Brief Description: | Experimental photogenic drawing (cyanotype) by Sir John Herschel, originally undated but 1842, dates of subsequent inspections and treatments given as October 21, 1842 and July 3, 1843. An unusual cyanotype experiment, with a long annotation recording Herschel's inspections over a long period, and several fadings and re-exposures. In summary, the image faded (disappeared to blue) when put by in the dark; Herschel exposed it to the engraving again but it faded again; on October 21 he exposed it again and noticed the revival of the earlier image; by July 3 it had disappeared again when put by in the dark; he exposed it again but this time it was not successful. Subject: engraving, no visble image Technique: contact copy Format: not apparent, inscription horizontal Polarity: not apparent Orientation: not apparent Quality: no image, slight hint of lighter border Colour: strong dark blue all over, pale blue back Chemistry: cyanotype, no washing or fixing is recorded Coating: none Inscription: number, long inspection and procedural note, with dates Paper: normal Condition: good Purpose: an experimental cyanotype, incorporating experiments on the fading, re-exposure, and revival of the image.
