Manufacturing Process |
| Smooth |
Die Skin Brick |
The smooth surface of this brick results from pressure exerted by the steel die as the clay is extruded through it.
|
| Semi-Smooth |
Wire-Cut (Velour Brick) |
This brick has a unique texture created by removing the die-skin surface with a steel wire or blade. Small particles and inclusions in the clay are dragged through a do pushed into the surface adding a slight texture oriented in the direction of the extrusion. |
| Paper-Cut Brick. |
In this case, a sheet of paper is placed on top of the brick prior to cutting the clay column into the brick. Wire cutters are then sliced down through the paper, dragging it a bit to make a brick with an irregular curved edge. |
| Medium |
Brushed Brick |
After leaving the extruder, the clay column passes under a wire brush. The texture on a brushed brick depends on the wire size and pressure of the brush on the column. Light pressure on a medium bristled brush produces a light brush finish. With added pressure, a rug texture is created. |
| Rolled Brick |
The clay column of extruded brick may be textured by the pressure of large wheels that have projections on their surface. These projections press into the brick surface. Short lines and depressions can be rolled onto the die-skin or velour surfaces. |
| Sand-Finished Brick |
Sand embedded into the brick surface adds texture to the brick. Sand finished brick may be made by applying sand to an extruded clay column. Initially sand was used to release brick from wooden mold boxes. |
| Hand-Molded Brick |
These bricks are individually formed and placed in a wooden mold to create a brick texture with folds in the surface and rounded edges and corners. No two are alike. |
| Rough |
Tumbled Brick |
This style of brick highlights irregular corner, edge and surface features.
|
| Roll-Back and Bark Brick |
After leaving the extruder, the smooth plane of the clay column is torn by mechanical means and broken pieces of the cur section are rolled back onto the surface. The surface of this brick looks like a tree with rough bark. |
