Resetting glass in old cabinet doors?
I have a few glass front cabinet doors that either need a pane replaced or else need the existing pane reset because it's loose. I am not sure how to do this, because there is no molding on the inside of the door to keep the glass in place. The only thing keeping the glass in the door is some kind of glazing (?) that is very brittle and crumbling off. The doors are all about 100 years old.
What would be the best way to replace/reset the glass panes back into the doors? I want to make sure the glass stays in place even if the door is accidentally banged shut. Adhesive doesn't seem like it would be enough.
