Appearance of Red Bloodwood Timber
The heartwood of Red Bloodwood exhibits hues from dark pink to rich red, with an interlocked grain and coarse texture. One of its defining characteristics is the presence of concentric gum veins, also known as kino veins, which add an attractive visual pattern, especially for veneers and decorative paneling. However, these veins may open during drying, making it less ideal for sawn timber applications.
Common Applications of Red Bloodwood Timber
Due to its durability and aesthetic appeal, Red Bloodwood is commonly used for poles, piles, and posts, making it ideal for in-ground and round timber applications. Its attractive grain pattern also lends itself to decorative veneers and paneling. Other uses include sleepers, fencing, and house stumps, where its natural strength and durability are valued. While it is not typically used as sawn timber due to the gum veins, it remains a popular choice for structural and decorative uses.
Workability of Red Bloodwood Timber
Red Bloodwood can be painted, stained, and polished effectively, and it glues well, though surface preparation and machining should be done immediately before use. The presence of gum veins limits its applications in sawn timber but enhances its appeal for decorative veneers. Seasoning is achievable, but there is a tendency for gum veins to open during drying, which should be considered during processing.
Origin and Availability of Red Bloodwood Timber
Kosny Timber sources Red Bloodwood from sustainably managed native forests in coastal New South Wales and Queensland. It is generally readily available, especially near its natural growth regions, ensuring a reliable supply of this unique hardwood for both structural and decorative applications.
