Abstract: A method of melting sulphur, in block form, uses a heating device having lower heating surfaces and means for withdrawing sulphur. The device is positioned on a block of sulphur so that the heating surface(s) are inclined downardly to a collection location spaced inwardly from sides of the sulphur block. The heat is supplied to the heating surfaces to melt sulphur, and molten sulphur is withdrawn by the means for withdrawing it. As sulphur is melted, the heating device is progressively lowered through the block of sulphur. A corresponding apparatus having inclined heating surfaces is provided. As the sulphur is melted so that molten sulphur runs down towards the collection location, the device can be used right up against the edge of a block of sulphur.
