Natural wooden-table top defects

Natural wooden-table top „defects”. Everything you need to know. (2)

The colour, the arrangement of the rings and their position, the spread of knots, cracks, traces of pests and diseases, changes caused by fires and mechanical damage – all this contributes to the final appearance of wood and its value as a carpentry or joinery material. Each change in wood is a record of a fragment of the individual history of tree growth and its struggle with environmental factors.

Understanding wood defects: Primary and secondary influences on wood quality

Each tree, during its individual growth, experiences a variety of external influences: it is exposed to high and low temperatures, strong winds, as well as pest and human interference. The moisture content and composition of the soil on which the tree grew, stand density and composition also have a significant impact on wood quality.

All known wood “defects” are divided into two groups:

Primary “defects” – caused during the growth of the tree, including, among others, thickening, curvature in the course of the trunk, cracks, traces of pest activity, multi-core, corks, convergence or excessive knotting.

Secondary “defects” – caused by improper handling or storage of wood, including, above all, discolouration associated with the development of fungi and mould. They may also occur as a result of improper seasoning or drying. It is worth knowing that cracks and micro-cracks are also secondary defects.It is worth knowing that there is no perfect wood, each piece is unique and different. Whether a change in wood will become its disadvantage or advantage is often determined by the way the material is used, as well as the knowledge and skills of the woodworker.

From disadvantage to aesthetic advantage: The fascinating transformation of wood knots

The most obvious example of the disadvantage of wood, which in certain circumstances becomes its advantage, is knots. In the case of structural wood, knots may turn out to be disqualifying (they weaken mechanical resistance), while used in the production of furniture, in many cases, they have a positive effect on the aesthetics of finished products.

A very good example of wooden-table top “defects” are unique knots located on the tables.

The art of woodworking: Choosing the right material and recognizing its “defects”

The final effect, i.e. the appearance of finished wood products, is greatly influenced by the ability to choose the material. Bearing in mind that there is no perfect wood, it is worth making an effort to choose the best possible raw material. A small number of knots, a simple course of rings, lack of noticeable discolouration and deep mechanical damage – these are the characteristics of good quality raw material. Their influence is very specific, for example, the harmonious arrangement of the rings will provide greater dimensional stability of finished products. In the case of purchasing lumber, the key is also: appropriate humidity and the way of storage and possible preservation (protecting against pests and fungus development).
