Wood description: Oak heartwood has a yellow-brown to dark-brown colour and stands out clearly from the 25-50 mm wide pale-brown sapwood. Quarter sawn wood shows characteristic shining “mirrors”, caused by the wide rays. The wood has ring pores, which gives rise to flame markings on the face of the wood. Structure and quality vary depending on the growing conditions. Oak has a high tannin content, which means that metals corrode quickly in contact with oak.
Botanical name: Quercus petraea.
Growth area: Europe and Asia.
