Overview of the Sirchie Volcano Latent Print Powder | 101L
When you dust a scene and the print refuses to show, the problem is usually the powder. Sirchie's Silk Black Volcano Latent Print Powder (101L) has been the standard against which other oxide powders are measured for more than sixty years, and the reason is simple: it works.
Silk Black is a micro-milled oxide powder that clings faithfully to the minute ridge detail left by latent fingerprints, delivering crisp, high-contrast results on light-colored, non-porous surfaces. Forensic investigators, crime scene technicians, and law enforcement professionals keep coming back to 101L because the formulation has never needed a redesign.
Key advantages at a glance:
- Micro-milled particle size for maximum ridge definition
- Superior contrast on light-colored surfaces
- Proven on painted wood, metal, and most plastics
- Trusted formulation unchanged for over 60 years
- Packaged in a resealable 2 oz. (59 ml) dark glass jar
Whether you work a busy property crimes unit or process evidence in a forensic lab, 101L gives you a reliable starting point every time you open your kit.

Compatibility
Sirchie Silk Black Volcano Latent Print Powder 101L is designed for non-porous, light-colored surfaces. It performs reliably on:
-
Painted wood surfaces (doors, furniture, trim)
-
Metal surfaces (appliances, firearms, vehicles, hardware)
-
Most plastics (packaging, electronics housings, hard containers)
For best results, apply to clean, dry surfaces free of moisture or oil contamination beyond the latent deposit itself. Silk Black's dark pigment provides maximum contrast against white, cream, beige, and other pale backgrounds.
Not recommended for:
- Dark-colored surfaces, where Silk Black's contrast advantage is reversed (consider white or gray powder instead)
- Porous surfaces such as raw wood, cardboard, or fabric (chemical developers are more effective on porous substrates)
- Wet or heavily contaminated surfaces
This powder is not compatible with magnetic applicators; a standard latent print brush is required.
Intended Users
Sirchie Silk Black Powder 101L is built for professionals who need accurate, reproducible results in the field or in the lab.
Forensic investigators and crime scene technicians rely on 101L as an everyday go-to for latent print development on the most common non-porous evidence surfaces encountered at residential and commercial scenes.
Law enforcement officers who conduct their own field processing benefit from the powder's simplicity: open the jar, load the brush, dust, and lift. No mixing, no chemical handling.
Forensic laboratory professionals appreciate the consistent particle size and stable long-term formulation, which makes comparative work between submissions more predictable.
Security and investigations professionals in private practice, insurance investigation, or government work also find 101L useful whenever rapid latent print development is needed without laboratory infrastructure.
Students and instructors in forensic science programs use Silk Black as a training standard because its behavior closely mirrors professional expectations in real casework.
