Gluing euro coins together?? Answered

I have some coins from various countries that I have visited and would love to make use of them. I would like to create a bowl using all of the coins but have not found a glue strong enough to keep them together. Could anyone please assist? I have attached an image of what I would like to create


You might consider soldering or brazing the coins together (which is what I think they did with that bowl).

If you can't do that, maybe shape the coins around a balloon: use a dot of superglue to glue the coins edge-to-edge over the balloon. It won't be a hugely strong bond, but it should last long enough for you to "paint" over the coins with a clear casting resin (like the various "penny table" instructables).

You have very little area for the glue, so the only thing I woud consider working is a strong 2K glue.

Although for a bowl you could also consider using clear casting resin to create water tight bowl with the coins embedded in the resin.
