Ceramics is the art and science of making objects from inorganic, nonmetallic materials that are permanently hardened by heat. The term derives from the Greek word keramos, meaning pottery or burned stuff, and the discipline encompasses everything from ancient earthenware vessels to advanced technical ceramics used in aerospace engineering. Ceramic materials are formed by shaping clay or other raw materials while pliable, then firing them in a kiln at temperatures ranging from about 600 degrees Celsius to over 1700 degrees Celsius, which triggers irreversible chemical and physical changes that transform soft, fragile greenware into hard, durable objects.
The history of ceramics stretches back at least 26,000 years to the earliest known fired clay figurines, such as the Venus of Dolni Vestonice. Functional pottery emerged around 20,000 years ago in East Asia, making ceramics one of humanity's oldest technologies. Major historical milestones include the development of earthenware in the Neolithic period, stoneware in ancient China, porcelain during the Tang and Song dynasties, and the industrial manufacture of technical ceramics in the modern era. Every major civilization has contributed distinctive ceramic traditions, from Greek black-figure and red-figure ware to Japanese raku, Islamic lusterware, and Mexican Talavera.
Today, ceramics spans two broad domains. Studio and traditional ceramics remain a vibrant fine art and craft, with practitioners exploring wheel throwing, hand building, slip casting, and sculptural techniques. Meanwhile, advanced technical ceramics play critical roles in electronics, medicine, energy, and defense. Ceramic materials such as alumina, zirconia, silicon carbide, and piezoelectric ceramics are indispensable in semiconductors, dental implants, cutting tools, body armor, and space shuttle thermal tiles. Understanding ceramics therefore requires knowledge of chemistry, materials science, geology, art history, and hands-on craft skill.
