Cancer

A disease of the European Oak which destroys the structure in the veneer and appears as open defect in advanced stadium. Very difficult to recognize in the bark.

Cathedral Structure

Much sought after structure in crown cut bundles.

Chatter Marks

Deviation in veneer thickness caused through vibration of the veneer block on the slicing machine or by wrong pressure setting on the machine, showing on the veneer leaf as regularly distributed cross running strips. The veneer block vibrates when the log is not firmly clamped flat on the cutting table.

Clipping

The clipping of veneers on the veneer cutter whether the veneers are in their initial or in final production.

Cluster

Only partially burled logs.

Complete Flitch

Veneers which are not only produced from one log but where all leaves remain in their exact original log sequence.

Compression Wood

The zones given in soft wood through irregular annual ring structure
which are particularly hard and, therefore, cause difficulties when
slicing the veneer.

Condensate

The tannic acid which is yellow in color and deposits on the surface of the veneer when it is dried too sharply.

Cross Grain

Buckling of the veneers given through irregular growth or through logs under high tension. It shows itself also as darker coloring down the annual rings.

Crotch

Crotch veneer figuring sometimes termed “curl” which is manufactured from the intersection of the limb or branch with the main trunk (see page 273). The quality is all the better the more precise and distinct the curl or crotch and feather are.

Crown Cut

The first bundles from a log when sliced over the heart. Produces the so-called cathedral structure.

Curl Fishbone Figure

Typical figure development especially in beech which is generally considered to be degrading.
