Carbón vegetal Pitt, 3-6 mm

Las barras de carbón natural son el más antiguo material del mundo para dibujar y realizar bocetos. La sombra gris-azulada se desliza suavemente por el papel, se emborrona y difumina con facilidad, se borra sin dificultad y admite superposiciones. Su tono azulado siempre ha causado admiración, incluso entre los maestros de la vieja escuela. Los lápices carbón permiten trazar líneas mucho más negras. El carbón mezclado con hollín y arcilla otorga a los lápices carbón su color negro intenso pudiendo fabricarse en distintas graduaciones.
