Put newspaper between the panes. Broadsheet if you can find them. Fold them over the edges, lay next sheets on top, next pane, repeat. You can then move about six panes at a time and they won't be stuck together when you want to reassemble.

This is also a good idea if you are washing them before the remantling as wet panes are a pain to seperate when wet.
