Bayur or Wadang Burl (Pterospermum javanicum) is the burl wood, rarely available on the international timber market, of a tree growing in Indonesia, especially on the east coast of Java, which has been spread to other Southeast Asian countries, where it is called Nwalabyin (Myanmar), Melerang or Letop-letop (Sabah, Malaysia). The tree grows to a height of about 30-45 meters, often grows crooked and spindly, becomes about 100 cm thick and its wood is medium hard and medium heavy, about 600 - 700 kg/m3. It is often descriptively called redburl wood because of its unfamiliarity.
The wood occurs in huge burls, which can often reach 1.50 meters in diameter, and is always finely and evenly grained, showing fine swirls, eyes, dormant buds and wild structures. Due to its fine structure, the wood is easy to work and will surprise any woodworker with its silky sheen and attractive red color after an application of oils!
Small imperfections typical of burl wood, such as bark ingrowths, pin knots, swirls, hairline cracks and the like, can be filled easily and very quickly with thin-bodied super glue.
