Hey,
Does anyone have experience attaching silver things to red tree coral.
I have some nice coral I bought at a show and I'd like to attach a casting
to it.

I imagine glue won't stick and heat will destroy it, so mechanical
attachmnets are the norm.

Are you wanting to cap it?
Can you be a little more vague?
