How to make glass adhere to silver ?

I make jewelry and I've managed to fill a copper loop with tainted glass. I hold the copper and glass in the hottest part of the flame of my little butane/propane torch. But when I try to do the same thing with silver wire, the silver melts before the glass does. I guess that is because silver isn't such a good conducter of heat. So I've tried to heat up the entire peace of silver (instead of just the little loop that I'm trying to melt the glass on) , which works a little better. But even if I do get the silver and the glass red hot at the same time without the silver melting together, I can't make the glass adhere to the silver like it did to the copper. Any tips?

Hi, I know this response is incredibly late, however I feel it a duty of mine to share a new enameling technique with you.

Painting with Fire's Torch-Fired Enameling Technique. check them out at www.paintingwithfirestudio.com

With this technique you have the convenience to set up your station almost anywhere that you have some air circulation. Instead of spending a thousand dollars to get started with enameling, you can purchase a torch firing kit for around $120, the only thing you'd need to retrieve yourself is a tank of mapgas or propane.

This technique is great for adhering sterling silver

It take approximately between 30 seconds to a minute to complete a finished product. (Painting with Fire teaches their technique through the form of beads and jewelry)

Torch-Fired enameling is essentially powdered glass on metal such as Iron, copper, silver, or gold.

They teach workshops online and on site at their location in Saint Petersburg,FL

You need to get both to a consistent temp. This is not easy to do with a torch. I would suggest an enameling kiln. They are pricey but will get the job done. If you do not have one you might see if you know anyone who does or has a ceramic kiln. You need to get the temp to the point of melting glass but not the silver, it needs to shut off when the desired temp is reached then allowed to stay in the kiln until it cools completely. They have small enameling kilns at places like www.enasco.com that might work for what you are doing so you do not have to invest in a $1000 kiln.

You could use copper and then plate it
?

As long as you plate after fusing, that's a great idea. Plating before fusing just makes a big eutectic mess. Don't ask me how I know that.
Try using powdered or chunked enamel instead of regular glass. Properly formulated enamels stick beautifully to both silver and copper most of the time.
the silver is the best conductor for electricity and heat...try this,i've seen when i went to ferrari factory...made the loop a little tiny than the glass,then freeze the glass at the lower temperature you can without break it,insert in the silver at normal temperature and wait the glass restore the normal temperature,the thermic expansion will lock the glass in the loop...

Glass melts at ~1720F. Silver melts at ~1765F. The torch is capable of melting either. I'd suggest that the glass should be premelted, and only after apply the glass to the silver. (or visa versa)

Or get clever and use acrylic instead of glass.

Alternatively, use an oven that has good temperature control and use a cloisonnes like approach (I have no idea how it's actually spelled, shame on me). Basically, fill the loop with a clear glazing compound like those used in pottery or cloisonnes, then force melt below the melt temp of the silver.
