By the method of physical modelling the influence of the crystal rotation rate and crystallization front sag on occluded gas distribution in melt at lead molybdate growth has been investigated by the Czochralski method. Glycerol water solution was used in the model instead of lead molybdate melt. Polystyrene particles of l.06 $g/cm^3$ density were used in glycerol solution instead of gas holes. Some reasons, causing, occluded gas distribution in the observed model have been discussed.
