CERAMIC STUDIO 
7 
In an oxidising fire, cone 013 marks the point at which 
tlie glaze is getting iiito a condition to be affected by car- 
burets, when all reduction must cease and the firing remain 
strictly oxidising to the end. Other cones show the progress 
of the firing. These cones, blunt and long in Germany, large 
and pointed at Sevres (Fig. 87), being silicates of alumina, 
resemble in their chemical composition the kaolinic products 
which the kiln contains. 
Whatever the advantages of these fusible tests, which one 
can see but not touch, they cannot be depended upon entirely 
to determine the exact moment when the firing should be 
stopped. It is necessary to use for this the trial pieces which 
can be examined after their extraction from the kiln. These 
pieces alone show the exact condition of the porcelain, its 
color, its translucency, the quality of the glaze and allow one 
to judge whether the firing should be stopped or continued for 
perhaps a nuarter of an hour, half an hour, sometimes an hour.

TILE-SECOND PRIZE-ROCKWOOD MOULTON 
ANCIENT MOHAWK POTTERY 
R. liorracks of Fonda, N. Y., while stalking deer during the 
last hunting season at the Little Falls of the upper waters of 
the Sacondago, near lake Piseco, caught in a heavy downpour 
of rain, was obliged to seek shelter from the storm under the 
ledges of the Little Falls. 
While sitting there his attention was attracted to what 
seemed to be a round, brown bowlder partly covered with moss. 
Carelessly striking it it gave forth a hollow sound. His curiosity 
being excited he dug away the earth with his hunting knife and 
soon laid bare a symmetrically formed earthen jar. 
The jar stands 10 inches high. At its largest circum- 
ference it measures 30 inches and at its smallest 20 inches. 
The circumference of the top or mouth of the jar measures 
24 inches. 
The vessel on the inside bears signs of use, but the outside 
shows no trace of fire, as is usual in Indian jars. The bottom 
IS rounded. 
The ornamentation around the top is of the usual style of 
the Mohawk pottery — that is, a series of straight and diagonal 
lines. 
The jar is a well-preserved specimen of Mohawk pottery, 
and is rare on account of the shape of the top, which is cut in 
three curves, forming three points, which gives it a triangular 
appearance. — Boston Morning Globe,
