Exploring 3D art materials with casting (paper and plaster)
I can explore casting techniques through hands-on experimentation to create casts using plaster and paper.
Lesson details
Key learning points
- Casting is a sculpting process that allow us to create replicas or translate modelled sculptures into durable materials.
- Hands-on experimentation with materials fosters a deeper understanding of their properties.
- Exploring different casting methods supports informed choices and more intentional outcomes in future projects.
Keywords
Casting - a sculpture making technique where a malleable material is formed in mould
Mould - a hollow container used to shape the malleable material
Undercut - a part of the mould that curves around the object or cast in a way that makes it hard to remove the object from the mould. It can trap the cast inside the mould if not designed carefully
Common misconception
Plaster and paper will behave the same way in a mould.
Plaster and paper have very different properties. Plaster sets quickly and picks up fine details. Paper air dries more slowly and shrinks more as it dries. It might not show fine texture as clearly.
Equipment
Tray or board, clay, plaster of paris, bowls, stirring sticks, petrolium jelly or cling flip, tissue paper, glue and water mix, objects to cast over, like small toys, keys etc.
