Ceramics techniques - AQASlab building and relief

Find out about the different ways to use and build clay and various finishing techniques that can be used to colour and decorate clay objects. These methods have advantages and disadvantages and require different skills, techniques and equipment.

Slab building needs careful preparation but can make some impressive sculptural objects or vessels.

A lump of clay is first rolled out onto either a sheet of fabric or paper, using a rolling pin. The clay needs to be flipped over and rotated to achieve an even slab.

Slabs are easier to work with once they have reached the stage. They can be cut using a potter’s knife or sharp modelling tool.

To attach slabs together, the two connecting edges need to be and . The slabs are pressed firmly together along the joining edges - the slip binds them.

Relief puts less stress on the clay so it is less likely to crack when fired. Slabs of clay can be laid over preformed objects to create 3D shapes. These can then be built upon using modelling and hand building techniques. This is useful for making masks.
