Figure 44.—Rim and base profiles and reconstructed vessel shapes of Koberimo Plain, 
Mabaruma Phase (Appendix, table 12). 
ForM : 
Rim: Thickened by the addition of a coil to the exterior, producing a broad 
fiat top with a rounded lip; unthickened and sharply everted producing a 
broad flange with either a rounded or tapered lip. 
Body wall thickness: 4-9 mm.; majority 6-7 mm. 
Body diameters: 20-36 cm. 
Base: Fiat, flat pedestal or annular (see Mabaruma Plain for description).
