I bought a vintage glass negative that arrived broken due to poor (ie non-existent) packaging. It's a 6x9 plate that is now in approx 10 pieces - 5 large & 5 small. I should probably bin it, however I really like the image, which is why I originally purchased it. So I'm trying to think of the best way to stick it back together again. I'm assuming this will be done with glue applied to the edges where they fit together. But what glue is best & are there any technique tips? It occurs to me that this must have been a somewhat common occurence in the days when a lot of people shot on glass, so I'm hoping some of that knowledge might be available here.
