Wood species available

Botanical name American White Oak:
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.

European Ash
Botanical name:
Fraxinus excelsior L. and Fraxinus Ornus L.

Local designations: Fraissu, Lusa, Fersena, Frosso, Frascinu, Orniello

Denominations other European countries: French: Frene; English: Ash; German: Bait; Spanish: Fresno.
Provenance: In Italy and in Europe (excluding the northern end) present sporadically in the mixed hardwood formations, from the plain to the Middle Mountain.


The sapwood of whitish yellowish color differs from the slightly darker heartwood: sometimes a central blackish zone appears, with irregular boundary (olive ash) presumably caused by fungal attacks. The radial surfaces appear of pearly gloss thanks to the numerous and very fine medullary rays.

The drying process is quite easy, but in its course there can be serious deformation: it is therefore necessary to proceed with prudence and at the end to undergo a good reconditioning to the saats.

Names in other European countries: Sapelli, Sipo, Sapele

Provenienza:
Rainforests and the edges of the savannah on the tropical equatorial belt that runs from Sierra Leone to the Central African Republic and the Congo Basin, with an easterly extension into Uganda


The thin sapwood varies in colour from whitish to pinkish-grey and is clearly differentiated from the reddish-brown or violet heartwood. Contact with metals may cause dark spots. Narrow texture; interwoven grain; stripe pattern on wood sliced into quarters; tangential cuts reveal pronounced growth rings. When recently cut, smells like cedar. When recently cut, smells like cedar.

Should be dried with care; seasoning needed to avoid warping

Botanical name iroko:
Chlorophora excelsa Benth. & Hook. F., C. Regia A. Chev.

Local names: Abang, Kambala, Odum, Intule, Rokko, Moreira

Names in other European countries: Francia, Germania, R.U.: lroko ma, erroneamente, anche Chène d’Afrique, African Teak

provenance:
Equatorial forests of the countries surrounding the Gulf of Guinea: The second mentioned species is present in the eastern area, from Ethiopia to Mozambique


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. Good resistance to acid and fire. Iroko is sometimes compared to teak.
