Figure 29
Now attention is given to the front of the wall. A clay modeling tool is used to smooth out its surface.
Figure 30
A second key is created in the clay wall at the top of the head.
Figure 31
A third key is created opposite the first key. See the arrow.
Figure 32
Two more keys will be created and added by cutting three trapezoid shapes in clay.
Figure 33
One trapezoid key is applied on each side of front of the wall about halfway between the lower indented key and the top indented key.
Figure 34
Plaster is mixed for the front half of the plaster mold. The consistency of the plaster is similar to a thick milkshake.
Figure 35
The “face” coat (the coat that first touches the surface) is applied using a chip brush. This method eliminates air bubbles as a surface air is pushed aside by the brushing action.
