A ceramic casting shell is formed by a method comprising the steps of coating a wax former with one or more layers of a ceramic slurry; drying the or each layer of ceramic slurry; wherein the dried layer or layers of ceramic slurry form a ceramic shell; applying over the ceramic shell, a coating of a polymer material; heating the formed assembly to melt and remove the wax former, wherein the polymer coating acts as a strengthening layer to the ceramic shell during the wax removal process; and subsequent to removal of the wax former, heating the ceramic shell to melt and remove the polymer coating. The polymer coating is preferably the outer coating of the ceramic shell. The polymer coating may be applied by spraying, dipping or painting onto the ceramic shell.

A low-pressure casting apparatus includes a core that together with a mold forms a cavity and a reduced-pressure dryer configured to dry the core under reduced pressure. The core is disposed in the mold, the molded is closed, the core is dried under reduced pressure, and thereafter the cavity is filled with molten metal.

An investment casting system includes a core having at least one fine detail, a shell positioned relative to said core, and a strengthening coating applied at least to the at least one fine detail.
