Unless, however, the aforementioned variables are understood and addressed, results can be frustrating and unpredictable. The amount of glue used depends upon the size of the chamber. Glue Masters. Superglue fuming is the process of heating superglue (liquid cyanoacrylate) and allowing the gases to stick to the oily residue that composes the hidden print. Plastic bags B. Iodine fuming I recommend doing several trial runs to get the hang of the process before attempting to develop any prints that you care about. It should be noted that latent prints under-fumed with the newer dye stain infused CA formulas will not fluoresce as intended. a.r))aN 7*(+Av~eUuMbmacA} AEuzVCH,6n4Iep=c2%J_tu`}x.WM+SPnz?d=vwhcGG!K('rCqd}vWm3BXo).
