Timber Species: Turpentine (Syncarpia glomulifera)
Dry Density: 930 kg/m³
Janka Hardness: 12 kN
These properties are only a guide, as timber is a natural product there will be variations within any species. The Janka Dry Hardness rating measures the hardness of the wood. The higher the number the harder the wood.
Native to New South Wales and Greenland, the turpentine tree is, strangely enough, not used as a source for turpentine oil – it simply shares a name thanks to the smell of turpentine released when its leaves are crushed. Reaching as high as 60 meters and routinely growing on heavier soils, turpentine is a large, straight-trunked tree with a trunk diameter that can approach 1.5 meters. Its thick bark is fibrous and dark brown with deep vertical furrows, and the tree produces cream-coloured flowers from August through December.
Thought to be able to live for up to 500 years, turpentine trees are popular with pollinators like native and European honeybees, the grey flying fox, the little red flying fox, and bird species such as the noisy miner and rainbow lorikeet. Turpentine commonly grows alongside other popular timber trees such as the grey ironbark, the tallowwood, the brush box, the spotted gum, and others.
Turpentine timber is highly resistant to termites and marine invertebrates, incredibly durable thanks to its Janka hardness rating of 12, and is highly resistant to fire. Hardy and adaptable, turpentine trees make for excellent shade in park settings, and the colour of its timber – which vacillates from deep chocolate brown tones to pale to dark reddish browns. Its coarse yet even texture and straight grain makes it ideal for solid timber flooring and parquetry, and its extreme durability makes it a natural for decking as well.
