Ziegelformen

Ziegelformen are molds used in the production of bricks. Traditionally, these were made from wood, particularly pine or fir, due to its availability and workability. The wood would be shaped into a rectangular box, often with slightly sloped sides to facilitate the removal of the brick. Early forms were hand-held and operated by a skilled brickmaker.

The process involved filling the mold with wet clay, which was then compacted, typically by hand or with a tamper. Excess clay was scraped off the top to ensure a flat surface. The filled mold was then inverted, and the shaped clay brick was carefully placed on a drying area. Wooden forms required regular maintenance, as the clay could cause them to swell and warp.

Over time, the design of ziegelformen evolved. Metal forms, particularly cast iron, were introduced, offering greater durability and precision. These were often heavier and more robust, suitable for industrial brickmaking. The development of automated brick presses also led to the design of more complex and specialized molds. Despite technological advancements, the fundamental principle of using a mold to shape clay for firing remains central to brick production. The term "Ziegelform" is German for "brick mold."
