Step 1

Step 2

A broach can present two problems that make it difficult to mold.

1- Portions of a broach, like the edging of the broach pictured, can be too thin to make a deep enough cavity in the mold.

2- The pin on the back keeps the broach uneven and complicates the creation of an open back, once the mold has been made.
 

Roll out Safe-D-Clay™ slightly thicker than the depth the pin protrudes from the back of the broach. Press the broach, pin side down, into the Safe-D-Clay™ so the back of the broach is flush with the Safe-D-Clay™.

Step 3

Using the broach as a template cut through the Safe-D-Clay™ with an exacto knife or a shish kabob skewer so that the clay remains only underneath the broach. The broach is now ready to mold, since the edging has been thickened and the irregular back and protruding pin have been leveled by the Safe-D-Clay™.
