BRICK MANUFACTURING. Brick Makers. In the late nineteenth century, most brick works were similar. Soak pits were used to prepare and mix clay. Clay was mixed with water and soaked overnight for softening so that it could be shaped into bricks using wooden forms. Once technology began to take over, molding the bricks into the proper shapes became easier by using a soft-mud brick machine. The machine automatically shaped the pieces of clay into the form of bricks. A talented brick maker could produce about 4,000 bricks per day by hand. By the 1890s, some brick machines could even produce up to 5,000 bricks per hour.

The next step was drying the bricks to make them hard and durable. Brick-makers would put the soft bricks into a steam-heated drying room. The drying room was usually the largest area of a brick works facility because they had to handle such a large amount of bricks at a time. Towards the end of the existence of the brick works, the companies used a drying tunnel which allowed the bricks to move through the drying room by a conveyor belt with steam heat blown on them. By using a drying tunnel a much higher quantity of bricks could be dried and finished at a time, achieving higher sales and saved labor. Before the technology of drying rooms and tunnels, brick-makers had to lay bricks outside to dry naturally in the sun.

The last process was to fire the clay in kilns to cook the clay before it went through a final drying process. By cooking the clay, all of the finer elements were fused with one another to create a stronger, more durable, solid mass.
