Description

Part of an educational set for exploring wood structure for timber grading. This is a simplfied model showing growth rings, sapwood and heartwood, and knots on the outside surface. Depending on the direction the wood is cut: appearance of the grain; knots; distribution of sapwood and heartwood; and wane. https://blogs.napier.ac.uk/cwst/3dwood/
