CENTERING - Clay on a wheel for pottery throwing.
ca: CENTRANT – Argila sobre el torn per tornejar.
es: CENTRANDO - Arcilla sobre el torno per tornear.
Centering clay: The clay has been placed on the wheel and as the wheel rotates, pressure from the palm of your hands raises it into a column. It is then forced down with the right hand and the left controls it and keeps it from spreading. These movements are repeated to create the basic shape. When centered correctly the clay can be formed into circular objects.
