1 66 Mr. Mushet’s Experiments on JVootz. 
upper surface it increased in size, and in the blueness of its 
colour, till it passed into the state of malleable iron. 
The break of this steel, though apparently soft, was the 
least homogeneous of the whole, and throughout it presented 
a very brilliant arrangement of crystal, which in other steel is 
always viewed with suspicion. 
General Remark. 
Uniformly the grain and density of the wootz are homoge- 
neous, and free from malleable iron towards the under or 
round surface ; but always the reverse towards the feeder or 
upper side.

Remarks in Forging. 
No. i . One-half of the cake was heated slowly by an anneal- 
ing heat to a deep red, and put under a sharp broad-mouthed 
chissel with a small degree of taper. It cut with difficulty, was 
reheated, and cracked a little towards one end of the slit or 
cut originally in the cake. 
The heat in this trial was so moderate, that I was afraid that 
the crack had arisen from a want of tenacity, occasioned by 
the heat being too low. 
The other half was heated a few shades higher, and sub- 
jected to the same mode of cutting ; before the chissel had 
half way reached the bottom, the piece parted in two in the 
direction of the depression made by the cutting instrument. 
The additional heat in this instance proved an injury, while 
the cracking of the steel in both cases, particularly the former, 
was a certain proof of the abundance, or rather of the excess 
of the steely principle.
