A new approach on conservation of wooden heritage
2004 - IRG/WP 04-40291
Biodeterioration of wooden art objects has to be treated in a more delicate manner than biodeterioration of wood. Any treatment applied to the art object should not alter the visual, structural or scientific integrity of the object. These requirements therefore restrict the use of biocides and some alternative treatment procedures like high and low temperatures and radiation. Fortunately, an al...

Surface Barriers for Protection of Culture and Heritage Wooden Objects from Insect Attack
2004 - IRG/WP 04-40286
Anoxic treatment is an environment friendly procedure for eradication of wood boring insects in wooden objects of cultural and historical heritage. However, after the anoxic treatment, wooden antiques remain susceptible to further insect attacks. Possible protection against insects could be provided by the so-called post-repression protective barriers. Potential coating materials for such barriers...

Cultural heritage – research into innovative solutions and methods for historic wood conservation
2016 - IRG/WP 16-10874
Nowadays, interdisciplinary knowledge, tools and techniques are increasingly used to protect and conserve monuments representing our cultural heritage. This is of great importance especially in case of conservation and restoration of wooden historic artefacts which, as a result of physical, chemical and biological corrosion, have lost their technical, aesthetic and decorative properties. If those ...

Assessment of the condition of wooden mill in the area of Kovačevići in Bosnia and Herzegovina
2023 - IRG/WP 23-11030
An excellent example of cultural and technical heritage is almost 100 year old wooden mills near Cazin in Bosnia and Herzegovina. These mills played an important role, especially in times of Bosnian war (1992-95), when this region was cut off from electricity. The laboratory analysis revealed that the respective mill was made of chestnut (Castanea sativa) and oak (Quercus sp.) wood. The sufficient...

Microbiological degradation of wooden piles in building foundations
1988 - IRG/WP 1370
White rot, soft rot and bacterial attack have been detected in softwood piles under buildings. In some cases bacteria were found to be the main degradation organisms in the studied piles. The water content of degraded piles was very high. The compression strength was quite low also in the piles deteriorated by bacteria. The density of wood was very variable, and the degree of degradation could not...

Conservation of wooden cultural property
1994 - IRG/WP 94-30038
A survey of the conservation of wooden archtitectual monuments, art objects and archaeological finds is presented. Each of the three areas has typical conservation problems which reqire the use of selected wood preservatives and consolidation agents. Furthermore specific protection and consolidation methods are necessary. A precise damage diagnosis with non-destructive testing methods is the first...

Finite element analysis of boron diffusion in wooden poles
2003 - IRG/WP 03-40263
The problem of describing the migration of dissolved boron in wood is treated with special reference to the commonly used remedial treatment of wooden poles. The governing equations are derived and discussed together with some of the material parameters required. The equations are solved by the finite element method and finally, results showing the effect of different treatment strategies are pres...

An approach to testing the preventive effectiveness of preservative treatments for wooden joinery
1981 - IRG/WP 2156
The ecological sequence established in field trial samples exposed out of ground contact has shown the need for outdoor exposure in testing potential joinery preservative pretreatments. A system of exposure of L-joint units is proposed. Data obtained by examining samples destructively show promise as the basis for predicting service life after relatively short exposure periods (within 2 years)....

The effect of service life and preservative treatment on the hardness of wooden poles
1989 - IRG/WP 3537
The surface hardness of utility poles is an important parameter which effects the acceptability of the pole as being safe to climb during line maintenance. The current investigation was designed to evaluate how the surface hardness of preservative treated utility poles is effected by the type of preservative, and the age of the poles. Chromated-copper-arsenate (CCA) treated red pine and jack pine ...

Analysis of degradation observed on ancient wooden objects buried underground
2001 - IRG/WP 01-10403
Ancient wooden objects were sometimes excavated from the moat of mounded tombs in Japan. Such wooden objects were in the shape of a sunshade, bird, shield, pole, yugi(a bag that holds arrows) among others. Archaeologists discussed the usage of such shaped objects, but no one could clearly explain their use. Some objects were observed using an ordinary microscope. Deterioration by bacteria was foun...
