Special powders

Main uses: Latent fingerprints on non-porous and semi-porous surfaces.
 
The special powders mixtures are developed to improve the characteristics of concentrated or regular powders: 
- greasy features are reduced
- lumps are avoided
- prints show better contrast
- far fewer problems are encountered with excessive use of powder (e.g. smearing of prints)  
 
Consequently, the development of latent prints can be done much faster, with less risk and better results.
 

Swedish black

General use powder "most wanted"
Swedish Black fingerprint powder is an excellent powder for use with a squirrel hair brush. It combines a good adhesion to the fingerprint with minimal adhesion to the background surface.

Gold Special

Gold Special provides better contrast against light-colored surfaces than Silver Special. However, it adheres more strongly on surfaces and is therefore less suitable for routine use. Prints powdered with it and then lifted with a Gellifter will gradually sink into the gelatin layer.
