Family: Lauraceae
ATIBT Standard Name: Canela
Other Name: Pisie, Caraiou,
Caneio, Louro Branco, Inamui, Preto
Wood Appearance: The heartwood
ranges from greyish through yellowish buff to light brown and
darkens on exposure. The wood usually has a pleasant aromatic
odour.
- Sapwood -
- Texture - rather fine to moderately coarse. Lustre medium
to high
- Grain - straight, occasionally somewhat roey.
- Bole - 60-70 feet long, diameter 16-24 inches.
Physical and Mechanical Properties:
In Guyana the Silverballi group is divided into "hard and
soft" with the dividing line being put at an air dry
specific gravity of 37 lb/ft3. The "hard" Silverballi
is rather light to heavy with densities ranging from 37-62 lb
per cu. ft. "Soft" Silverballi ranges in densities from
22-37 lb per cu ft. The group is generally in strength class 2.
Movement rather low, the lighter species shrink less than the
heavier types.
- Weight -
- Bending Strength -
- Modulus of elasticity -
- Compression parallel to grain -
- Shock resistance -
Natural Durability: Moderately
resistant to insects and decay, but susceptible to termites. Highly
resistant to marine borers. Difficult to impregnate.
Timber Processing
- Drying - Kiln Schedule G. Silverballi air dries well with
little degrade.
- Working - Saws well and works easily.
- Assembly - Holds nails, screws and glue well.
- Finishing - Finish smoothly unless grain is severly interlocked.
Paints well.
Uses: "Hard" Silverballi:
general carpentry, boat building (planking), suitable for both
interior and exterior work in house building, furniture and cabinet
work, suitable fir veneer and plywood. "Soft" Silverballi:
general carpentry, interior work, light furniture, suitable for
utility plywood.
Supplies: Occurs frequently
in the Guyana forests. Regular supplies are available for orders
place in the Silverballi groups. |
