Regular Metallic Fingerprint Powders
Not to be confused with Magnetic Powders, Regular Metallic Powders have no magnetic properties so they're meant for use with regular brushes, and are most effective on plated or highly polished surfaces such as silver, nickle or chrome. After latents are developed, we recommend that excess powder be removed using a feather duster.
Using the correct powder is extremely important. Considerations for the powder are:
• The powder’s sensitivity to secretions
• The powder’s adherence qualities
• The powder’s reproduction capabilities
When using latent fingerprint powder:
• Never dip the brush directly into the powder jar. Measure out a small quantity on paper. Less is best.
• Carefully sweep the surface being examined with the brush or wand. A swinging motion or side-to-side motion will both work.
