I found a website detailing some forgotten/abandoned photographic techniques.
Some excerpts:
CALOTYPE or TALBOTYPE. Paper sponged over with or floated on solutions of silver iodide and potassium iodide. When partially dry, the excess potassium iodide was removed by bathing in distilled water. Paper was sensitized in a solution of silver nitrate, acetic acid and gallic acid. After printing a feeble image was brought up to the required strength by an application of a solution similar to the silver nitrate sensitizer. Talbotypes produced rich warm brown images.
PINATYPE. A transparency was made on a soft emulsion of the lantern plate variety and developed in a tanning developer. The “printing plate” so obtained was bated for about two minutes in an engraving black or photographic brown pinatype dye. The dye was held in suspension by the gelatin in direct proportion to the extent to which it had been hardened by light action during printing. The plate so charged with dye was then washed free of the surplus dye and finally brought in contact with a sheet of paper coated with plain gelatin. The two were squeegeed together and left for several minutes, when the dye in the plate was transferred to the virgin gelatin. When separated, the gelatin bore the dye image. Any number of prints could be made by dyeing-up the printing plate and repeating the imbition process.
Apparently, this information was culled from this encyclopedia: The Focal Encyclopedia of Photography (2 Volumes) 1965 edition, 2nd reprint. Editorial Board: L.A. Mannheim, Daphne Buckmaster, Frederick Purves, P.C. Poynter, Norah Wilson, Paul Petzold, A. Kraszna-Krausz.
