Figure in wood is determined largely by the part of the tree from which the veneer is cut. There are four (4) major sections used for veneers. 1. LONGWOOD - the trunk of the tree, is the part that begins just above the stump and continues to just below the crotch. Most veneers are cut from longwood by quarter, rotary, or flat cutting. 2. CROTCH VENEER - produced from the portion of the tree just below the point where it forks into two limbs. The grain is twisted, creating a variety of flame figures. Often resembling a well-formed feather. The outside of the block produces a swirl figure that changes to full crotch flame figure as the cutting approaches the center of the block. 3. STUMP VENEER - produced from the base of the tree. Here the grain pattern is always swirly, twisted, and often accompanied by cross fire and patches of burl. The sizes are normally small. 4. BURL VENEER
- produced from a large, wart-like growth on the trunk of the tree.
The grain pattern typically resembles a series of eyes laid side by
side. Obviously the veneers leaf sizes are generally small and additionally
are defective. While producing beautiful patterns, Burl veneer is difficult
to work with. |
of the Egyptians, about 3,500 years ago. Down through the years and cultures veneering has enriched furniture and architectural interiors with sheets of rare and beautiful woods bonded to other plain, sturdy wood based substrates to form a panel. The art of veneering is simply shaving a thin slice of wood from a log, rather than sawing a heavy board. The original veneering equipment was undoubtedly a crude saw. In fact, some veneer saws are still in use, but most have been replaced by knives. Use of knife eliminates the waste which a saw produces and increases the "yield" of a log. Today this is important both in terms of economics and conservation. In the fancy veneer industry logs are produced and manufactures as individuals. The resulting veneer is sold on an individual basis with the criteria being quality and esthetics. There are veneers
from hardwood, which are generally considered to be the broad leaved
tree species, and softwoods, which are the needle bearers. There are
estimated to some 90,000 different species under the broad heading of
"HARDWOODS". Of these, only about 100 have ever been used
economically in the fancy veneer industry. |
