Parana Pine
 Parana Pine (Araucaria angustifolia)
|
Common Name(s): Parana Pine Scientific Name: Araucaria angustifolia Distribution: Southern Brazil Tree Size: 65-115 ft (20-35 m) tall, 2-3 ft (.6-1 m) trunk diameter Average Dried Weight: 34 lbs/ft3 (545 kg/m3) Specific Gravity (Basic, 12% MC): .42, .54 Janka Hardness: 810 lbf (3,610 N) Modulus of Rupture: 13,390 lbf/in2 (92.3 MPa) Elastic Modulus: 1,648,000 lbf/in2 (11.37 GPa) Crushing Strength: 7,570 lbf/in2 (52.2 MPa) Shrinkage: Radial: 3.8%, Tangential: 7.4%, Volumetric: 11.6%, T/R Ratio: 1.9 |
Color/Appearance: Heartwood is light to medium brown, commonly with red streaks. Sapwood is yellow.
Grain/Texture: Grain is straight, with a uniform medium texture and low natural luster.
Endgrain: Resin canals absent; earlywood to latewood transition gradual, color contrast low; tracheid diameter medium-large.
Rot Resistance: Rated as non-durable to perishable; poor insect resistance.
Workability: Easy to work with hand or machine tools. However, Parana Pine has a tendency to warp and distort during drying, and compression wood may be present in the wood, which cause boards to further distort after ripping or resawing. Glues and finishes well.
Odor: No characteristic odor.
Allergies/Toxicity: Although severe reactions are quite uncommon, wood in the Araucaria genus has been reported to cause skin irritation. See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information.
Pricing/Availability: Extensively logged in the past, Parana Pine is very seldom available. Expect prices to be much higher than comparable domestic softwoods.
Sustainability: This wood species is not listed in the CITES Appendices, but is on the IUCN Red List. It is listed as critically endangered due to a population reduction of over 80% in the past three generations, caused by a decline in its natural range, and exploitation.
Common Uses: Veneer, furniture, flooring, and interior millwork.
Comments: So named for the Brazilian state of Parana, where the wood has been heavily exploited in the past.
Scans/Pictures: A special thanks to Steve Earis for providing the wood sample of this wood species.

Norfolk Island Pine
 Norfolk Island Pine (Araucaria heterophylla)
|
Common Name(s): Norfolk Island Pine Scientific Name: Araucaria heterophylla Distribution: Endemic to Norfolk Island (also planted as an ornamental tree) Tree Size: 165-230 ft (50-70 m) tall, 4-6 ft (1.2-1.8 m) trunk diameter Average Dried Weight: 31 lbs/ft3 (495 kg/m3) Specific Gravity (Basic, 12% MC): .43, .50 Janka Hardness: 650 lbf (2,890 N) Modulus of Rupture: 11,730 lbf/in2 (80.9 MPa) Elastic Modulus: 1,723,000 lbf/in2 (11.89 GPa) Crushing Strength: 6,420 lbf/in2 (44.3 MPa) Shrinkage: Radial: 3.5%, Tangential: 5.3%, Volumetric: 8.9%, T/R Ratio: 1.5 |
Color/Appearance: Heartwood is light brown, sometimes with a yellow or red hue. Paler sapwood isn’t clearly defined. Sometimes afflicted with blue/gray fungal staining, particularly if not dried properly. (In certain applications this staining is considered decorative, particularly when the wood also features contrasting reddish knots.)
Grain/Texture: Grain is usually straight, with a fine to medium uniform texture. Moderate natural luster.
Endgrain: Resin canals absent; earlywood to latewood transition gradual, color contrast low; tracheid diameter medium-large.
Rot Resistance: Rated as non-durable to perishable; poor insect resistance. Also susceptible to fungal staining.
Workability: Clear sections of wood are easy to work with hand and machine tools. Sections with knots can be problematic and result in tearout or uneven sanding due to the difference in density of the two regions. Glues, finishes, and turns well.
Odor: No characteristic odor.
Allergies/Toxicity: Although severe reactions are quite uncommon, wood in the Araucaria genus has been reported to cause skin irritation. See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information.
Pricing/Availability: Not generally harvested within its native range, occasional turning blanks and short craft lumber is available in areas where the tree has been planted as an ornamental. Expect prices to be in medium to high for an imported softwood.
Sustainability: This wood species is not listed in the CITES Appendices, but is on the IUCN Red List. It is listed as vulnerable due to a very restricted area of occupancy and/or number of locations.
Common Uses: Furniture, plywood, paper (pulpwood), turned objects, and small specialty wood items.
Comments: This species is only found on Norfolk Island, a small island about 900 miles east of Australia. Although the common name indicates this species is a pine, it’s not technically a true pine in the Pinus genus, which is essentially restricted to the northern hemisphere. However, Norfolk Island Pine is a member of the Araucaria genus, which could be considered a southern hemisphere counterpart to the Pinus genus.

Baltic Birch
Baltic Birch is not a specific species of birch, but is a general designation of plywood from Russia and nearby Baltic states (such as Finland). As with any natural wood product, quality can be variable. However, Baltic Birch plywood is generally regarded as being of higher quality than standard birch plywood.
In a nutshell, Baltic Birch plywood is made entirely from birch plies, with no softwood or filler plies in the center. Furthermore, the plies themselves tend to be much thinner, allowing for more plies for a given thickness, and greater stiffness and stability.
 Baltic Birch (plywood) |
 Baltic Birch (plug) |
Baltic Birch grades
The grading for Baltic Birch is established by the Russian intergovernmental standard GOST 3916.1-96.
Grading is given as the two outer faces of the plywood, in the format of [front/back]. For instance, baltic birch with a “B/BB” grade would have a B grade front ply, and a BB grade back ply.
A: Nearly perfect and flawless face veneer ply. This grade is no longer available commercially. (Also designated grade “E” according to GOST 3916.1-96.)
B: Generally uniform light color, with no plugs, or open cracks/splits. A limited amount of pin knots, and minor color inconsistencies are allowed. (Also designated grade “I” according to GOST 3916.1-96.)
BB: Generally uniform color, though color variations/stains are allowed. Limited amount of plugs, cracks/splits, and unlimited amount of pin knots allowed. (Also designated grade “II” according to GOST 3916.1-96.)
CP: Generally less consistent color, more prevalent defects (knots, staining, etc.), and an unlimited amount of plugs. (Also designated grade “III” according to GOST 3916.1-96.)
C: Utility grade; inconsistent color with mineral staining, cracks/splits, larger knots, etc. (Also designated grade “IV” according to GOST 3916.1-96.)
