Wood affected by woodworm. Signs of woodworm usually consist of holes in the wooden item, with live infestations showing powder (faeces), known as frass, around the holes.. The size of the holes varies, but they are typically 1 to 1.5 millimetres (5 ⁄ 128 to 1 ⁄ 16 in) in diameter for the most common household species, although they can be much larger in the case of the house longhorn beet
The common furniture beetle or common house borer (Anobium punctatum) is a woodboring beetle originally from Europe [1] but now distributed worldwide. In the larval stage it bores in wood and feeds upon it. Adult Anobium punctatum measure 2.7–4.5 millimetres (0.11–0.18 in) in length.
Fragment of a broomstick affected by woodworm. Woodboring beetles are commonly detected a few years after new construction. The lumber supply may have contained wood infected with beetle eggs or larvae, and since beetle life cycles can be one or more years, several years may pass before the presence of beetles becomes noticeable.
Decayed wood is also much easier for the larvae of the deathwatch beetle to bore into which allows them to develop at a faster rate. [5] The sapwood is more nutritious and is usually attacked first, followed by heart wood that has been softened by decay. Oak (Quercus spp.) is the main host, with American oaks being more susceptible than ...
The oak timberworm is a known vector of the destructive fungus Bretziella fagacearum, which causes oak wilt. [6] Oak wilt is major cause of oak mortality in some regions and has been detected in 24 US states. [10] Oak wilt can cause rather sudden mortality in host trees due to the disruption of sap and water flow in the xylem. [11]
Furniture conservation and restoration can be divided into two general areas: structure and finish. Structure generally relates to wood and can be divided into solid, joined, and veneered wood. The finish of furniture can be painted or transparent. [1] Furniture has existed throughout all the years of human existence.
A special icing process applied to beech wood leads to results similar to those obtained with fungal decay. After the wood has been soaked, it is iced and then dried. The result is a very light wood with an almost black grain. This result, which also occurs very rarely in nature, is called ice-beech. [43] [44]
Burl wood is very hard to work with hand tools or on a lathe, because its grain is twisted and interlocked, causing it to chip and shatter unpredictably. This "wild grain" makes burl wood extremely dense and resistant to splitting, which made it valued for bowls, mallets, mauls and "beetles" or "beadles" for hammering chisels and driving wooden ...
