Historical Background on Bricks and Brickmaking-III
 

Various brick making machines have been invented over the years. These either forced the clay into the moulds to form individual bricks, because the pressure applied was greater than could be obtained by hand, these bricks are usually denser than hand produced bricks and are more uniform in shape and density. Or, they extruded the clay through a die, this was then cut by wires into brick sized pieces. Small brick works began to develop at scattered sites throughout the country. This was mainly due to the rising demand for new buildings and a shortage of suitable building stone.  Initially bricks would be made on or close to the site where the building was to be erected. The whole process would be by hand and it could take up to nine months to produce the bricks for the job.

With the onset of the Industrial Revolution, the need for building materials to supply the new industries and housing for workers was paramount and, as technology developed permanent brick works began to be built. These were usually over the better beds of clay. These sites not only produced bricks but also roofing tiles, drainage tiles (important in a predominantly agricultural area) and other clay products. Brickworks grew up alongside the new industries. This suited all concerned, as the raw materials were bulky and difficult to both extract and transport to where they were needed. Inter-dependency was formed in the case of coal mines, the coal would supply the fuel for the brick kilns that were essential to all-year-round mass production of bricks, and the bricks provided pit shaft linings as well as the buildings for the colliery offices.  In the initial stages, a lot of these were manned by jobbing brick workers, who would come to the site; make as many bricks as were needed for the job in question, and then move on to the next job.
