Ceramic Shell

Ceramic shell is a series of refractory coatings on the wax patterns, alternating between slurry and stucco, basically glue and sand.

Completed waxes on sprues are dipped in slurry and stuccoed, and dried between each coat. Usually, 6-12 layers are built up. When the ceramic shell is sufficiently thick (1/4"-1/2"), the wax pattern is burned out, leaving an empty vessel ready to be filled with metal.
