Mikrosil™ has been formulated to give excellent rendering of small details, highest contrast for
microscopic observations, good releasing ability for the cast and short setting-time. These properties
are important in cases of shallow marks and marks with small details requiring large
magnification.
Brown Mikrosil™ is a dark-brown color which many toolmark examiners prefer. The dark color
increases the visibility of detail in the casts made from toolmarks, firing pin marks, breech face
marks and other marks on cartridge casings. Gray Mikrosil™ is preferred by other toolmark
examiners who photograph the contrast between the light-colored surface and shadows produced
from side-lighting. As described below, squeeze an equal length from each tube onto the mixing
pad and stir them together with the wooden spatula. Press against the toolmark and wait for a few
minutes. The hardened cast will easily release itself from the surface.
White or Black Mikrosil™ can be used to lift dusted latent fingerprints from rough or textured
surfaces where regular lift tape will fail. Using the method shown on the following page, press the
mixed putty onto the latent print. Wait a minute or two to allow the putty to harden, then pull the
card with the putty attached away from the surface. Properly label the lifted latent print. Remember,
the image of the latent print is reversed, left to right. Use White Mikrosil™ with black powders
and use Black Mikrosil™ with silver or fluorescent powders.
