1. A method for injecting a vaporizable material into a molten bath having a temperature which is significantly higher than the nucleation, combustion or decomposition temperature of the vaporizable material, comprising the steps of:

  • a) injecting a gas into the molten bath at a rate which is sufficient to cause the gas and the molten bath to form a gaseous dispersion, the gas component of the gaseous dispersion occupying a sufficient fraction of said dispersion to cause a significant portion of the vaporizable material, at a rate at which the vaporizable material is injected into the molten bath, to volatilize, combust or decompose during exposure to said gas component, and thereby ensure that the molten bath will not explode; and

    b) injecting the vaporizable material into the gaseous dispersion at a rate which causes a significant portion of the vaporizable material to volatilize, combust or decompose during exposure of said material to the gas component of said gaseous dispersion, thereby ensuring that the molten bath will not explode.
