Which outcome arises during ancient lost-wax casting if excessive moisture remains trapped inside the ceramic shell mold?

💡 Explanation

A steam explosion occurs due to rapid phase transition; residual moisture vaporizes violently within the mold upon molten metal introduction, creating excessive internal pressure. This rapid expansion causes a steam explosion, therefore metal is expelled from cavity, rather than increased fluidity or prevention of surface oxidation.
