Abstract
An investment casting shell is made by providing an investment casting pattern that defines a cavity and filling the cavity with a fluid. The fluid is sealed within the cavity and a ceramic material is applied to the exterior of the pattern. The ceramic-encased pattern is heated and the pattern and fluid are removed from the ceramic.
