38 WASHING, COKING, AND CUPOLA TESTS. 
Illinois No. 24 A. — Test 119: No coke produced; ashed down about 4 inches. 
Test 155: No coke produced; all volatile driven off; high heat of by-product ovens 
quickly applied might produce coke. 
Illinois No. 24 B. — Test 145: Dull-gray color; practically no cell structure; barely 
stuck together; very poor, dense coke, with high sulphur. 
Illinois No. 25 A. — Test 120: No coke produced. 
Test 140: Dull-gray color; cell structure small; soft, dense coke; breakage poor; 
two distinct layers of 16 inches and 8 inches, the lower coming out in chunks; 
high ash and sulphur. 
Illinois No. 26. — Test 143: Dull-gray color, soft, dense coke; breakage poor; practi- 
cally no cell structure; ash and sulphur high. 
Illinois No. 27. — Test 144: Poor, soft, dense coke; breakage poor; sulphur high. 
Illinois No. 28 C. — Test 166: Dark-gray color; cell structure small; breakage, good, 
uniform size. 
Illinois No. 29 A. — Test 169: Dark-gray color; drawn from oven in three distinct 
layers; breakage poor; large chunks and small-fingered pieces; poor, dense 
coke; high sulphur. 
Test 170: Dull-gray color; some silvery coloration; metallic ring; drawn from 
oven in 6-inch chunks of practically uniform size; cell structure good; more 
rapid burning and higher heat produced gave much better coke than former 
charge; sulphur high. 
Illinois No. 34 B. — Test 190: Light-gray and silvery color; metallic ring; cell structure 
a little large; breakage good; uniform-sized pieces; yield low on account of 
burning, but could be easily increased on better acquaintance; good coke; 
sulphur high. 
Indiana No. 3. — Test 14: No coke produced; ashed down about 10 inches and blaze 
lost. 
Indiana No. 4- — Test 6: Light-gray color; cell structure a little large; breakage some- 
what marred by cross fracture. 
Test 9: Light-gray and silvery color; metallic ring; fine-fingered pieces; cell 
structure large; ash and sulphur reduced by washing. 
Indiana No. 5. — Test 8: Light-gray and silvery color; metallic ring; cell structure 
large; breakage, good, long pieces; good coke. 
Indiana No. 6. — Test 12: Light-gray and silvery color; cell structure good; breakage 
good; metallic ring; good coke, but ash and sulphur high. 
Indiana No. 7 A. — Test 13: Light-gray and silvery color; metallic ring; cell structure 
large; breakage somewhat marred by cross fracture, somewhat brittle; ash and 
sulphur high. 
Indiana No. 9 A. — Test 16: Light-gray and silvery color; cell structure small; breakage 
somewhat marred by cross fracture, brittle; ash and sulphur high. 
Indiana No. 9 B. — Test 17: Light-gray and silvery color; cell structures mall ; long- 
fingered, heavy coke; high ash and sulphur. 
Test 18: Light-gray and silvery color; metallic ring; breakage somewhat brittle; 
cell structure good; ash and sulphur somewhat reduced by washing, but still 
high. 
Indiana No. 11 D. — Test 51: Light-gray color; metallic ring, breakage, long, fine- 
fingered pieces; cell structure medium. 
Indiana No. 12. — Test 108: Light gray, with a little silvery coloration; metallic ring; 
cell structure a little large; breakage, good-sized pieces; ash and sulphur high. 
Test 109: Light-gray color; some silvery deposit of carbon; cell structure large; 
breakage, good-sized pieces; ash and sulphur reduced by washing, but still high. 
Test 110: Light-gray color; some silvery deposit of carbon; breakage practically 
the same as in test 109; somewhat larger size; cell structure not quite so large; 
metallic ring; good weight; ash and sulphur high.
