Derwent Onyx Pencils are made from smooth dark graphite and give dense, rich, jet black tones, deeper than a graphic 9B. The core is non crumbly and can be sharpened to a fine point making it perfect for architectural drawing and technical design. Darker shades can be built up with increased layers.
Many pencil artists struggle to find that elusive 'blacker than black' line that doesn't have the shine of traditional graphite. There are a bewildering array of types of these pencils on the market with some using ink in the mix, some using charcoal, some using oil. Here we gather together a selection for you to try to see if you can find that perfect black line!
