Some are exterior installations, set up in public space; others are in the collections of museums, corporations or individuals, while others are part of the imposing corpus of our religious heritage. Whether we are dealing with damaged objects, or those weathered by the years… that irreparable outrage, their repair requires the services of qualified professionals who—besides manual dexterity—possess skills in physics and chemistry as well as knowledge of art history.
