ABSTRACT:
A process and an apparatus for melting solidified gel masses, in particular of photographic emulsions, which are introduced as solid pieces of any size or shape into a melting container having a perforated bottom and equipped with a tempering device, the gel mass when melted flowing through the openings in the bottom into a receiver underneath it, and being arranged and designed to prevent excessive exposure of the gel mass to heat. This is achieved by melting the layer of gel mass immediately above the bottom of the melting container with microwaves while the layers of gel mass situated above the aforesaid layer remain substantially uninfluenced by the radiation of microwaves.
