Appearance:
Europe till Asia Minor; both species of oak are missing in middle and north of Scandinavia, completely in Finland, west, middle and south of Spain, both species mostly in hardwood mixed forests, also alone standing, quiet often in grassland and parks, rarely in the roadside; highest appearance in France; second important hardwood in Europe, trees grow in light, become very old (500...800 years)
Advices:
Wood with narrow annual year rings - preferred for veneering; questioned provenance: "Spessart oak", Slovenian oak; concerning to the width of the annual year rings, the following terms of hardness exist: < 1 mm = mild wood, 1...2 mm half mild wood, 2...3 mm medium hard wood, > 3 mm = hard wood; they influence the processing; chopping in winter and intensive protection of logs is absolutely necessary; cutting without bark, careful stacking, it is required to protect the cross-section and avoid the access of water.
In trade you can also find veneering with the texture of pyramid and maser for the first-class interior fitting, for the European timber industry there are 20 till 30 species of red- and white oak of a very high importance. The word-wide biggest growing area for cork oak is Portugal (67 000 hectares!).
| Working Properties: |
|
The working and machining properties of oak vary with the mild to tough material which either machines easily or with moderate difficulty depending upon growth areas. The wood can be stained polished, waxed and glued satisfactorily. Also takes liming and fuming treatments well.
|
| Physical Properties: |
|
The wood is hard and heavy with good strength properties, in particular its high resistance to abrasion and wear. It also has good steam bending properties.
|
| Main Uses: |
|
Oak dries slowly with a marked tendency to split and check, particularly in thicker sizes. Will honeycomb if the drying is forced. Untreated iron will stain oak blue-black. Also the acidic nature of oak will accelerate the corrosion of metals.
