How A Tree is Cut Affects The Way Your Glasses Will Look
Burr or Burl Wood
Truth is, nobody really knows what causes a burr to form. It is basically a bacteria or ‘abnormality’ and is usually a result of some kind of stress on the tree. It grows mainly underground and so is usually discovered after the three is cut or dies, but does also grow on the trunk and branch of the tree. However, it produces something of incredible beauty which is highly sought after by all cabinet makers. A pair of glasses made form Walnut burr or any burr will look particularly elegant.
Rolls Royce, Bentley and other high end car manufacturers will normally use a burr for the dashboards and trims. They are of course much more expensive than all other cuts.
Quarter Sawn – Quarter Cut
Most woods are available as quarter sawn. This is simply the way the log is cut after is is felled, and is cut in such a way as to produce a very straight grain. Its is also a very expensive way to cut a log as there is a lot of wastage. However the very straight grain is the most stable cut, and although not important in the production of engineered eye wear, it is important in the manufacture of things like flooring and furniture.
Crown Sawn – Plain Sawn
This is by far the most popular and cost effective way of cutting a log. However, it is not a particularly exciting cut to use in the production of eye wear as there is more often than not very little action going on in the grain for such a small item as glasses. However, if we do use crown sawn we only select woods that have a flamboyant grain pattern e.g Santos Rosewood, Macassar Ebony and Ziracote. All these woods have interesting crown sawn figuration so they are all suitable for the production of Campbell Marson glasses.
