Traditional Ceramics

  • Ball clay, China clay, Feldspar, Silica, Dolomite, Talc, Calcite and Nepheline are the common materials used for most of the ceramic products. Each raw material contributes a certain property such as dry strength, plasticity, shrinkage, etc. to the ceramic body. Therefore, by careful selection of materials, desired properties are acquired for the final output. Powder preparation is a major consideration in the ceramic industry. Surface area, particle size and distribution, particle shape, density, etc. each have their own effect on production. Powder has to be prepared to meet required particle size, particle shape, and other requirements for a particular industry. Milling is done to get the desired particle size. Unlike in the ,advanced ceramics industry the purity of ceramic powder is not an issue in traditional ceramics.

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...
