The mural paintings from
northern Moldavia have always been a point of interest for specialists
in conservation, due to their technical qualities that assured their
preservation over the years in the severe climate of this region in
Romania.
Over the years, both exterior and interior paintings
showed colour alterations caused by environmental factors like
atmospheric deposits, humidity and light among others. Through
physical, chemical or biological processes, these factors induced
superficial chromatic alterations of the colours, modifying the
artistic expression of the paintings.
These alterations are generally considered as patina.
