Technical Informations
Wood species available
Botanical name :
Quercus petraea L.
Local names: Roul, Galera, Gettina, Ischia
Names in other European countries: French: Rouvre, Chêne pedunculé; English (generic): Oak; Italian: Rovere europeo; German: Stieleiche, Traubeneiche; Spanish: Roble.
Origin: Origin In ancient times the common oak dominated the Po Valley in Italy but now occupies a much-reduced area. In Central and Southern Italy, the other two species are dominant. In Central and Eastern Europe, the common oak forms extensive top-quality forests.
The yellowish-white sapwood is sharply differentiated from the brown heartwood that changes to darker shades over time. The medullary rays are very obvious, especially on radial surfaces where shiny areas form. Thanks to the large pores of the spring wood, growth rings are clearly identifiable. The fresh-cut wood has a strong acid smell and blackish spots appear on it from contact with metal tools.
The drying process is slow and not very easy because it is difficult to obtain a uniform distribution of moisture through the boards, especially if they are thick. Faced with this difficulty, if use is made of hot-air ovens, collapse and localized warping are often seen.

Botanical name :
Quercus alba
Local names: White Oak
Names in other European countries: English (generic): Oak; Italian: Rovere Americano Bianco; German: Stieleiche, Traubeneiche; Spanish: Roble
Origin: Widespread throughout the eastern United States. The group of white oaks includes many species, of which about eight are marketed.
White oak is similar in color and appearance to European oak. The sapwood of American white oak is light-coloured and the heartwood is light to dark brown. White oak has mostly straight grain with more or less pronounced texture (medium to coarse) and longer medullary rays than red oak. White oak therefore has a higher-quality aspect.
Must be dried slowly; tendency to warp; some collapse and internal cracking.

Botanical name :

Provenance: Diffused in the sporadic state in the forest formations of the Castanetum and the Beechwood.
Pale white with a slight tendency to yellowish-pink, sometimes with slight blackish streaks. The wood has a fine, compact texture and generally straight grain, but it can also present wavy grain.
Occurs rapidly and well, the emergence of discolorations must be checked nevertheless. To avoid these, it is necessary to speed up the drying of the surface layers, by inserting large battens between the boards, and by good ventilation.

The thick yellowish-white sapwood is clearly differentiated from the heartwood whose primary colour is yellow with golden hues, sometimes tending to brown. Texture rather straight, the interwoven fibres make for a characteristic grain on pieces sliced into quarters. White spots caused by chalky deposits are often present.

Botanical name :
Juglans Nigra
Local names: Noce cataletto, black walnut, american walnut
Names in other European countries: French: Noyer; Italian: Noce nazionale; German: Nussbaum; Spanish: Nogal
Origin: Widespread throughout the eastern United States.
The sapwood of walnut is creamy-white while the heartwood is from light to dark chocolate-brown, sometimes with a purplish cast and darker streaks. Walnut can be supplied as natural or evaporative so as to darken the sapwood. The grain is generally straight, sometimes with sinuous or curly forms that produce a variegated and decorative design. The heartwood, dark in colour, tends to lighten over time on exposure to ultraviolet light.
Slow drying improves performance, reducing the possibility of degradation. This wood has good stability.
