Some of these properties appear to be evident in this iceberg, though the channel may have since been widened and enlarged by the subsequent tidal and surface melting and erosion.

When the reaction products form as high melting point CA2, CA6 and MA spinel in a continuous solid phase it will clog the liquid channel and resist the further diffusion of fused slag in the brick.

Moreover, there were exothermic peaks on the DSC melting curves of the skin layer and water channel layer at both positions, which indicated the phenomenon of recrystallization.
