The fascinating world of ceramics
I have to admit I knew very little about the ceramic industry when I was tasked with creating an article for a manufacturer of vibrating screens & sieves; industrial agitators and mastelli; electric pumps for the ceramic industry; magnetic iron removers & filters; and products for companies that are specialised in industries where materials screening is required. However, it turns out that this is a large and fascinating subject.
The English word ‘ceramic’ comes from the ancient Greek word for ‘potters’ and ‘potter’s clay’ and is a solid material comprising of inorganic compounds – metal, non-metal or metalloid atoms primarily held in ionic and covalent bonds. The most common examples of ceramics are earthenware, porcelain, stoneware, bone china, and brick. The earliest known ceramics made by humans were pottery objects such as pots, vessels or figurines made from clay. Later ceramics were glazed and fired to create smooth, coloured surfaces, to decrease porosity. Ceramics are now used throughout the world in countless domestic, industrial and building applications as well as in art. In modern times, newer ceramic materials have been developed for use in advanced ceramic engineering, such as in semiconductors.
The discovery of ceramics from archaeological digs provides a lot of very important information helping us to understand historical cultures, ancient technology and the behaviour of ancient civilisations. They are a very common artefacts found at arachnological sites among the most common artefacts to be found and are generally found as fragments or chards of broken pottery. By analysing these fragments and shards, it’s possible to distinguish between different cultural styles providing invaluable historical information about peoples from the past.
Ceramic art is also a fascinating subject and these items take many forms such as pottery, tableware, figurines, and sculpture. We have evidence of a long history of ceramic art in almost all developed cultures, and often ceramic objects are all the artistic evidence left from vanished cultures. Examples of ancient, vanished cultures include the Nok who lived in Africa over 2,000 years ago, the Nabateans who existed from around 312 BC, the Clovis people who lived in the deserts of New Mexico around 9000 years ago, and the Catalhoyuk, a very old Neolithic civilization who lived where modern-day Turkey now stands from 7500 to 5700 BC, living in mud-brick housing similar to other extremely early civilizations – they seem to have disappeared around 8000 years ago. Much can be learned from these early cultures by examining ceramic fragments they left behind.
In the modern world, the production of ceramics for all domestic and industrial applications has mainly been industrialised (besides the production of art) and there is a whole industry built up around the production of machinery and associated maintenance supplying this industry. An example of one of these companies is Bi technology who produce vibrating screens & sieves; industrial agitators and mastelli, electric pumps for the ceramic industry, and magnetic iron removers and filters. This Italian company specialise essentially in all those industrial departments where materials screening is required.
