Iodine fuming is a method of
developing latent prints on paper, cardboard, and many other paper surfaces.
Iodine fuming should be used before Ninhydrin or Physical Developer (or
other silver nitrate-type solution). Because it reacts to a different
residue, it will not interfere with their subsequent application. This kit
comes complete with carrying case, Iodine fuming apparatus, Drierite®
crystals, glass wool, and Iodine crystals. Replacement items are available.
Shelf-life of Iodine crystals: by
keeping the jar tightly sealed, the Iodine will last for months. Once the
jar is opened, the material will begin to sublimate (change from a solid
into a gas without going through a liquid stage) immediately, so work
quickly. This product is very corrosive and will rust many types of metals.
Do not store it in a drawer with metal handles or fixtures. |
