Reactions to the study showing how corrosion has turned the Alhambra's gold leaf into purple nanospheres

Although gold is chemically inert, i.e. it resists discolouration and corrosion, its alloys are less resistant. This type of metal in the form of gold leaf is present in the Alhambra in Granada. Two researchers from the University of Granada analyse in the journal Science Advances what causes this corrosion and why purple-coloured nanospheres have appeared.
