Pencil Graphite Debris Through the Microscope

Pencil Debris

This is from an environmental tapelift collected in an office.

Transmitted Off Circular Polarized Light and Reflected Darkfield Illumination


Pencil debris includes the carbon fragments from the "lead" of the pencil, wood sawdust, and paint from the surface of the pencil. The carbon fragments are actually a blend of clay and graphite.

Significance in the Environment:

Characteristic Features:

Graphite is relatively reflective and so the particles from the pencil lead are speckled when viewed with reflected light.

Associated Particles:
