I. Origins and Evolution
Porcelain, the pinnacle of ceramic art, originated in China over a millennium ago. As early as the Tang Dynasty (618–907 AD), Chinese artisans mastered the technique of combining kaolin with porcelain stone and firing the mixture at high temperatures to produce hard, white, and semi-translucent porcelain. During the Song Dynasty (960–1279 AD), porcelain-making techniques reached their zenith, giving rise to the renowned "Five Great Kilns"—Ru, Guan, Ge, Ding, and Jun—which epitomized the highest standards of porcelain craftsmanship at the time. The aesthetic appeal and practicality of porcelain made it a significant commodity in China's foreign trade, spreading along the Silk Road and gaining admiration worldwide.​

II. Scientific Foundations: Kaolin and Firing Techniques
The uniqueness of porcelain stems from its raw materials and firing processes. Kaolin, a white clay rich in kaolinite, offers excellent plasticity and refractory properties. Porcelain stone, abundant in feldspar and quartz, forms a glassy phase at high temperatures, enhancing the strength and translucency of porcelain. By mixing kaolin and porcelain stone in precise proportions and firing the blend at approximately 1300°C, the resulting porcelain exhibits hardness, density, whiteness, and semi-transparency. The physical and chemical transformations during this high-temperature firing process endow porcelain with low water absorption, high strength, and excellent thermal stability.

III. Craftsmanship and Techniques: Forming and Decoration
The production of porcelain involves meticulous and complex processes, primarily encompassing the following steps:​
Forming: Utilizing methods such as wheel throwing, slip casting, and molding to shape the clay into desired forms. Wheel throwing is suitable for symmetrical items like bowls, cups, and vases, while slip casting is ideal for creating intricate shapes.​
Drying and Bisque Firing: The shaped pieces are air-dried to a certain extent before undergoing bisque firing (typically at 800–900°C) to strengthen the body, facilitating glazing and decoration.​
Glazing and Decoration: Applying glaze to the bisque-fired pieces, with glaze formulations tailored to achieve various colors and textures. Decorative techniques include underglaze painting, overglaze painting, carving, and stamping.​
Glaze Firing: The glazed items are subjected to a second high-temperature firing (around 1300°C), causing the glaze to melt and fuse with the body, resulting in a smooth and durable surface.​

IV. Cultural Significance: Identity, Art, and Exchange
Porcelain serves not only as functional ware but also as a vessel of rich cultural connotations:​
Symbol of Status: Historically, porcelain was often a symbol of power and status. Imperial porcelain reflected royal authority, while in the civilian realm, porcelain represented wealth and taste.​
Artistic Expression: Porcelain provides a medium for artists to convey thoughts and emotions. From traditional blue-and-white and pastel wares to contemporary installations, porcelain showcases boundless creativity and aesthetic appeal.​
Cultural Exchange: As a vital export in ancient China's foreign trade, porcelain facilitated cultural exchange and integration between China and other civilizations. Europe's "porcelain craze" spurred the development of local porcelain industries, such as Germany's Meissen porcelain.​
