Environmental Profile
The environmental status of this species within its geographical range has not been officially determined.
Distribution
Species in the Myristica genus are
reported to be distributed in the Indo-Malayan region,
Product Sources
It is currently unknown whether material from this species
is available from sustainably managed, recycled,
salvaged, or other environmentally responsible sources.
Tree Data
Mature Myristica trees are
reported to vary in size from medium to large. They usually attain a height of
60 to 90 feet (18 to 27 m), with a trunk diameter of 12 to 30 inches (30 to 75
cm) over occasional and medium-sized buttresses. Boles are often straight and
of good form.
Sapwood Color
The sapwood is lighter in color than the heartwood and is
not clearly demarcated.
Heartwood Color
The heartwood is light reddish brown, dull brown,
brownish-gray or olive-gray in color.
Grain
The grain is typically straight.
Texture
Texture is described as rather fine to slightly coarse.
Odor
There is no distinctive odor or taste.
Ease of Drying
The timber is reported to dry rather slowly with little
degrade.
Drying Defects
Thinner material may warp during drying.
Kiln Schedules
T10 - D4S (4/4) US
Movement in Service
The wood is reported to exhibit medium movement after
manufacture.
T/R Ratio
Natural Durability
The heartwood is reported to be susceptible to attack by
termites and decay fungi. The sapwood is vulnerable to powder-post beetle
attack.
Resistance to Impregnation
The timber is reported to respond readily to preservative
treatment.
Veneering
Selected European lime logs are reported to be sliced into
veneers for decorative applications. Plywood resistance to weathering effects
upon exposure is reported to be good.
Blunting
The wood has slight dulling effect on cutters.
Resistance to Cutting
Cutting resistance is rather low, and the timber is reported
to saw without difficulty.
Planning
The timber planes easily with ordinary tools to yield clean
surfaces.
Turning
Turning operations are reported to be very easy.
Boring
Boring properties are reported to be very good.
Routing and Recessing
The wood routs and recesses easily.
Mortising
Mortising operations are reported to be good.
Moulding
The timber is reported to mould easily with ordinary tools.
Carving
European lime is reported to be well suited for carving
since has high resistance to splitting when cut in any direction.
Gluing
The timber is reported to respond well to gluing.
Nailing
Nailing properties are reported to be rather poor. The
timber tends to split in nailing.
Screwing
Sanding
The timber is reported to have good sanding properties.
Polishing
Polishing characteristics are reported to be good.
Staining
The timber is reported to respond well to most finishes.
Painting
Steam Bending
The timber is reported to be suitable for bends of moderate
radius. Steam bending qualities are rated as moderate and cannot be improved to
any degree with supports and straps.
Response to Hand Tools
The timber responds very well to hand tools.
Strength Properties
Bending strength in the air-dried condition (about 12% moisture content) is medium, but lower than Mahogany, and much lower than White oak. Its strength in compression parallel to grain is medium, but ower than that of Teak. It is not hard and can be dented and marred easily. It is of average, or medium, density.
