COST ACTION IE0601  FOCUSSED MEETING

‘ALLOWABLE MICROCLIMATIC VARIATIONS FOR POLYCHROME WOOD’

February 18-19, 2010, Oslo, Norway

This Focussed Meeting was organized in conjunction with the final workshop of the research project ‘Establishing standards for allowable microclimatic variations for polychrome wood’ implemented by the Institute of Catalysis and Surface Chemistry, Polish Academy of Sciences in Krakow and the Norwegian Institute for Cultural Heritage Research in Oslo, supported by a grant from Iceland, Lichtenstein and Norway through the European Economy Area (EEA) Financial Mechanism.

The meeting brought together 18 COST experts from 9 countries to discuss the particular issues of the preservation of painted wood. The meeting had additional 2 experts from USA and 48 attendees from 6 countries inscribed in the COST action.
