When walnut wood undergoes high-temperature steaming, its light brown exterior gradually deepens, transforming into a rich, dark brown with black undertones. This is a natural metamorphosis, as if the wood, under the imprint of time, gradually settles into a profound essence. It's akin to how people, after the trials of life, shed their youthful naivety, revealing a steady and experienced demeanor. Every streak of deep brown and black is a mark of time, a testament to the wisdom and maturity gained by the wood.
North American walnut, also known as Black Walnut (scientific name: Juglans nigra), has sapwood that ranges from white to light brown, while its dried heartwood varies from light brown to dark brown, sometimes with purplish streaks or darker stripes. Over time, exposure to air gives the wood a rich chocolate color, with growth rings clearly visible. As a semi-ring-porous wood, its grain is usually straight but may occasionally exhibit wavy, curly, or figured patterns, including burls and crotches. The name "Black Walnut" originates from the transformation that occurs when walnut wood undergoes a specialized steaming process, turning its color from light brown to deep brown with black hues. This professional steaming and kiln-drying treatment enhances the wood's stability and increases its usability, even making the durable sapwood more valuable. As a result, North American walnut has consistently been one of the top wood exports worldwide.
