How to do silvering using reducing agents
I wish to silver some seeds that I'd like to metallize with copper and after that, with a noble metal (silver / gold). I washed the seeds with common soap , after this, I washed with distilled water. I put them in a solution with stannous chloride (Sn Cl2) + HCl to order to sensitize then. I washed them with distilled water to remove the solution.
I prepared a solution with silver nitrate (Ag NO3) and put ammonium NH4OH till I observed a precipitated (White). Then I put the seeds into solution and took a solution (diluted glucose) to reduce the silver like a mirror over all the seeds. This did not occur. What happened? What other reducing agent could I used to? Rochelle salt? Formol? How can I use these agents ? What the difference among these reducing agents? Can you help me?
Thanks for yours help.Alq Sergio Costa

Ed. note: Khair is apparently alluding to explosive silver fulminates which can be created in this process. Carefully research that topic before any such experiments.
