Ollas
In the moulding of ollas the first step is the building of the lower part of the body to a height of four or five rings in the same manner as in bowl-construction. Since ollas have a larger diameter than bowls, more than one roll is needed to form a complete ring about the growing edge. The number of rolls per ring varies from one and a half to four, depending upon the size of the olla and the part worked upon. When this first building has been completed ([pl. 15], a), the rim is smoothed somewhat and the scraping and shaping are at once begun.
The use of the kajepe in the shaping of ollas is identical in all details with that described above in discussing the moulding of bowls. The roll-junctions and the fingerprints are entirely removed and the sides of the vessel are flared a little. Great care is taken not to flare the sides too much, for the paste at this stage is still rather soft, and if the sides are flared unduly they collapse outward of their own weight. When the preliminary shaping has been finished the rim is smoothed a

little, and the olla is placed in the sun to stiffen. The moulding has now reached the second stage ([pl. 15], b).
The vessel remains in the sun from twenty to thirty minutes. This period may be extended to as much as an hour and a half, if the vessel is in the shade or if other things occupy the potter’s time. During all the drying periods, at intervals varying from five to fifteen minutes, the potter dips her right hand in the water of the lard-pail, and moistens the rim of the partly finished olla in order to keep it soft enough to permit perfect welding when additional rolls are added. While one vessel is drying, the potter is usually occupied with another. In case the work on the latter is finished before the former is dry enough, the potter simply waits, or finds some other work with which to occupy herself until it is ready.
