Nitram produces its charcoal using a unique process that maintains the wood's cell structure which increases the charcoal's durability and helps prevent breakage. Nitram charcoal doesn't break like willow or vine do, and feels much less brittle.
Because of its solid strength, the charcoal can be sharpened to a fine point with the Nitram Sharpening Bloc. Also you produce less dust when working expressively. The charcoal allows for deep dark shades while still being easily erased for luminous light effects.
The Bloc de Saule is a large square edged extra soft stick, great for sharp marks as well as covering large areas. If you are working on a piece that requires extra deep black then the Bloc de Saule is more black than the Nitram B.
Box contains 1 charcoal stick.
The charcoal is approximately 152 mm long, 46 mm wide, and 15 mm length.
