National Walnut: Characteristics and Applications
Lightweight and strong
The name walnut is applied to a number of brown figured woods, but only those produced by the Juglans species are true walnuts. Walnut is found in the warmer temperate zones of the Northern Hemisphere, across all of Central America to the Andean region of South America. Two woods are of particular importance, the European walnut, J. regia, which has been cultivated in Europe for a long time but which comes from the mountainous regions of Southwest Asia, and the American black walnut, J. nigra from the United States and Canada. The walnut is a medium-sized tree, 20-30 meters high; it is important for its fruits and for its precious wood.
Walnut is certainly the best known and most widely used wood not only in Europe but all over the world. Obviously, it is affected by the diversity of climates and the nature of the soils where it grows, so these differences not only appear in color but also in the physical structure of the wood (greater or lesser compactness and hardness). The European species, treated here, are however quite similar to each other.
The European walnut is brownish-gray with almost black streaks and generally more variable in color than the American walnut, which is typically a uniform dark brown-purple. The grain is straight or sometimes wavy, with a medium texture. Walnut is a little lighter than beech. Sapwood and heartwood are clearly differentiated. The sapwood is whitish while the heartwood takes on gray-brown tones with darker veins which, especially in the lower part of the trunk, take on various figures, once much sought after by furniture manufacturers. Wood generally works very well, it can be sanded and finished perfectly. It offers good durability but if placed in humid environments it is easy prey for plant and animal parasites.
Wood is hard enough but not too bendable. It can be dried very well, albeit slowly, without excessive risk of cracking or twisting. Once dried it is moderately stable on site. It works easily and is appreciated for its excellent finish. It is moderately resistant to fungi.
Uses
In the industrial and artisan sectors, walnut wood is mainly used to create:
- Fine furniture.
- Luxurious car interiors.
- Inlays.
- Veneers (using a very thin piece of wood, called veneer, which covers another material, typically plywood; frames and ornamental objects).
- Bowls and musical instruments.
- Wall and ceiling cladding (in the form of slats).
Pros and Cons
- Good workability and ease of cutting, with the right tool and equipment.
- Good aptitude for finishing: it can be sanded, painted and polished.
- Mechanical resistance stable over time, provided that humid environments are avoided.
- The brown color tending to gray, with streaks that can tend to black, together with the grain, are the aesthetic characteristics that have contributed to the success of walnut wood in luxury furnishings.
- It fears humidity: not recommended for use in the open air
- Easily attacked by parasites, especially in humid environments.
- High price: domestic production is not sufficient to meet the growing market demand.
Curiosity
While boasting excellent features, the rather high price tends to limit its use. In historical periods of maximum diffusion, walnut replaced oak as a wood for luxury furniture, while nowadays there is a tendency to use mahogany more and more (we will see it shortly).
Useful Tips
How do you clean a piece of furniture or a walnut inlay? For daily maintenance it is necessary to dust the surfaces with a soft and dry cotton cloth. For monthly maintenance it is advisable to use a spray wax that gives more shine to the surfaces and removes dust.

Versatile and functional
Walnut wood is suitable for practically any furniture imaginable. The only warning is not to place walnut furniture in damp places, because in that case you could entice companies of parasites who are waiting for nothing but gnaw on your precious furniture. Almost all walnuts are easily treatable with fine finishes so even a light walnut can be made darker with a good stain.
Before I finish, I want to reassure some doubters: yes! The wood walnut is the same that makes the walnuts we eat at Christmas and which represent the main ingredient of a good walnut. In short, an all-rounder tree.
That's why he earned the blazons of the nobility!
