Problems in electroless Ag on glass

I am student in HK and doing research on electroless Ag on glass. I used AgNO3 and Glucose system to electroless Ag. However, it is hard to control the reaction of electroless process. In most of time, the solution turned to black and no coating was obtained. What is wronge in my experiment? Is there some trick related to the process? I first get the Ag(NH4) solution, and mixed with the reduced solution-Glucose when coating. Thanks for your attention and response in advance!

Wicker,
Where did you get the info. on how to make an electroless or immersion silver? Are you using etch and catalyst processes? If so, what are they? You have to be more descriptive about how you are conducting your experiments for anyone on this forum to help you.
