From previous reading I understand that a dilute 10% solution of Kodak Rapid Selenium Toner was recommended at one point to test for residual silver on fibre base photographic paper via placing drops onto the print surface (checking for colour change) as an alternative to a sulphide solution. Any thoughts on current knowledge with regard to the effectiveness of this test?
