Australian Grey Box burl (Eucalyptus microcarpa) is also commonly known as Gum-topped Box, Inland Grey Box, and Narrow-leaved Box. Grey Box burl is from southeastern Australia. The burls grow on medium sized trees in the Eucalyptus family. The density generally ranges from .83 up to 1.1. Grey Box burls are prized for their unique figure and colors including heartwood ranging from warm medium to dark brown accented with creamy blonde to yellow sapwood. Texture ranges from medium to coarse with generally interlocked grain in burls. The wood takes a nice natural polish and is great for eye catching projects ranging from one of a kind bowls, pens, boxes, clocks, and knives to other fine articles. This is a unique species that is rare on the US market.
