Yes indium will wet glass and is a main or entire constituent of solders
for glass. You also get some other weird thing such as mercury
replacement alloys with indium. One URL is www.indium.com . Would like
to try it as I blow glass and soldering it sounded interesting. Tried to
get some and got a quote of £10/gram and minimum 25 grams. Didn't want
to spend that much. I think its about the same price as 24 carat gold.

I also have soldered glass. Yes, solder wets glass. It's a process used in
making some scientific apparatus, which is where I learned how to do it.
Don't ask me the details; it's been too long for me to remember.


I wonder if the alloy contained gallium or indium?
