Porcelain has a history: In China, porcelain was made during the Tang Dynasty using a firing process with two ores: feldspar and kaolin. This process has undergone some changes over the centuries. Today, porcelain ceramic is made from the raw materials kaolin, feldspar, quartz, and clay. It differs from other ceramic products by the presence of three unique and fundamental technical properties. These are hardness, whiteness, and translucency. Porcelain has high mechanical strength, low porosity, and high density, giving it durability, harmlessness, a soft feel, and beauty in everyday use. Porcelain is created by higher firing temperatures and is largely insensitive to temperature fluctuations - it is fired at up to 1400°C, making the material robust. Each piece of porcelain undergoes a process of designing, composing, shaping, drying, decorating, and firing, resulting in tangible quality.
