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. View our Technical Note for more information on how to use Iodine.
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.
