Bog oak

Sequences of bog oak have been prepared from the ancient oaks dug out of the bogs of England and Ireland by laboratories in those countries and are being analyzed in Scotland and North Ireland. 

Bog oak is wood that has been buried, usually in an anaerobic environment such as a bog or swamp. In Ireland this material is popular for carvings, often with a Celtic theme. It is used as an imitation of jet, although it is usually not black, but a dull dark brown. 

A greyish, slightly rough, matt surface that is carved suggests bog oak (Fig. 2.5).
