As a stained glass restorer, I would not melt the solder to
disassemble a zinc window. There is a possibility that you will
damage the zinc channel. I would first scrape the solder joint with
a knife or metal burnisher till I got to shinny metal. Then I would
use a fine kerf saw blade and a Dremel tool and cut the joints. Do
the glass repairs and when resolder the zinc. To resolder use zinc
chloride flux, 100-150 watt soldering iron  and a small amount of
60/40 solder. I some cases you don't need to add new solder at all,
simply remelt the old solder.
