What purpose do mother molds serve in the liquid latex molding process?

In the liquid latex molding process, mother molds serve the essential function of providing support for the latex mold. When a latex mold is created, it is flexible and can often be too weak to hold its shape on its own, especially during the casting of the final object. The mother mold is typically a more rigid structure that encases the latex mold, ensuring it maintains its form and can withstand the pressure and weight of the casting material without distortion.

This support is crucial in achieving accurate reproductions of the original object, as it prevents the latex from collapsing or deforming at critical points. In contrast, the other options do not align with the core function of mother molds: they do not cast metal parts, enhance color, or create texture; those aspects are related to other processes in mold-making or casting that do not involve the primary role of mother molds in maintaining structural integrity.
