# Extracting silver from Tollens test

When we add tollens reagent (diamminesilver(I) cation, $\ce{[Ag(NH3)2]+}$) to glucose it forms a silvery mirror on the walls of the container. Since the sides are coated with actual Silver,

1. is there any possible reagent/method to take the silver out from the sides of the test tube.?

2. will it be in its pure form or will there be organic/inorganic impurities?
