The coal-tar or asphaltum and clay we beat to a temperature of at least 212 Fahrenheit hel'ore .mixing'them with the, pulverized coke. After the ingredients have'bee'n thoroughly mixed we form the mixture intoycakes of sufficient size to make, when pressed, blocks weighing from oneto four pounds, ,inore or less, and these cakes we subject to a pressure offrom one to three thousaml tons, so asto'f provide blocks of great solidity.
