In Silver Mirroring
Tollens' reagent is also used to apply a silver mirror to glassware; for example the inside of an insulated vacuum flask. Around 500 mL of solution is prepared, much more than would be made for analytical use. This is then introduced to the clean glass surface which is to be mirrored and the solution reduced using a glucose solution. For a high quality finish the glass surface is cleaned using an oxidizing acid to remove all traces of organic compounds and the glass surface is pretreated with aqueous tin(II) chloride.
