Chemistry behind Silvering chemicals

My name is Fernando and I work at a company which produces rear view mirrors. I'd like to know where I can find information about silvering chemicals ( for example: What is the function of each chemical component at the silvering chemicals formula) Why I have to use ammonia ⇦this on eBay or Amazon [affil links] for example. I will appreciate a help from you because here is very difficult to find some information.

Hi Fernando,

After chemical mix well at alkaline PH the reduction of metallic silver take place on glass and gave mirror. Here is the simple discuss of making mirror.

I would like to make my own mirrors. Does anyone know and want to help me how to prepare silvering solutions? I know standard processes, but it does not satisfy me. If I used Valspar products, silver was O.K., but these solutions are too expensive. Thank you.
