Description

Burmese Teak heartwood is a uniform golden brown without markings. Grain is usually straight to slightly wavy. Texture is coarse, uneven and oily to the touch, sometimes with a white glistening deposit.
Weight varies from about 38lbs to 43lbs per cu. ft.

 

Mechanical Properties

Medium bending and high crush strength. Low stiffness and resistance to shock. Fissile and brittle with great dimensional stability. Moderate steam bending characteristics.

Working Properties

Medium resistance to cutting tools with a severe blunting effect. Pre-drilling required for nailing. Gluing is good on freshly planed or sanded surfaces. Fine machine dust is a skin irritant. Stains well and takes a satisfactory finish, especially an oil finish.

Durability

Very durable. Susceptible to insect attack. Extremely resistant to preservative treatment.

Seasoning

Dries well, but slowly. Variations in drying rates can occur in individual pieces. Standing trees are girdled and left to dry for three years before felling. Small movement.

Heartwood Colour

The heartwood in its purest form, is a uniform dark golden-brown, without markings. But most other heartwood found in this species is dark golden yellow, which turns into rich brown with darker, chocolate-brown markings upon exposure. There is moderate to high color variation between boards. Often very variable in color when freshly machined showing blotches and streaks of various shades. After exposure to light the wood will tone down to the golden-brown shade.
