For the Cité de la Musique, the philharmonic hall in Paris, we were just allowed to treat musical instruments with the mobile, ecological Thermo Lignum system.
The International Council of Museums uses images of objects treated with the Thermo Lignum Warmair process as part of the joint call by ICOM & ICOMOS for the use of nitrogen in art and culture - a thoroughly ironic faux pas. We have reacted to this with a letter.
