Posliinia

Posliinia, also known as porcelain, is a fine ceramic material prized for its whiteness, translucency in thin sections, and relative strength. A porcelain body is typically made from kaolin (china clay) with fluxes such as feldspar and sometimes quartz. When fired at high temperatures, roughly 1200–1400°C, the components fuse into a dense, glassy matrix that yields a hard, durable substance capable of a smooth, glass-like glaze.

Originating in China, true porcelain was developed during the early medieval period and achieved its mature form in the Song and Ming dynasties. Jingdezhen emerged as a major production center, producing wares that became highly valued across Asia and later Europe. Porcelain reached Europe in the 17th and 18th centuries, where it spurred technological and artistic efforts, including the establishment of Meissen in Germany as the first European hard-paste porcelain producer. Other renowned centers followed, such as Sèvres in France and various Italian and British manufactories.

There are two broad types of porcelain. Hard-paste porcelain uses a body of kaolin and a higher-temperature glaze, resulting in a dense, often translucent material. Soft-paste porcelain, developed in Europe to imitate Chinese porcelain, uses a different recipe with glassy or soapstone-like components and is fired at slightly lower temperatures. A related subclass, bone china, incorporates bone ash and is known for a distinctive whiteness and lightness.

Manufacture involves processing raw materials, shaping (throwing, molding, or slip casting), air-drying, bisque firing, glazing, and a final glaze firing. Posliinia is widely used for tableware, decorative figurines, jewelry boxes, and tiles, valued for its aesthetic qualities and enduring durability.
