In performing the method a pencil made of powdered coal formed under pressure is inserted into a precisely calibrated narrow tube and topped by a calibrated steel rod which slides in the bore of the tube. The whole is heated at a constant and definite rate. By making regular readings of the displacement of the rod as a function of the temperature and expressing the displacements observe
