Answer 1

Throwing a clay pot, the age old art of making pottery on a wheel, is a process that requires many steps.

Assuming the potter does not have to make his own clay, the first step toward the finished product is wedging the clay. Here, the potter kneads the clay to prepare it for throwing. Wedging cannot be rushed. A minimum of fifty turns is required to rid the clay of air pockets and align its molecules. Once wedged and formed into a ball, the clay is thrown onto the center of a potter's wheel. Now the material must be centered. Centering not only takes strength but time as well. The clay must be coerced into a perfectly symmetrical shape, dead center on the spinning wheel. To proceed with poorly centered clay is to court certain disaster in the form of tilting, uneven pots, or worse, the total collapse of the piece. When correctly centered, the clay is ready to be opened. To do this, the potter finds the center of the clay and slowly sinks a rigid finger into the still-spinning clay. Only now can the clay be shaped. With a steady but gentle hand, the potter pulls up the sides of the pot until the desired height is reached. Now the shaping is completed and the pot is ready to be dried, fired, and glazed. Thus, even though a clay pot may appear simple to make, fashioning one by hand is a long and sometimes tedious process
