How to do silvering of glass with a gradient

I make packaging prototypes. I have a customer who showed me a sample glass bottle with a "chrome" gradient on one side. It goes from about 100% "silver" on top and fades out to 0% about half way down. Does any one know how this is done? And maybe where I could get it done?

Hi, Thomas. I think this is just two-part silvering. Silver nitrate [on eBay or Amazon] and a reducing solution are simultaneously sprayed out from a two-part spray gun. When they meet, the silver is reduced to metallic form. It's probably just sprayed many passes at the top, gradually reducing down to one fast coat where it fades out (not much different than what you could do with spray paint, but with silver).
