Daguerreotype Sensitising Sliding Box (For 8 ½ x 15 inch Plate and smaller)
I was given a glass container to work a month ago to build a sensitising box around it. As seen in the image below, it was impregnated with the iodine fume and it gave quite a smell into my workspace. However, I had left it by the window to air it and sun it, and it eventually evaporated and left very light amber tint and there was not smell emitted since. And the epoxy are unaffected and didn’t give out and the container is still intact as the first day received.
Initially I thought of simple sliding box much like the french sensitising box which I had built together with Brenton West before (refer to CDags’ website here under technology section), though the large plate requires a good amount of enclosure and I believe the usage of screw to push the plate firmly for good seal is needed. Refer to Takashi Arai’s, Eugene Galasso’s, and Ty Guillory’s sensiting box on the same page from the link before.
Since the plate is quite wide in landscape format, two screws would be needed for equal pressure.
As the screws width are ¾ thick, two would be needed, and it was added with elevated pyramid “X” underneath each of the screw contact to spread the pressure when clamped down.
Notice on the iodine embedded into the epoxy had dispersed when it was sunned and aired out, and the marine grade epoxy had held strongly and without any degradation.
The plate inserts were made with acrylic laser cuts.There’s also strip of 35mm and medium format reducers to fit into the 8 ½ x 15 insert.
Refer to the video below as well to see the fitting of this box, of course, this is not a speedy contraption as the size of the plate is large.
