Calculated temperature difference between the liquid/solid interface and bulk of the melt was compared with the wide‐angle scattering (celluae density) of Al 2 O 3 and YAG crystals. Celluae free coloured crystals were grown using higher energy losses from the upper part of the crystal and the melt. Colourless crystals were successfully grown under opposite conditions. The results are in accordance with the calculated temperature differences which are proportional to the actual temperature gradient at the interface.
