Natural charcoal sticks are the oldest sketching and drawing material in the world. The greyish-blue shade glides softly across the paper, rubs and smudges easily, and can be erased without difficulty and repeatedly overlaid. Their blueish hue has always held a fascination, even with the old masters. The charcoal pencils leave a much blacker line. Compressed charcoal with soot and clay give the charcoal pencils their deep black colour and can be produced in different degree of hardness.
- The Pitt Charcoal set contains 2 charcoal pencils (degree of hardness: soft, medium), 4 natural drawing charcoal sticks (√ò 3-6 mm), 3 pressed charcoal sticks (extra soft, soft, medium) and 1 kneadable eraser
