry on the inner wall of the vessel. If the object is too large, two people need to cooperate to complete it, and their movements should be synchronized. The inner glaze generally does not need to be too thick. After visually reaching the required thickness, the remaining glaze slurry is poured out and the glazing is completed.

Brushing glaze, also known as "applying glaze", involves dipping a brush in glaze slurry and applying it to the body. It was first seen on primitive celadon. It is mostly used for local glazing and supplementary glazing on irregular shapes or at the mouth, shoulder, bottom and other parts, or for applying several different glazes on the same body.

Spray glazing, also known as blown glazing, is used to increase the thickness of the glaze layer and make up for the limitation of glaze absorption by the body during the immersion glazing process. When glazing, place the body on a turntable or a glazing blowing table. While rotating the turntable at a constant speed, directly spray glaze with a glazing blowing pot. Do not spray glaze again until the previous glaze surface is basically dry.

Glazing can create a special effect of fluidity and is an early glazing method, represented by Tang Sancai. By applying several types of colored glazes on the same body, or by using the splashing method, or by varying the thickness of the glaze layer, or by pouring ground porcelain stone particles onto the glaze surface, a unique charm is created.

It is mostly used for flat blanks such as plates and discs. Place it on the turntable, and pour the glaze onto the center of the body with a bowl or spoon. Under the action of centrifugal force, the glaze slurry spreads evenly, making the thickness of the glaze on the body uniform. The excess glaze slurry is thrown out. Strictly speaking, wheel glaze falls within the category of pouring glaze.
