Help needed with heirloom repair.

Not sure if this is the right place but I'm relying on the wealth of knowledge here GS-netters!

I inherited a glass bowl from my mum when she passed. I seem to recall it may have been a wedding present when my parent's married in 1946 but I can't verify this.

It isn't worth anything as it had three glass legs but two are chipped so I use it a a fruit bowl.

I wash it occasionally and the other day the silver trim came off in the water. I don't think this is solid silver because it has never tarnished.

The cement/glue inside was flaking away and I realised it needed removing before re-sticking.

I'm just wondering what sortof glue I should use to put it back, and also how to best get rid of the remaining glue- which I suspect may have been there for eighty years!

Hoping someone can give me some good advice!
