Description
Mikrosil Casting Paste Grey
Mikrosil captures fine surface detail and produces high-contrast casts for microscopic examination. It releases cleanly from the cast and sets quickly—especially useful for very shallow marks and small features that require high magnification.
Pack size: 200 g
Supplied with: Activator
Notes: Mikrosil Casting Paste Grey
Tool marks often provide crucial physical evidence at crime scenes and give forensic investigators valuable leads. Investigators typically focus on two main tool-mark types: impressions and striations. They can compare and match both types to help link a tool to a specific object or scene.
Impressions occur when a tool presses into a softer material such as wood, clay, or skin. These marks may form a three-dimensional pattern (for example, shoe or tire tread) or a two-dimensional impression (for example, a screwdriver mark on metal). Impressions can reveal the tool’s size, shape, and sometimes brand-related features. When investigators document these marks carefully, they can build a profile of the tool and support links to a suspect or object.
Striation marks form when a harder tool moves across a surface and scratches or scrapes it. Each tool can produce distinctive striations due to wear, manufacturing defects, or deliberate modification. Striations on materials such as metal, glass, or plastic can show how the tool cut or scraped the surface. Investigators can strengthen a case by matching striations on a suspect tool to striations recovered from the scene.
When investigators recover both impressions and striations, they gain a stronger set of evidence. Using microscopy and 3D scanning, they can compare the marks in detail, develop a profile of the tool, narrow suspect lists, and corroborate other information.
Conclusion: Tool-mark analysis supports forensic investigations by showing how specific tools interact with surfaces and by helping investigators connect a tool to a crime.
