Small cracks running parallel to grain of wood, caused chiefly by strains produced in seasoning. These are different from flexor cracks which are small cracks put into wood as a result of mechanical flexing process.
Splits in the longitudinal separation of the fibers in the veneer or that may occur at the joining of the veneer leaves.
Eggs that have a broken shell or crack in the shell but has its shell membrane intact and the contents are not leaking.
Surface ripples and cracks induced by forming.
Numerous, very fine cracks in a coating or at the surface of a metal part. Checks may appear during processing or during service and are most often associated with thermal treatment or thermal cycling. Also called check marks. checking, or heat checks.
Longitudinal separation of the fibers in wood that do not go through the whole cross section. Checks result from tension stresses during the drying process.
Splits or cracks in wood, which are ordinarily caused by seasoning. A common characteristic of genuine cherry wood pieces.
A rupture, small splits, or openings running parallel to the grain of wood, caused chiefly by strains during cutting and seasoning. (Same as Face Checking.)
Lengthwise separation of wood fibers that extends across the annual growth rings. Commonly caused by stresses during drying. Surface checks occur on flat faces of lumber and end checks occur on the ends of lumber, logs, and other wood products.
Small slits running parallel to the grain of the wood, caused chiefly by strains produced in seasoning.
Splits running along the grain in wood that occur most frequently in end grain.
