Examination of timbers from the Mary Rose in storage
1988 - IRG/WP 4149
Timbers from the Tudor ship, Mary Rose, have been examined for the presence of fungal fruiting structures. Wood specimens were also examined for the presence of microbial decay patterns using light and scanning electron microscopy. Structural timbers were surveyed using the Pilodyn for an overall picture of the extent of decay. Mary Rose timbers were predominantly inhabited by marine fungi. Fourte...

Fungal colonisation of the keelson and associated structures of a nineteenth century wooden frigate: Concepts of community structure and development
1994 - IRG/WP 94-10072
The early stages of microbial colonization and succession of wooden surfaces exposed to the sea have been extensively studied as have the community structures of archaeological timbers subjected to submergence and then retrieval from the sea. The frigate UNICORN, a largely intact 19th century wooden ship based in Dundee, Scotland, provides the microbial ecologist with a unique opportunity to study...

Wood protecting chemicals for the 21st century
1993 - IRG/WP 93-30018
After assessing the past research with protection chemicals, this paper proposes future avenues for research and development in wood protection. Three scenarios are put forward for consideration. First, more is not better and future systems will emphasize combination formulations which enhance properties while providing biological efficacy. Second, current systems, especially those based on copper...

Degradations and conservation strategies for an XVIII-th century wooden church from Oltenia County, Romania
2010 - IRG/WP 10-40521

The church from Ursi village, Oltenia County, represents a particular case, the church being abandoned since 1913. The lack of a roof for a long time resulted in severe deterioration of the whole structure. Yet the inner and outer wall...

In-situ experimental treatment and consolidation of degraded timber elements from a XIX century building
2012 - IRG/WP 12-10767
This paper presents the in situ experimental conservation work performed on three timber structural elements from a XIX century building: two floor beams and one roof beam. The palace was built in 1877 in the centre of Lisbon initially with residential purposes. It has four floors, with timber structural horizontal elements, stairs and roof beams (generally of Pinus sylvestris L.). The exterior wa...
