Basically, they can be classified into two: metallic and non-metallic. Furthermore, the metallic ones can be subdivided into ferrous and non-ferrous metals, while the non-metallic ones can be divided into natural and synthetic materials.</p> <p><img class="size-full wp-image-19706 aligncenter" src="https://classhall.com/wp-content/uploads/2018/06/properties-of-materials.jpg" alt="Properties of materials" width="600" height="175" /></p> <p> </p> <h2>The Definition of Wood</h2> <p>One of the materials that is supplied by nature is wood. Wood is commonly used in some engineering manufacture because it is light, strong and can be worked upon easily.</p> <p>Wood is a material obtained from trees. It is made up of cellulose and lignin each consisting of 60% and 28% respectively.</p> <p> </p> <h2>Identification of Wood</h2> <p>Generally, wood has very good combination of colours to give it high decorative value. This makes it possible to identify some woods by their colour. Examples are:</p> <p></p>

When it is wet, it can easily be molded into different shapes and sizes. We use clay to mould various objects like storage pots, cooking pots and dishes.</p> <p>We use mud to construct support for cooking pots, to build houses and also to make bricks for building houses. We make cement blocks that we use for building houses by mixing sand and cement to get typical shape. All the above solid objects made from clay, mud or cement are called ceramics.</p> <p>Ceramics break easily when dropped. We say they are brittle; this differentiates ceramics from metals, plastics, wood and rubber. Ceramics are less dense than most metals. They have high melting points.</p> <p>They are a very large group and have very wide uses such as:</p> <ol> <li>Refractory ceramics (high temperature bricks) for furnaces and flue linings.</li> <li>Tiles, such as roof tiles, glazed and unglazed floor and wall tiles, including white tiles.</li> <li>Sanitary fittings of all kinds usually known as white ware</li> <li>Common brick to high grade engineering brick used for the construction of machinery bases. Basically, they are of:</li> </ol> <p style="padding-left: 40px">(a) Structural clay products, including common bricks and sewer bricks. These products are dried and fired for strength after being made from a mixture of clay and shale.</p>
