[[File:Bricks traditional factory.jpg|thumb|Bricks traditional factory in Tehran]] A '''brick factory''' or '''brickworks''' is a factory for making [[brick]]s from [[mud]] by humans. There is no modern equipment in traditional style brickmaking. ==History== The oldest discovered bricks were originally made from shaped mud and dating to before 7500&nbsp;B.C. They were found at [[Tell Aswad]], and then later in the upper [[Tigris]] region and in southeast [[Anatolia]] close to [[Diyarbakir]].<ref>[http://wikis.ifporient.org/archeologie/index.php/Tell_Aswad IFP Orient - Tell Aswad]</ref> Other more recent findings, dated between 7,000 and 6,395&nbsp;B.C., come from [[Jericho]] and [[Catal Hüyük]]. In the ancient [[Indus Valley]] city of [[Mehrgarh]], mud bricks have been found dating to 7000 BCE. (Kenoyer 2005) Ceramic bricks were used as early as 4500 BCE in early [[Indus Valley]] cities. ==Equipment== Most brickworks have some or all of the following: * A [[kiln]], for firing, or 'burning' the bricks. * Drying [[Yard (land)|yard]] or [[shed]], for drying bricks before firing. * A yard land for manufacturing the bricks. * A [[quarry]] for clay. * A pugmill or clay preparation plant ==Brick making== [[File:Brick production in Songea, Tanzania.jpg|thumb|Bricks set out to dry in [[Songea]], [[Tanzania]]]] In a traditional brickworks, clay is taken from the quarry, and then carried by workers to the yard After the forming or cutting, the bricks must be dried, in the open air, in drying sheds, When the bricks have been dried, they must then be fired or 'burnt' in a kiln, to give them their final hardness and appearance.
