Sap

The outer cell layer of the wood between bark and heartwood. The supply of water and nutrients to the tree is only through the outer row of sap cells. The remaining layers of cells in the sapwood only serve to store water. Color offset in sapwood. The sapwood is cut away in veneers.

Scratch

A notch which runs across the veneer leaf caused by a faulty knife. Typical slicing fault which makes the further use of the veneer questionable. Fine knife scratches are eliminated by grinding the knife.

Sequence

The sequence of veneer leaves within a bundle and the complete log.

Shake

Cracks in the lumber which follow the course of the annual rings. Part of trunks with this defect are not suitable for producing veneer or sawn timber.

Short Length

Log and veneer between 0.80 m and 2.00 m in length.

Single Bundles

Bundles of veneer taken out of their regular sequence within the log so that the sequence is no longer given. Generally lower qualities or quarters.

Slab

First side board of the round trunk which is cut off when preparing for slicing, generally used for firing or as waste wood.

Slip Match

A method of further processing veneers by which the consecutive leaves are only glued with the front side.

Slip Verneers

Stacked in Log Form

The presentation of veneers stacked in their original log form.

Stain

Color changes in the log when same has been stored too long. Direct radiation from the sun or too dry an atmosphere furthers this development. This is why logs for storage are waxed on the ends or sprinkled with water to avoid this development.

Starter Bundles

The first bundles cut from a log.

Stay-Log

Special veneer cutting machine in which the line of cut sweeps across the growth rings in a circular direction to give eccentric cutting.

Stripy

More or less clearly contrasting color stripes in the veneer which are generally considered as degrading. Known above all in the European Oak.
