Using an armature when modeling a sculpture is essential because it provides support during the modeling process. An armature acts as a framework that stabilizes the structure and helps maintain its shape, especially when using materials that may be heavy, flexible, or prone to sagging. This support is crucial for the sculptor to work effectively, allowing them to build the form without the fear of collapse or deformation. The armature is particularly helpful in large sculptures or when working with soft materials like clay, where gravity can impede progress.

In contrast, while color can enhance a sculpture, that is not a primary function of an armature. Glazing pertains more to the finishing process of ceramic sculptures and is not directly associated with the armature's function. Additionally, rather than making a sculpture more fragile, an armature is intended to provide strength and durability, supporting the sculptural elements rather than compromising their integrity.
