What is the characteristic of compressed charcoal compared to stick charcoal?

Compressed charcoal is characterized by its ability to produce deeper, richer blacks compared to stick charcoal. This is due to its denser composition, which allows for a more concentrated application of pigment. Artists often prefer compressed charcoal for creating strong contrasts and dynamic, expressive lines because it delivers a greater level of darkness that can significantly enhance the dramatic quality of a drawing.

In contrast, stick charcoal tends to produce lighter values and softer edges, making it less suitable for achieving the same depth of tone. While stick charcoal is easier to blend and can achieve a wider range of lighter values, it doesn't offer the same intensity of black that compressed charcoal can provide. Therefore, the richness of black that comes with compressed charcoal makes it a favored choice for artists aiming for bold, high-contrast artwork.
