Fine tuning of desalination poultices: try-outs in practice

B. Lubelli, R. P. J. Van Hees & H. De Clercq
Desalination by poulticing of sculptures and building elements is a technique increasingly usedin the field of (architectural) heritage conservation. However, desalination is still largelyperformed on a trial and error basis, without scientific knowledge of the transport mechanismsgoverning the process of salt extraction. In the framework of the EU project DESALINATION, amodular system of poultices has been developed, which is related to the pore size distribution ofdifferent types of substrates. Desalination according to this approach was...
