About 4½ pounds of well-mixed clay,
A plaster slab about 10 by 12 inches,
The oval tools of sheet steel,
The pointed steel tool,
A rolling-pin,
Ultramarine blue water-colour paint,
A medium-sized paint-brush with fine point,
A saucerful of ground, baked clay, mixed with water.
An Indian water-jar of basketry, smeared with pinon gum, pointed at the bottom so that it could be set upright in the ground or hung by leather thongs to a tree, suggested the form of this jar. One side is made flat, so that it can hang against the wall of library or piazza holding some long trailing plant that grows in water, ivy, or wandering Jew, or wild flowers gathered on a walk through woods and lanes. What more appropriate way to make it than the Indian process described in Chapter II.? We shall need about four and a half pounds of clay, well mixed. A large lump, almost two pounds, is flattened out on a table, with the thick part of the hand and then made even with the rolling-pin. The sheet of clay should be ten by twelve inches, and not less than three-eighths of an inch thick. Upon it the jar form shown in Fig. 29 is outlined with a pencil, making it as large as possible to allow for shrinkage. It is then cut out with the pointed steel tool and transferred very carefully to a large plaster slab, where it remains while the walls are being built upon it. A coil of clay is rolled out, as described in Chapter II., and beginning at the left side of the jar shape, at the top, it is attached to the edge (which has previously been criss-crossed with a steel tool and wet with slip), all the way around to the opposite side of the top.
