I was very interested to read your message about the use of saliva in conservation. I am currently researching for my own thesis and am considering looking into potentially harmful saliva residues and the effect of rinsing. My particular interest is gilded surfaces (though I am also thinking about stone). From my experience, rinsing is not always general practice when cleaning with saliva, though it does seem to be with enzymes and chelating agents. Also, it may prove problematic on vulnerable gilded surfaces (if using water or alcohol, for example). The other area I am interested in researching is whether saliva's cleaning efficacy can be increased, by alteration of diet for example, or by buffering solutions to modify pH. But I am unsure whether this would be possible, given time restraints. **** Moderator's comments: Ms Yallop is not currently a DistList participant but has published on the subject.
