Abstract
The present invention is a cone insert for a liquefaction kettle. Pads on the bottom of the cone separate the cone from the surface of the kettle. Solid material is added to the top of the cone. Solid material is melted on demand by an internal spray kettle ring. The cone insert provides continuous liquefaction and prevents sensitometric shift in photographic emulsions.
