It's going to be very hard to get an answer simply because of the type of glass you used. The silver glasses have dozens of reactions, and because of that, you may not be able to tell one from the other. Unless you have only one kind of silver glass.
If this was the Italian glass, CiM, Bullseye, or any of the 96 COEs, then we might be able to figure it out. Because most of those are WYSIWYG. (what you see is what you get)
