The jar is then put in the air until quite hard, when the next coil is added in the same way. The third coil is brought in a little toward the centre, and subsequent coils come in still more, so as to make the form that of a jar cut exactly in half. After each coil is attached, it should be left in the air to stiffen, or the clay beneath will not support the coil in progress, so great is the strain in forming such a shape. Each time a coil is added the wall below should be criss-crossed with the steel tool (an extra precaution) and wet with slip. Care should be taken not to make the walls too thick, and to join the coils and finish the inside as it is made; for, when the jar is completed, it is impossible to get the hand and tool in far enough to smooth and finish it well.
When the jar is made, except for a diamond-shaped gap in the middle of the front wall, the piece to fill it is cut and fitted in. It will lie almost parallel with the back wall. Take care to make it full large for the opening, and join it to the inner edges most carefully, for here, if anywhere, is the jar liable to crack. The top is now made even by eye, using the pointed steel tool.
The pale-green rose-bowl with a moth design, at the left, has beside it a low Dutch dish. On the right is a fruit-bowl with a deep-green mat-glaze.
