Making Multiples

Lost-wax casting allows foundries to make bronze sculptures from clay and plaster models.

Bronze Casting
Since antiquity, sculptors have used the lost-wax casting process to transform their clay and plaster models into bronze sculptures such as those on view across the gallery. This process captures the composition and the precise surface details of a model in a new material, and allows artists to create nearly identical versions of the same sculpture.

Tools and Techniques

The marks on a sculpture’s surface tell us about the process of its creation.

Use the images below to explore the surface of Gaston Lachaise’s Torso of Elevation, which stands behind you, and Lachaise’s tools, which are on the wall to your right. Slide the vertical bars back and forth to compare marks from the torso’s surface with the types of tools used to make them. Press the speaker button to hear conservator Tony Sigel explain how each type of tool was used in the making of this torso.
