Armature refers to a rigid framework, often metal or wood used to support a sculpture or other large work while it is being constructed. The armature provides support and shape for the work, and allows the artist to build up the form gradually.

An armature can be made from many different materials, including wood, metal, or even cardboard. It is important to choose a material that is strong enough to support the weight of the clay or other materials being used. The armature should also be easy to manipulate so that it can be moved and shaped as needed.

Once the armature is in place, the artist can begin to add clay or other materials to create the desired form. As the work progresses, the armature may need to be adjusted to provide additional support or to change the shape of the sculpture.

When the sculpture is complete, the armature can be removed. In some cases, the armature may be left in place to provide support for the finished work. However, in other cases, the armature may need to be dismantled and removed so that it does not damage the finished piece.
