#291 In the foundry: "Moose Flats", con't . . .

The sprewed wax panel is now in the shell room at the foundry where it is dipped in a liquid ceramic shell slurry then covered in sand.  The first coat of slurry is thin which picks up every detail in the wax panel.  The dipping and sand process is repeated several times using thicker slurry and allowed to dry between each dip.

At right, a technician holds the wax panel by the sprews and dips into the slurry.

Below, the wax panel has been dipped in slurry and is then dusted with sand.
