Base Moulding:

A moulding applied where the floor and wall meet, forming a visual foundation. A base protects walls from kicks, bumps, furniture, and cleaning tools. A base may be referred to as one, two, or three member. The base shoe and base cap are used to conceal uneven floor and wall junctions. Also when a relatively small moulding is applied to the top of the base with a two-member base it forms a three member base.

Bark:

Areas of fiber from outside a tree.

Bevel:

Machine angle other than a right angle. That is, a 3-degree bevel which is equivalent to a 1/8-in. drop in a 2-in. span.

Beveled edge:

Edge of a door which forms an angle of less than 90 degrees with the wide face of the door, such as a 3-degree beveled edge.

Blister:

Spot or area where veneer does not adhere.

Book size:

The height and width of a door before prefitting.

Brashness:

Condition of wood characterized by low resistance to shock and by abrupt failure across the grain without splintering.

Burl:

Swirl or twist in grain of wood, which usually occurs near a knot but does not contain a knot.

Butt joint:

Joint formed by square edge surfaces (ends, edges, faces) coming together.

Chalk:

White or other color chalk marks used by mills for some form of identification marking defects for repair.

Chatter:

Lines appearing across the panel at right angles to the grain giving the appearance of one or more corrugations resulting from bad setting of sanding equipment.

Chicken tracks:

Expression for scars which give the particular effect of a chicken`s footprint. It is caused by air roots or vines.

Clustered:

When a defect described in the grading rule is sufficient in number and sufficiently close together to appear to be concentrated in one area.

Composition face panels:

A door face panel made of a wood derivative.

Core:

Innermost layer of section in flush door construction. Types of construction include: wood block; particleboard; wood block (lined); hollow; ladder; mesh or cellular.

Core (Wood Block):

Solid core of wood blocks or strips

Core (Particleboard):

Sold core of wood or other lignocellulose particles bonded together, cured under heat, and pressed into a rigid panel.

Core (Wood Block, Lined):

Solid core of two parts: a central wood block core bonded to two core liners of wood or other lignocellulose materials.

Core (Hollow):

Core assembly of strips or other units of wood, wood derivative, or insulation board, with intervening hollow cells or spaces which support outer faces.

Core (Ladder):

Hollow core composed of strips of wood, wood derivative, or insulation board with the strips running either horizontally or vertically throughout the core area with air cells and/or spaces between the strips and supporting the door faces.

Core (Mesh or Cellular):

Hollow core composed of strips of wood, wood derivative, or insulation board, interlocked and running horizontally, vertically, or diagonally throughout the core area with air cells and/or spaces betwe en the strips and supporting the outer faces.

Crossbanding:

Veneer placed between the core and face veneers of plywood face panels of wood flush doors in which the direction of the grain in 2-ply construction is at right angles to that of the face veneer.

Cross bar:

Type of figure or irregularity of grain resembling a dip in the grain, running at right angles, or nearly so, to the length of the veneer.

Cross break:

Separation of wood cells across the grain.
