Ceramic materials are special because of their properties. They typically possess high melting points, low electrical and thermal conductivity values, and high compressive strengths. Also they are generally hard and brittle with very good chemical and thermal stability. Ceramic materials can be categorized as traditional ceramics and advanced ceramics. Ceramic materials like clay are categorized as traditional ceramics and normally they are made of clay, silica, and feldspar. As its name suggests, traditional ceramics are not supposed to meet rigid specific properties after their production, so cheap technologies are utilized for most of the production processes.

Short about Ceramic Design The Master’s degree programme in Ceramic Design is a specialisation in the use of silica-based materials such as clay, concrete, plaster and glass as ceramic materials in various professional contexts. The overall objective of the programme is to prepare students for careers as ceramic designers through independent specialisation in relation to research, artistic research practice and in relevant practical and professional contexts. The objective of the programme is to expand the student’s understanding of specific ceramic materials and working processes on the basis of their own chosen specialisation, and further to support the development of their personal artistic profile under the guidance of the programme’s teachers.

What are ceramics used for? The interesting question is why ceramics behave like this—and the no-less-interesting answer boils down to materials science : it's all to do with how the atoms inside are bonded together. That explains how most materials work In metals, for example, atoms are relatively weakly bonded (which is why most metals are fairly soft); their electrons are shared between them in a kind of sea that can "wash" right through them, which is (simplistically speaking) why they conduct electricity and heat . A material like rubber , on the other hand, is made of long-chain molecules (polymers) that are very weakly attached to one another; that's why raw, white, latex rubber is so stretchy and why black, vulcanized rubber (like that used in car tires) is harder and stronger, because heat-and-sulfur treatment makes strong cross-links form between the polymer chains, holding them tightly together. All the electrons are locked up in bonds of various kinds (...

Types of ceramics Traditional ceramics Bricks, pottery, glass, porcelain, tiles, cement, and concrete are our classic, time-tested ceramics. Although they all have different uses, we can still think of them as general-purpose materials. Take tiles, for example. We can put them inside our homes or outside; on the walls, the floors, or the roof; and we can stick glass in our windows or poke away at it on our smartphone screens—we can even drink champagne out of it. Ceramics like this are ancient materials—ones our ancestors would recognize—that have gradually found more and more uses as the centuries have worn on. Advanced engineering ceramics By contrast, advanced ceramics are ones that have been engineered (mostly since the early 20th century) for highly specific applications. For example, silicon nitrides and tungsten carbides are designed for making exceptionally hard, high-performance cutting tools—though they do have other uses as well. Most modern engineered ceramics a...
