Steps 1-2

Steps:

1. Carve a wax blank into the desired clover shape with carving tools, files and a craft knife.

Step 3

3. Place a metal casting flask over the base and seal the base to the flask with clay.

Step 4

4. Mix the powder investment with water and pour it into the casting flask surrounding the wax ring. Remove the bubbles from the investment mixture by placing the flask on a vibrating pad.
