When sculptors work with soft materials what do they use to prevent sagging?

Sculptors working with soft materials, such as clay or wax, often use armatures to prevent sagging. An armature is a supportive framework, typically made of metal or wood, that helps maintain the shape and stability of the sculpture during the crafting process. Additionally, sculptors may occasionally use supports or props to bolster specific areas that are prone to sagging until the piece is fully set or hardened.
