Brick

= ...A very useful material!=

====Bricks are made from [|clay], [|shale], soft slate, [|calcium silicate], concrete, or shaped from quarried stone, but clay is considered the most common material====

In 2007 a new type of brick was invented, based on [|fly ash], a by-product of [|coal power] plants.
====Bricks are used in [|masonry] construction, for building, [|pavement], as a decorative surface and in the [|metallurgy] and [|glass] industries for lining [|furnaces].====

==== **COMMON brick** is made of ordinary clays or shales and burned in the usual manner in the kilns. These bricks are not produced in any special color or surface texture. It is used for backing courses in solid or cavity brick walls. ====

**FACE bricks** are used in the exposed face of a wall and are higher quality units than backup brick. They have better durability and appearance. The most common colors of face brick are various shades of brown, red, gray, yellow, and white.



==== **GLAZED bricks** have one surface of each brick glazed in white or other colors. The ceramic glazing consists of mineral ingredients that fuse together in a glass-like coating during burning. This type of brick is particularly suited for walls or partitions in hospitals, dairies, laboratories, or other buildings where cleanliness and ease of cleaning are necessary. ====

==== **FIREBRICK** is made of a special type of fire clay that will withstand the high temperatures of fireplaces, boilers, and similar usages without cracking or decomposing. Firebrick is larger than regular structural brick, and often, it is hand molded. ====



**CORED BRICK** are made with two rows of five holes extending through their beds to reduce weight. There is no significant difference between

**Now let`s talk about the Bricklayers work!** ====Bricklayers are responsible for a variety of work. Typically it involves [|hands on bricklaying] like measuring the work area following the architect's plans, mixing mortar by hand or with a mechanical mixer, laying the bricks and applying the mortar, shaping and trimming bricks using bricklaying tools and checking that the brick wall is straight. ==== ==== Some bricklayers pick up their skills informally by watching others perform the work. However, most employers prefer to hire someone who has training or on-site experience. That’s way it's important to take the time to [|learn bricklaying techniques]. Individuals who learn on the job usually start as helpers or laborers and their duties involve carrying materials, moving scaffolds and mixing mortars. If the opportunity arises, they can learn from experienced bricklayers how to spread mortar, lay brick or set stone. The learning period for understanding bricklaying techniques is much longer this way than if trained in an Apprenticeship program or through a training course====

====If possible, a great way to get started in [|learning bricklaying] is through an Apprenticeship. The types of programs available will really depend on your local area and the job market. To be eligible for a bricklaying Apprenticeship, you will need to have some GCSEs in math, English and basic knowledge of mechanical drawing.====



===After read all this iformation.. I visited some webpages looking for images of structures mades on brick! Finally I choose this one..! ===



Brick sculpturing on   [|Thornbury Castle],    [|Thornbury] , near    [|Bristol] , [|England]. The   [|chimneys]     were erected in 1514. ==I choose this picture because I consider it beautiful and interesting. At the picture we see 3 chimneys totally made on brick and behind them there are a tower made on concrete. The bricks apparently were placed in a specific order with the intention of create a surface decoration in a geometric design. This design achieves an optical illusion that makes people believe that the chimneys are rotating. == ==The type of surface bricks is “Face Bricks” that’s why they are been used in the exposed face of the wall, that means that bricks have a higher quality, durability and a good appearance than common bricks. The most used colors of face brick are various shades of brown, red, gray, yellow, and white. At this structure, red bricks were used and we can see the different shades of the color, which creates a very pleasant chromatic effect. But I think that “Face Bricks” weren’t the only type of brick used at the construction of those chimneys, I guess that “Firebricks” were used inside of them. “Firebricks” are made of a special type of fire clay that will withstand the high temperatures of fireplaces without cracking or decomposing. It is larger than regular structural brick, and often, its hand molded. ==
