Crossword-Solution: COKING 6 letters, 1 clue 🏆 scrabble score: 13

The region of Connellsville contains almost 150 square miles underlaid with coal that has a particular heat value when submitted to the process known as coking.

Frick's entrance into the combination gave the concern an unlimited supply of the highest grade of coking coal.

His son took over after his death and improved the methods of coking, strengthened the bellows, and added ore limestone and other reagents to the mixture.

After the coking process has progressed sufficiently, the edges should be packed down and the fire made as small as possible while still surrounding the ends to be joined.

But an economy which promises to be of great importance is now sought in the recovery and useful application of those constituents of coal which, in the coking process, have hitherto been lost; or, as an alternative, in a similar recovery in those cases in which the coal is charged in a raw state into the blast furnace, as is the practice in Scotland and elsewhere.
