Tan Bark

Water containing tannin acid in Oak logs which causes very dark coloring. Moreover, Oak bark is also not suitable for mulching because of its high tannin acid content.

Tegernsee Custom

A recognized standard work used by the wood industry in Germany in which the general regulations for the sawing and veneer industries are laid down (i.e. quality designations for sawn timber, tolerances regarding veneer thickness and leaves with defects, etc.).

Tension

Differences in density occur in a trunk through different growth zones and growth speeds (weatherside) which can lead to tension in the log. When a tree is felled, cracking as a result of tension can occur making its use as veneer questionable. Problem especially with Beech.

Thick Cut

Veneers which are produced in other thicknesses than those laid down in the DIN Standard. Usual thicknesses are 0.9 mm, 1.2 mm, 1.5 mm, 2.0 mm and 2.5 mm. Larger thicknesses are usually produced as sawn veneers, i.e. cut on the block bandsaw.

To Grind The Knife

Small nicks and burrs on the knife blade are made smooth by using a grindstone.

To Handle

Clipping and bundling of veneers after drying in preparation for sale. Also cutting out defects and clipping to length.

To Open

→ To split

To Sort

Cutting a log to the required length and/or the desired method of slicing.

To Split

The cutting out of the heart of a log when defects or rough patches occur during slicing.

Top End

Top end of a log (trunk or veneers).

Top Grade Log

Used to express a particularly high quality of a log.

Tree Burl

Burl wood in which the burl is developed above ground in the tree. Such burls are Oak, Ash, Poplar, Elm.

True Quartier

The cutting of the log into four quarters. In the case of Oak this gives a higher portion of veneers with fine flakes. However, the yield is generally smaller than when converting in other ways.

Turning Verneers

The presentation of a log which is shown bundle by bundle.

Twist

Spiral-shaped growth of a tree caused by external influences, for example, wind. Slicing problems can occur through the annual rings breaking away from each other thus causing open spots where the spiral grain is strongly twisted.
