Techniques of Throwing
There are many techniques in use for throwing ceramic containers, although this is a typical procedure:
A round, moist lump of clay body is thrown down onto the wheel head or a bat attached to it. The lump is made even and forced to the centre of the wheel by applying pressure with the hands. The thrower finds the center of the clay by moving a thumb across the lump until no more friction is felt. The thumb is pressed into the center of the lump, stopping about 5 mm from the wheel head. The hole thus made is widened. The sides thus defined are pulled up and made thinner by pressure between the hands. The vessel is shaped, and the mouth is smoothed. The vessel is cut from the wheel head with a cheese wire and left to stiffen. Sometimes the stiffened vessel is inverted on the wheel and trimmed with a sharp tool.
A skilled potter can quickly throw a vessel from 15 kg of clay. Alternatively, by throwing and adding coils of clay then throwing again, pots up to four feet high may be made, the heat of a blowlamp being used to firm each thrown section before adding the next coil. In Chinese manufacture, very large pots are made by two throwers working simultaneously.

“The techniques of opening conversation are universal. I knew long ago and rediscovered that the best way to attract attention, help, and conversation is to be lost. A man who seeing his mother starving to death on a path kicks her in the stomach to clear the way, will cheerfully devote several hours of his time giving wrong directions to a total stranger who claims to be lost.”
—John Steinbeck (1902–1968)

“Nothing more powerfully excites any affection than to conceal some part of its object, by throwing it into a kind of shade, which at the same time that it shows enough to prepossess us in favour of the object, leaves still some work for the imagination.”
—David Hume (1711–1776)
