What is the purpose of using an armature in sculpting?

The purpose of using an armature in sculpting is to provide structural support. An armature is essentially a framework or skeleton that supports the weight of the material being used, whether it is clay, wax, or another medium. This support is crucial, especially in larger or more complex sculptures, as it helps maintain the shape and integrity of the piece during the sculpting process and before it is hardened or finished. By ensuring that the sculpture holds its form and does not collapse under its own weight, the armature allows the artist to focus on the details and overall composition without worrying about the stability of the structure.

In contrast, other options such as using an armature for aesthetic purposes, aiding in glazing, or creating texture are not primary functions of an armature. While an armature might indirectly influence the aesthetic outcome by enabling more elaborate designs, its main function is to ensure that the sculpture remains stable and structurally sound throughout the creation process.
