An example of the use of fluorescent powders is the marking of banknotes in a petty cash box. We recommend mixing the powders below (e.g., in a ratio of 1:2:1) before application, retaining a small amount of the mixture for proof. Mixing makes the powder even more unique and thus better for identification. After applying the powder mixture to a banknote, rubbing it in with a cork will make the powder particles adhere better to the paper.

Fluorescent pastes are used for setting up thief traps with objects that do not lend themselves to the use of powder. After having been in contact with the paste, there is no visible coloration of the skin. Under longwave UV, however, the staining is clearly evident.

The marking crayons D-4000 to D-43000 are light-yellow wax crayons that fluoresce under longwave UV. These crayons have a diameter of 10 mm and a length of 10 cm. They are packaged 10 to a cardboard box.
The crayons fit in holder D-91000 but not in the crayon holder D-91100, which takes thinner colored marking crayons (diameter 8.5 mm).

Silver nitrate powder and silver nitrate paste are for setting up thief traps. On contact with the skin, the small silver nitrate crystals slowly react, and this creates typical black spots (silver stains) that cannot be washed away. Due to the reactivity of the powder, there is a certain health risk connected with its use (for example, if the powder on fingers is rubbed in the eyes).

The powder or paste are not suitable for all materials with which silver nitrate reacts (metal surfaces for instance).
