Porcelain is a high-end, elegant ceramic product widely used in home furnishings, dining, and ceremonial purposes. It not only boasts beautiful shapes, rich patterns and colors, but also high practical value. Among its components, the glaze is crucial in determining its surface smoothness, texture, and cleanliness.
Porcelain tableware glazes are generally made from inorganic compounds as raw materials, processed through a series of steps. Below are some common glaze types and formulas:
Transparent Glaze: Primarily composed of raw materials such as quartz, feldspar, and calcium carbonate in varying proportions. The main characteristics of transparent glazes are their clarity, smoothness, and pure color, making porcelain more luminous and beautiful.
Blue Glaze: A cobalt-based glaze that gives porcelain a deep blue, light blue, or bluish-white appearance. Blue glazes are mostly high-temperature resistant, significantly improving the high-temperature resistance of porcelain.
Multi-colored Glaze: Multi-colored glazes are typically made by adding a certain proportion of metal oxides (such as chromium, manganese, iron, etc.) or minerals (such as garnet, pyrite, etc.) to a base glaze. Multicolored glazes can make porcelain more colorful and varied.
The Influence of Glazes on the Processing and Properties of Porcelain Different types and formulas of glazes have different effects on the processing and properties of porcelain. For example, transparent glazes can make the surface of porcelain smooth, translucent, and soft, but they are not stain-resistant or wear-resistant. Blue glazes, on the other hand, can make porcelain resistant to stains, wear, and acids, but the surface texture is slightly rough. Multicolored glazes not only allow for diverse color variations on the surface of porcelain, but also enhance the surface texture and artistic appeal.
