  • Process for making pictorial reproductions
    Patent number: 6511795
    Abstract: A process of transferring a photographic image to a stone surface, such as slate tile, provides for the use of a gelatin subbing solution in a step of preparing the stone surface for the receipt of the image. Additional steps include application of polyacrylic coating and concrete staining material to the surface prior to exposing the surface to the gelatin subbing solution, and using conventional photo developing compounds for permanently affixing a transferred image to the stone surface. Mixing gelatin, chrome alum and water makes the gelatin subbing solution. For an “antique” look, the photograph can be exposed to a sulfide sepia toner prior to transfer of the image to the stone surface.
