Where do the burrs come from which are used to make the burr wood bowls? Burrs (or burls depending where you are from) are the unusual lumps on trees. The burrs are a result of abnormal growth within the tree. The grain pattern within the burrs is full of whorls, swirls and intense figuring and the outer surface can have interesting peaks and shapes. It is the combination of unusual grain patterns, colouring and external shape that makes burrs so highly sought after when woodturning. Burrs produce something out of the ordinary in turned wooden bowls.
Burr Characteristics
The irregular grain and shape makes the woodturners task a little more difficult. However, the results make the extra effort worthwhile. Natural edge turned burr bowls either have the bark on or off. Each creates a different overall effect for the bowl. Finishes are either oil or wax. The natural edge bowls have a more rustic appeal but make something definitely unique.
Many of the native British woods produce burrs. Oak, elm and horse chestnut are more common but other species such as beech, ash, yew and sycamore also produce burrs but burrs from these trees are less common. Paul is always looking for special pieces of wood and burrs in particular but sometimes such pieces are difficult to find so availability will depend on what he has found! A few imported woods also produce burrs which are can be visually stunning.
