Method for melting a photographic composition gel to a sol.

摘要

Object: To provide a method for making a photographic composition gel ready for use in production from a good preservative frozen state, causing no change in photographic properties. Constitution: A photographic composition gel is melted to a sol by steps of carrying a shading dielectric preservative container holding lumps of a photographic composition gel in a dielectric heating apparatus which generates high frequencies capable of penetrating to a depth corresponding to the size of the above photographic composition gel lump, and melting the photographic composition gel to a sol by irradiating the above high frequencies from the outside of the container. <IMAGE>
