Main uses: Latent fingerprints on non-porous and semi-porous surfaces.
 
Blower brush powders are special developed for use with the Blower brush.

Concentrated blower black is a unmixed fine milled powder and excellent for use with a blower brush. It has a good adhesion to the fingerprint with minimal adhesion to the background surface.
 

Special blower silver is a mixture of an aluminium milled flake powder and an inert material. Very suitable for relatively clean and smooth non-porous surfaces such as glass, painted wood, steel furniture, hard plastic. Excellent contrast against dark surfaces and black gelatin lifters. This powder is suitable for most surfaces found at crime scenes that have to be processed for fingerprints.
