I have an antique wooden box which has a nasty crack in it. There is a very dark brown material that seems to form the background of the image and which I would need to fill the crack (I think). Here is a picture of the whole box (perhaps this helps date the period or technique used) and a zoomed in view of one of the cracks:
Does anyone know what kind of material this might be - and what I could use as a good substitute (assuming that the "old" material might be hard to get hold of)? This box has no commercial value (AFAIK) but lots of sentimental value - so I would like to do this right if possible (I experimented a bit with epoxy and tinting powder and so far the results are not even close).
