Hi Tom, It would be a real boon to have some sort of standard quantitative analysis of silver content which could be done in a home lab/kitchen. a titration method maybe? which would involve simple reagents and glassware. I think another way would be a colorimetric method or turbidity meter kind of thing which would involve test slides or a photometer of some sort.
Do you , or anyone have any thoughts on this?
