Bone china can be divided into over-glaze, mid-glaze, under-glaze, colored glaze and uncolored white porcelain according to the characteristics of the flower surface.

On-glaze color is a product made by sticking decal paper made of on-glaze ceramic pigments on the glaze or directly painted on the surface of the product with pigments, and then baked at 700-850°C. Because the firing temperature did not reach the melting temperature of the glaze layer, the flower surface did not sink into the glaze, but only adhered to the surface of the glaze layer. The gloss of the decorative pattern was significantly different from the gloss of the glaze. If you touch it with your hands, the surface of the product will feel uneven.

The decoration method of the in-glaze color is the same as the over-glaze color, but the baking temperature is higher than that of the over-glaze color, reaching the melting temperature of the ceramic product glaze. The ceramic pigment sinks into the glaze when the glaze is melted, and is covered by the glaze layer after cooling. , The gloss of the decorative pattern is consistent with the gloss of the glaze. The surface of the product is smooth as glass without obvious bumpy feeling when touched by hand.

The decoration of the underglaze color is carried out on the mud blank, and is fired at a high temperature after glazing. This product is the same as the in-glaze color, the decorative pattern is covered by the glaze layer, and the luster of the decorative pattern is consistent with the luster of the glaze surface.

Color glaze porcelain adds a high-temperature color agent to the ceramic glaze to make the glaze surface of the fired product show a certain color, such as yellow, blue, and bean-green.

White porcelain usually refers to ceramics without any color decoration.

Different decoration methods bring different decorative effects. The decorative effects of overglaze products are bright and colorful. In-glaze products and underglaze products are generally simple and elegant, and the color is not as gorgeous as overglaze products. Everyone can Choose products with different decoration methods according to your own preferences.
