Question

What is the difference between using a sharp graphite pencil and using a blunt pencil in a tester, How does it differ?

Answer 1

Answer:

A pencil is an implement for writing or drawing, constructed of a narrow, solid pigment core in a protective casing that prevents the core from being broken and/or marking the user's hand.

HB graphite pencils

Coloured pencils (Caran d'Ache)

A typical modern-day pencil.

1. Solid pigment core (typically graphite, commonly called pencil lead).

2. Wood.

3. Painted body.

4. Ferrule.

5. Eraser.

Pencils create marks by physical abrasion, leaving a trail of solid core material that adheres to a sheet of paper or other surface. They are distinct from pens, which dispense liquid or gel ink onto the marked surface.
