Abstract
During the 17th and 18th centuries altarpiece painting techniques incorporated the use coloured resin based coating materials to confer a glow effect of enhanced brightness. These coatings (of <50 micrometers in thickness) were generally applied over metal foils of silver or gold. Over time these materials aged, their composition appears altered as a consequence of chemical interactions with other materials presents in the painting as well as in the atmosphere, with such effect enhanced by envir...
