24th October 2017 | Sint-Baafs Cathedral | Ghent (Belgium)

After Oslo and Vienna, Ghent was the third city to host the Nano-Cathedral local workshop.
On Tuesday the 24th of October, local professionals in field of architecture and stone conservation were provided with a program consisting of theoretical lectures in the morning and practical demonstrations in the afternoon. The lectures were deal with the issues surrounding the Balegem stone, existing and innovative techniques for its conservation, and the research conducted in the Nano-Cathedral project.
In the afternoon, several test methods was demonstrated, giving participants insight in state of the art research procedures and the assessment and comparison of new and existing products. On top of that, partakers got the chance to get acquainted with products available on the market and get the opportunity to visit the test sites on the Cathedral.
To end the day, external local researchers presented their own findings and test results to the audience to provide an overview of local and international research around a century-old problem: the conservation of Balegem Stone.
