Nitram Charcoal: A Distinct Third Category Between Vine and Compressed

Scott Maier, an artist and instructor at Rocky Mountain College of Art and Design, reviews Nitram charcoal, arguing it is not just another brand but a distinct medium bridging vine and compressed charcoal. Unlike vine/willow charcoal, which is fugitive and inconsistent due to wood knots, or compressed charcoal, which has a heavy feel from binders, Nitram is made from machined willow bâtons baked in a proprietary process that preserves the wood's cellular matrix, resulting in predictable, knot-free sticks that can be shaped to fine points. Nitram uses a color-coded hardness system: H (blue) for light grays, HB (red) for midtones, B (green) for dark values, and B+ (yellow) for extra-soft marks. The starter pack includes one stick of each hardness and a sanding block. Maier notes that Nitram erases well with kneaded and soft rubber erasers and works across various surfaces. He emphasizes that reframing one's understanding of charcoal types can expand artistic options.
