In a process for solidifying molten sulphur by pelletizing, pastillating or slating, the hardness of the end product is improved by heating the molten sulphur to a temperature greater than 160°C, preferably 180-200°C before, commencing the solidification process. The main solidification process described is pelletizing, and this is preferably performed by cooling the previously heated sulphur to 145-155°C before introducing it as a molten stream into an aqueous coolant and incorporating a silicon compound as an additive in the molten sulphur to further improve product hardness.
