Claims: I claim:

1. A method of introducing a soluble chemical composition into an essentially non-aqueous fused chemical bath of which said composition constitutes a dissolved constituent, and wherein material to be treated is periodically introduced and removed from the bath, comprising the steps of,

dissolving said chemical composition in a volatile solvent having a boiling point less than the temperature of said bath,

providing spray nozzle means disposed to spray liquid droplets above said bath, and spraying said dissolved composition from said nozzle means above said bath in droplet size sufficiently small to allow said solvent to evaporate before said sprayed composition impinges on the surface of said bath, and agitating said bath, whereby the solvent will evaporate and the composition will enter the bath and become mixed therewith essentially free of volatile solvent.

2. The invention as defined in claim 1 wherein the solvent is water and the bath is maintained above 100.degree. C.

3. The invention as defined in claim 2 wherein the dissolved composition is maintained in a tank and pumped therefrom to said nozzle means.

4. The invention as defined in claim 1 further characterized by hood means disposed above said bath, and wherein said spray is directed within said hood means.

5. The invention as defined in claim 1 further characterized by controlling the rate of spray to maintain a given bath level.

6. The invention as defined in claim 1 further characterized by a plurality of nozzles, and means to supply different dissolved compositions to at least two different nozzles, and supplying different compositions from at least two different nozzles, whereby the components of a bath are separately added.
