Solid wood: The typical properties
of processed planks for building furniture
Solid wood is a true natural product, each piece is unique in terms of its structure and colour. Fine branches, cracks, intergrown areas and merging structures underline the materials' authenticity. Characterised by the location of the tree as well as the weather and soil conditions, each piece of solid wood is a genuine, unique product of nature. Solid wood has a pleasant feel - it feels good, it has a pleasant smell and it imparts a healthy living environment. Solid wood furniture creates an ideal living atmosphere. The material has antibacterial properties and prevents electrostatic dust charges. It helps counteract allergies, contains no harmful substances and is a natural product. Our raw material, wood, comes exclusively from sustainably managed forestry. Our solid wood furniture ensures the best possible indoor atmosphere, is good for allergy sufferers, pollutant-free and natural.
Solid beech heartwood
Our beech heartwood comes from the heart of the beech trunk with partially truncated piths. The brown-coloured edge of the piths characterises the heartwood planks. Beech heartwood is a hardwood with a tendency to "warp", even after professional processing.
The surface of beech wood remains relatively stable in terms of colour, however it can become more yellowish depending on the intensity of the light.
Natural oak heartwood
Our natural oak heartwood exclusively consists of heartwood planks made from oak trunks as only this type of wood provides the desired, typical properties, such as heartwood splits and splay knots.
Tobacco oak heartwood
The brownish tobacco stain intensifies the strong character of the core oak. Like the natural core oak, the tobacco of the core oak also consists exclusively of the core boards of the oak trunk and has the typical characteristics such as core cracks and wing knots.
For manufacturing our Umato heartwood oak surfaces, planks of wood are first selected from the heartwood area of the oak trunk. These heartwood planks depict typical characteristics, e.g. heartwood splits and splay knots. The sorted product is then stored for several days before drying in a special chamber and there, it is subjected to a smoking process.
As a result, the wood is dyed and receives a uniform dark colour. The character of old oak logs emerges.
In order to maintain the character of a wood surface marked by wind and weather, the wood surfaces are first blasted with a special granulate. This will remove the soft parts of the wood surface, making them extremely rough.
With a brushing machine and by hand, these surfaces are smoothed and coated with water-based paint and wax.
Solid tannin oak
Tannin oak has a striking, brownish, strong and expressive grain. Small branches and an ethnic play of colours make this wood unique.
The special constituents of the oak, the tannins, accumulate on the surface of the wood during drying. The evaporated liquid forms a special, unmistakable pattern - the tannin clouds.
Hartmann uses a specially selected American walnut. It is characterised by their strong natural characteristics, such as misshapen branches and cavities as well as cracks throughout the heartwood.
These natural features are carefully sorted and contribute to the aesthetic effect.
