Can someone please tell me the paragraph-length overview of the process of a panel repair. A panel that I made broke and later fell. A number of pieces are damaged and I'd like to totally re-lead it. My inkling of the process is something like this:
Number the pieces or trace them so you know where they go.
    Soak the panel in some stuff (what stuff, water?)
    Hack at the leads with cutting pliers and get them off
    scrape the putty off
    Replace or repair the damage
    Relead the pieces

The center panel (see attached) is cracked diagonally. I'd like to glue it. The crack started before the piece fell. I suspect it was an annealing issue with the fusing on the glass. My kiln may have had an element out, or I may have been negligent in allowing sufficient annealing. My plan is to reanneal it, then glue it. It will be my first experience with hxtal, or whatever HIS Glassworks recommends. I watched Mary Higgins work with it once at a conference. Seems straightforward. The broken border pieces, I will have to re-make. I really love the way they look, but they were weak and I need to find a more robust way to do what they did. But then again, if the gluing is fun, maybe I'll just glue them

Don, make a rubbing first, and number all the pieces, unless you still have original pattern.....

1- are all the numbered pieces broken?
2- why do you want to relead it?
3-If the center cracked because of stress. The stress is
now released. So I don't see a need to refire. If the
glass is in plane and the crack is tight and clean, you
can glue it in the leads
4-If the putty is not hard, no need to soak. You should be
able to cut and pull everything apart

I called Vic and we discussed the problem. Vic talked me out of disassembling and releading the panel. I got some epoxy from HIS glassworks. I put the panel on a 60° angle easel and I used this stretchy silicone tape called ZIP System Stretch Tape. It's tenacious and stretchy and holds the pieces together pretty well. There's still an offset ridge between the two pieces of glass perceptible under fingertip, but it's pretty small. I can't get the ridge to completely go away with hand pressure, so I'm going to live with it. What's troubling me now is that I can only tape one side, the smooth side. The other side is so rough and gravelly with fused junk that I'd never get tape to stick, or the glue to absorb into the crack from that side. Can I glue on the taped side, in a few places, so that it stays where I want it to, leave it dry for a week or two, then remove the tape and finish the rest of the glueing from that same smooth side?

cover the crack on the smooth side with tape and burnish well. Lay the panel flat on a light table, you want to warm the glass a little. Apply a small amount of glue at a time on the rough side. When the glue gets tacky, clean with a Q-tip that is just DAMP with acetone. Let sit for about a week.

Thanks Vic. I applied the glue last night. We'll see.
