KIDDER-GUPRNSBY] ARCHEOLOGICAL EXPLORATIONS IN ARIZONA 135 
The vessels of the groups above mentioned are made of a clay that 
was originally dull gray; normal firing has turned their surfaces 
to a warm, yellowish flesh color, hard to describe, but when once seen 
recognizable at a glance. In cross section there is a central streak 
of the unchanged gray clay, broader or narrower according to the 
thoroughness of the 
firing. Pieces of the 
plain yellow ware 
(class 4) were made 
of this clay and fired 
without modifica- 
tion; the other three 
classes were pro- 
duced by the appli- 
cation of varying 
slips and pigments; 
these differences 
have been used for 
classification, but 
there are further 
differences in the 
shape of the vessels 
and in their decora- 
tion that will be dis- 
cussed under the 
class heads. 
REDWARE WITH 
SHINING PAINT: This 
bears an even coat of 
fine red slip cover- 
ing the visible sur- 
faces of the vessels 
(the interiors of 
small-mouthed pieces are unslipped) ; this was worked down, prob- 
ably with the rubbing stone, to a very smooth, uniform finish 
which is not exactly polished, yet has a pleasant “slick” feeling to 
the touch. The most striking feature of the ware, however, is the 
pigment used in its decoration, a bluish or slaty paint with a distinct 
sheen or gloss. It is in no sense a glaze, its glossy appearance being 
due to its susceptibility to mechanical polish. Analyses have not 
been made, but we suspect that graphite will be found to play some 
part in its preparation. 
Vessels of this ware so far observed are: Bowls, small-mouthed 
pieces with pitcherlike handles, and seed jars. The bowls are char-
