Plastic ceramic raw materials involve any clay material
Plastic ceramic raw materials involve any clay material that when mixed with water reveals the property called plasticity. Plasticity may be defined as a property which allows the deformation of the clay when an external force is removed. The large group of nonplastic ceramic raw materials include minerals, rocks and artificial chemicals that when mixed with water is not plastic.
