It is a physical change, because you are only changing the shape of the clay and all of the chemical properties stay the same. Also, the molding of the clay is reversible. An example of physical change would be a melting popsicle because the substance is changing from a solid to a liquid and keeps all of it's properties. The substance doesn't change, only the shape/form.
Kneading is a method of preparing clay for use. When needing the raw clay the individual is removing air pockets that can cause cracking in the he clay when molding takes place.
