The maximum fluidity (DDPM), G value and free swelling index (crucible number) indicate that the Shankodi-Jangwa coal sample is of medium-coking class.
The agglomerating and rheological properties of the coals revealed that only Shankodi-Jangwa coal has some coking properties with a crucible number of 3.0, temperature range of 107°C, maximum fluidity of 300 and dilatometric G value of 0.96, indicating that it is a low-plasticity and medium-coking coal, which may be blended with strongly coking, low-ash, low-sulphur and high-fluidity coal.
The rheological characteristic values like the softening temperature, resolidification temperature and maximum fluidity of Garin Maiganga and Tai coal samples were not detected; therefore, zero values were observed.
They did not fracture during compression, had high values for cohesiveness and chewiness, melted at lower temperatures (56 62°C), attained maximum fluidity at a lower temperature (72 78°C), and congealed at 54 to 69°C.
As ever, Coleman was seeking maximum fluidity between his players, the blues wail from his saxophone was as moving as ever, and the album received a Pulitzer prize.

The maximum LT during heating was as an index of the maximum fluidity of the molten cheese.
In 2002, Diez et al. reported that a Gieseler plastometric maximum fluidity between 200 and 1,000 DDPM is desirable for a good coking coal blend[16].
The Shankodi-Jangwa coal sample was observed to soften at a temperature of 388°C, attained a maximum fluidity of 300 DDPM at a temperature of 455°C and finally resolidified at a temperature of 495°C.
