Thickness varies with the vessel size from over 1 cm. thick in the 

 larger vessels to as thin as 5 nam. in the smaller ones. Surface 

 smoothing is not as noticeable, except for some of the smaller vessels, 

 as in the polychrome varieties. 



Figure 64. — Escotd plain type vessel shapes from Co-2. a-c, Type 1 ; f-j, type 

 2; d-e, type 3; k-n, type 4. All based on Willey Co-2 drawings. 



Shapes. — Characteristic shapes include: 



Large globular jars with tall out-flared collars (fig. 64, a-c). Orifices 

 on these vessels run 20-25 cms., and diameters must be at least 40 

 cms. Average coUar height is 10 cms.
