Northern Silky Oak

Northern Silky Oak (Cardwellia sublimis), also known as Silky Oak or Australian Lacewood, is a highly decorative hardwood found in northern Australia. It is renowned for its distinctive grain pattern, which features a lace-like figure due to its prominent medullary rays. The heartwood varies from light golden brown to rich reddish-brown, with a medium to coarse texture and interlocked grain.

​

The timber is moderately durable, naturally resistant to termites, and has good stability, making it suitable for furniture making, cabinetry, and veneers. Northern Silky Oak is relatively easy to work with, responding well to machining, sanding, and finishing, which enhances its characteristic shimmering appearance. Its eye-catching grain makes it a popular choice for feature panels, high-end joinery, and decorative applications.
