| Glossary of Veneer Terms: A-F G-L M-R S-Z | |
| Grading | Classifying veneers according to quality standards for each species. This greatly impacts the price and end use of the veneer. |
| Grain | Size and arrangement of the cells and pores of the living tree. Grain is not synonymous with figure. Woods fall into three groups: Fine grained (Birch, Cherry, Maple, etc.), medium grained (Walnut, Mahogany, etc.) and coarse grained (Oak, etc.).) Coarser grained woods can usually be cut to develop a more conspicuous pattern. |
| Gum | Patches or black spots occurring primarily in American Cherry. This undesirable characteristic is acceptable in varying degree in most grades of Cherry. |
| Half Round Slicing |
Similar to rotary peeling, also producing a high veneer yield. Used primarily to add width to narrow stocks by increasing the plane of cut. Also used to enhance a particularly wild grain pattern. Matching is possible because the leaves can be kept in sequence. Half round cutting may be used to achieve "flat cut" veneer appearance. |
| Hardwood | General term used to designate lumber or veneer produced from broad-leafed or deciduous trees in contrast to softwood, which is produced from evergreens or coniferous trees. |
| Heartwood | The non-active center of a tree generally distinguishable from the outer portion (sapwood) by its darker color. |
| Herringbone | Veneer strips are used and matched to both sides of the center line, at an angle. The resulting appearance is reminiscent of the bones of a fish as they are attached to the back bone. |
| Holes, worm | Holes resulting from infestation of worms. |
| Joint | The line between the edges or ends of two adjacent sheets of veneer or strips of lumber in the same plane. |
| Knots, Pin | Sound knots 1/4 inch or less that do not contain dark centers. Inconspicuous or blending pin knots are barely detectable at a distance of 6' to 8', do not seriously detract from the overall appearance of the panel, and are permitted in all grades. |
| Knots, Open | Opening produced when a portion of the wood substance of a knot has dropped out, or where cross checks have occurred to produce an opening. |
| Knots, Sound, Tight | Knots that are solid across their face and fixed by growth to retain their place. |
| Lamination | The process of gluing or bonding the component sections of the plywood into a single permanent until stronger than the original wood itself. |
| Looseside | In knife-cut veneer, that side of the sheet that was in contact with the knife as the sheet was being cut. The bending of the wood at the knife edge causes cutting checks. |
