English brown oak sawn timber

English brown oak takes its colour from a fungus, Fistulina hepatica, which attacks the roots of the trees, causing the wood to assume a chocolate brown hue which often appears as streaks rising up from the base of the tree and tapering out further up the trunk.

The true brown oak is unique to British forests, while in continental Europe the effect of the fungus is similar but the oak turns pink rather than brown.

The decaying effects of the fungus do not persist after the wood has been dried so brown oak can be treated in much the same way as any normal coloured oak.

Appearance
Waney edge boards of English oak will be supplied with wane (bark) on one or two edges.

English brown oak is similar in every way to normal English oak except for its colour. The grades range from First Joinery to Character although there is rarely enough volume to sell the grades separately.

At least half of each board will be either solid chocolate brown or streaky, with the remainder being the normal oak colour. Boards which are solid brown from end to end are very rare and consequently in great demand.

The centre (quarter sawn) boards will include the heart which often takes the form of a crack running down the centre of the board. The silver medullary rays displayed on the quarter sawn boards provide a stunning contrast to the brown colour.

The bottom end of a brown plank will often be decayed past the point of usefulness. This section will either be removed or, if there is some useful wood present, a suitable reduction in measure will be applied.

English brown oak is prone to surface splits, especially near the centre of the log. Excessive splitting will be measured out.

To avoid disappointment please make an appointment before arriving at either yard to select sawn timber.
