BRICK MANUFACTURING. 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. (1)

In the early days, the drying process called "edging" required that the bricks be placed on their sides. Children earned ten cents an hour helping the turn the bricks. (2)

Longer drying periods of up to three weeks occurred in "alleys." When the bricks were dry enough, they were placed in kilns to be burned--a process from which they got their red color. "Mobile kilns" were taken to the construction sites for brick making with cooks accompanying the workers on out-of-town jobs. (3)

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.

Brick making in Dubuque was a casualty for many companies during the GREAT DEPRESSION.
