Humidity chambers and their application to the treatment of deformations in fabric‐supported paintings

Using the humidity chamber it was possible to introduce moisture into an Indian cloth painting in a controlled manner. High RH was produced by saturated salt solutions. In conjunction with further structural treatment outside the chamber, deformations were corrected in a painting which was particularly sensitive to moisture and where physically wetting the object would certainly have resulted in damage.
