the upper end of the feeder will be found suspended in the 
glassjthat covers the steel. 
The same or similar phenomena take place in separating 
crude iron from its ores, when highly carbonated, and difficult, 
from an excess of carbon, of being fused. 
The division of the wootz cake by the manufacturers of 
Hindostan, I apprehend is merely to facilitate its subsequent 
application to the purposes of the artist ; it may serve at the 
same time as a test of the quality of the steel. 
To ascertain, by direct experiment, whether wootz owed its 
hardness to an extra quantity of carbon, the following expe- 
riments were performed with various: portions of wootz of 
common cast steel, and of white crude iron, premising that 
in operations with iron and its ores, I have always found the 
comparative measure of carbon best ascertained by the quan- 
tity of lead which was reduced from flint glass.

Pounded flint glass three times the weight - 195 
This mixture was exposed to a heat of 160° Wedgewood, 
and the wootz fused into a well crystallized spherule of steel. 
A thin crust of revived lead was found below the wootz, which 
weighed 9 grains, or T ^ 9 3 the weight of the wootz.

The fusion of the mixture in this experiment was productive 
of a mass of lead weighing 1 o grains, equal to ^th the weight 
of the wootz.
