Ficure 93.—Manakakashin Red-on-White, Taruma Phase. a-f, Motif 3: broad lines. 
DECORATION (figs. 92,93; pl. 45). 
Technique: Thick, dark-red paint applied to white-slipped surfaces in lines. 
On some sherds, all or parts of the painted lines are black; however, close 
examination of the underlying pigment indicates that this discoloration 
is an accidental alteration of the normally red paint, either as a result 
of firing or of chemical action in the ground. Width of the lines varies 
from 0.5-10.0 mm., with the extremes not normally present on the same 
sherd. Hxecution is typically careful, without overshot junctions of the 
lines. Parallel lines approach true parallelism and inequalities in spacing 
are not pronounced. Although broader-lined designs have suffered more 
from erosion, it appears that they were originally less carefully executed 
than the fine-line designs. 
Motif: Red-on-white designs are normally placed on the exterior, although 
a few sherds have this decoration on the interior surface in addition 
to or instead of on the exterior. In the remainder the interior is plain 
or covered with a red wash. Three major types of motif occur with 
approximately equal frequency: 
1. Intricate, delicate, all-over patterns of small, concentric diamonds, 
triangles and intervening parallel lines (fig. 92, a—c; pl. 45, a, c, d). 
In one case squares and triangles are filled with parallel lines. The
