Quick Summary

The term "die skin" refers to the surface of clay that is formed as it is extruded through a die in the stiff-mud process of brick and tile manufacturing. This process involves forcing plastic clay through a die to create a continuous column, which is then cut into individual units. The "die skin" is the outermost layer of this extruded column.1

In modern brick production, this die skin is often removed and further treated to create various textures on the finished brick. For instance, wire cutting removes the die skin to create a semi-rough surface, while sand finishing involves applying sand to the clay column before firing. The texture of the final product is directly influenced by these manufacturing processes.1
