To remove from a casting mold or to separate a cast object from its mold after hardening.
From the prefix 'de-' (remove) combined with 'cast' (a molded object or the process of molding). This term appears in metalworking and manufacturing contexts.
The moment a metalsmith decasts a bronze sculpture can be the most anxious time—the object is fragile, still hot, and any mistake destroys hours of work, which is why ancient artisans developed elaborate rituals around this process.
