> GROWTH AREA
Its origin is the west and north-west of Europe, but during the years, the growth area of this tree has extended throughout Asia and Iran.

> TECHNOLOGICAL FEATURES
Its light-grey sapwood is difficult to distinguish from heartwood. Due to the twisted shape of this tree, its wood has a fine texture and generally an interlocking fibre. It has a good fire resistance; it is compact, hard but not very durable. It is sometimes treated to be preserved, even if mostly not require.

> SPECIFIC WEIGHT
At 15% of humidity it has a specific weight of 750 Kg/m3.

> DRYING METHOD
It is preferred a slow and careful drying in order to avoid the risk of degrading through splitting and warping.

> MAIN USES AND WORKING
It is difficult to work due to its characteristic hardness and the presence of the frequente controfilo. For this reason, during the years, it has been substituted by more modern materials. Nail and screw joints strongly hold but pre-drilling is recommended. It is usually used for the realisation of tools (navette per la tessitura, lavori da carradore, torchi e viti in legno), but it can also be used in replace of ebony after a dark dyeing.
